The Cretaceous ( IPA : / k r ɪ ˈ t eɪ ʃ ə s / krih- TAY -shəss ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era , as well as the longest. At around 79   million years, it is the ninth and longest geological period of the entire Phanerozoic . The name is derived from the Latin creta , ' chalk ', which is abundant in the latter half of the period. It is usually abbreviated K , for its German translation Kreide .

173-619: Holderness is an area of the East Riding of Yorkshire , on the north-east coast of England. An area of rich agricultural land, Holderness was marshland until it was drained in the Middle Ages . Topographically , Holderness has more in common with the Netherlands than with other parts of Yorkshire. To the north and west are the Yorkshire Wolds . Holderness generally refers to the area between

346-538: A Berriasian–Barremian warm-dry phase, an Aptian–Santonian warm-wet phase, and a Campanian–Maastrichtian cool-dry phase. As in the Cenozoic, the 400,000 year eccentricity cycle was the dominant orbital cycle governing carbon flux between different reservoirs and influencing global climate. The location of the Intertropical Convergence Zone (ITCZ) was roughly the same as in the present. The cooling trend of

519-652: A charity, provides a community transport service for North Holderness, taking people to medical appointments in Hull and to the shops. The Humber Bridge , a road-only bridge, part of the A15 , links Hessle , west of Hull, with Barton-upon-Humber in Lincolnshire. West of this, the next crossing of the river (the Ouse at this point) are three bridges near Goole : a railway bridge, the M62 bridge and

692-541: A city of its size, with the census reporting 97.7% white. Areas of the East Riding show significant signs of affluence, including the Parliamentary constituency of Haltemprice and Howden which consists of middle-class areas such as: the suburb of Willerby , suburb of Kirk Ella , village of North Ferriby , and village of Swanland . Much of the area is affluent and has one of the highest proportions of owner-occupiers in

865-450: A density of 1.4 people per hectare. The most populous parishes in the main 2001 census were Bridlington (34,000), Goole (17,000), Beverley (17,000), Cottingham (17,000, by Hull), Hessle (15,000, by Hull), Driffield (11,000), Anlaby with Anlaby Common (10,000, by Hull), Hornsea (8,000) and Willerby (8,000), Pocklington (8,000) and Elloughton-cum-Brough (7,000). Half the district's population reside in these 11 parishes, with

1038-477: A diverse range of plants and animals. The upper tributaries of the river originate on the edge of the Yorkshire Wolds before entering the area of glacial and alluvial deposits of Holderness. The river bed varies in composition reflecting the underlying geology. In the upper reaches of the river water crowfoot , lesser water parsnip , mare's-tail and spiked water-milfoil may be found in the main channel whilst

1211-563: A fall in sea level. The lower-lying land was used for stock breeding . During the last years of Roman Britain, Anglo-Saxon raiders were troubling the area. After the Romans, the Brythonic -speaking area became known as Deira . By the second half of the 5th century, the continued settlement by the Angles caused a shift to Old English . Deira merged into Northumbria and village names containing

1384-682: A four-star rating, which places the authority as one of the best in the country. For representation in the Parliament of the United Kingdom the bulk of the East Riding district is divided into three county constituencies : Beverley and Holderness , Bridlington and the Wolds and Goole and Pocklington . The Kingston upon Hull area is divided into three constituencies; Kingston upon Hull North and Cottingham , Kingston upon Hull East , and Kingston upon Hull West and Haltemprice . Until 1 April 2009,

1557-597: A geologic signature associated with the mass extinction that lies between the Mesozoic and Cenozoic Eras . The Cretaceous as a separate period was first defined by Belgian geologist Jean d'Omalius d'Halloy in 1822 as the Terrain Crétacé , using strata in the Paris Basin and named for the extensive beds of chalk ( calcium carbonate deposited by the shells of marine invertebrates , principally coccoliths ), found in

1730-399: A lot of water was still locked in the northern ice sheets, sea level was much lower than in the present day and an area of land stretched eastwards to the low countries. The Wolds area takes the form of an elevated, gently rolling plateau , cut by numerous deep, steep-sided, flat-bottomed valleys of glacial origin. The chalk formation of the hills provides exceptionally good drainage, with

1903-533: A low level drainage system operates to collect the water. In the middle and lower reaches of the River Hull water is pumped from the low level drains into a high level system. This system consists of elevated water courses bounded by embankments. It drains by gravity into the sea. The main drain is the Holderness Drain , begun in 1764 by the engineer John Grundy Jr. In the east and south-east of Holderness there

2076-403: A person and burglary. Christianity is the religion with the largest following in the area, with 53.3% residents so identifying in the 2021 UK census . These census figures show no other single religion returned affiliation, as a percentage of population, above the national average for England. At the time of the 2021 census the population of the East Riding was 342,215 and its ethnic composition

2249-488: A promontory, or nose-shape, either in a river or jutting from a coastline. After the Norman Conquest of England the extensive Lordship of Holderness was given by King William I to Drogo de la Beuvrière , a Flemish supporter. This Drogo built a castle at Skipsea before 1087 when his estates were confiscated by the king. The area was then given to Adelaide of Normandy , and the title to her husband, Odo , but this

2422-403: A range of facilities and the bigger local centres of Bridlington and Beverley are regularly used by Holderness people. Hull is the largest commercial centre which is regularly used and it provides employment for a significant proportion of the population. Agriculture is the traditional employment of the area and there is a substantial area of horticultural development on the flat fertile land in

2595-532: A smaller territorial range and as population levels increased, they started to try to modify or control the natural world. In the Great Wold Valley , pollen samples of Mesolithic date indicate that the forest cover in the area was being disturbed and altered by man, and that open grasslands were being created. The Yorkshire Wolds became a major focus for human settlement during the Neolithic period as they had

2768-660: A straight shell, flourished in the seas along with reef-building rudist clams. Inoceramids were also particularly notable among Cretaceous bivalves, and they have been used to identify major biotic turnovers such as at the Turonian-Coniacian boundary. Predatory gastropods with drilling habits were widespread. Globotruncanid foraminifera and echinoderms such as sea urchins and starfish (sea stars) thrived. Ostracods were abundant in Cretaceous marine settings; ostracod species characterised by high male sexual investment had

2941-526: A wet and swampy area which became the plain of Holderness . Another ice sheet in the Vale of York retreated at the same time leaving thick glacial deposits and two prominent moraines to the west of the Wolds. These Vale of York deposits also formed wetlands . The Wolds themselves were largely ice-free, well-drained, chalk uplands. Gradually the tundra conditions that had existed as the ice retreated gave way to vegetation that could support grazing fauna. Because

3114-547: A wide range of natural resources. The oldest monuments found on the Wolds are the Neolithic long barrows and round barrows . Two earthen long barrows in the region are found at Fordon , on Willerby Wold, and at Kilham , near Driffield , both of which have radiocarbon dates of around 3700 BC. From around 2000 to 800 BC, the people of the Bronze Age built the 1,400 Bronze Age round barrows that are known to exist on

3287-536: A year on average or 2 million tonnes of material a year. Some of this is transported by longshore drift with about three percent of material being deposited at Spurn Point spit, to the south. The growth of Spurn Point is demonstrated by a series of lighthouses that have been built on the point. It is thought that approximately 3 miles (5 km) of land has been lost since the Roman era , including at least 23 towns/villages, including Ravenspurn . The Holderness coastline

3460-568: A year. Some of this is transported by longshore drift with about 3% of material being deposited at Spurn Head spit, to the south. The coastline has retreated noticeably in the last 2,000 years, with many former settlements now flooded, particularly Ravenser Odd and Ravenspurn , which was a major port until its destruction in the 14th century. Erosion is an ongoing concern in the area. The East Riding of Yorkshire Council has been carrying out cliff erosion defences between Sewerby and Kilnsea since 1951. The Holderness area drains mostly into

3633-551: A ~0.6 °C increase in temperature. The latter warming interval, occurring at the very end of the Cretaceous, was triggered by the activity of the Deccan Traps. The LKEPCI lasted into the Late Palaeocene , when it gave way to another supergreenhouse interval. The production of large quantities of magma, variously attributed to mantle plumes or to extensional tectonics , further pushed sea levels up, so that large areas of

3806-478: Is a beach with dunes which moves in response to the action of the waves. The wave action removes sand from the east of the beach and deposits it on the western side. The coast is influenced mainly by wave action but in the estuary the processes are driven by the power of the tides. The incoming tidal currents carry more sediment into the estuary than the ebb tides carry out. The estuary is shallow because of this constant deposition. Isostatic recoil is, however, causing

3979-570: Is a complex network of drains and streams that flow south into the Humber or east into the North Sea. To mitigate the effects of high tides stopping the water flow from these outlets, several have had pumping stations constructed at their outfalls. For the purpose of describing the natural history the area can be divided into three parts:- The River Hull valley dominates the western landscape of Holderness. The river and its associated wetland habitats support

4152-425: Is a particularly strong deficit in the number of young adults. There is a higher-than-average level of car ownership. 36.4% of all households do not have a car. Less than 5% of the population travel to work by public transport compared with 15% nationally. The district is one of the lowest non-white populations , with the census reporting 98.8% of the inhabitants being white. Hull itself is also quite monoethnic for

4325-546: Is a tour of East Yorkshire churches which were built, rebuilt or restored by the Sykes family of Sledmere House in the 19th century. The East Riding has only a small segment of motorway. Part of the M62 serves to link the Hull area to West Yorkshire and the national motorway network, while the M18 incidentally passes the district border near Goole. Primary roads in the district include

4498-491: Is access to the national motorway network via the A63 from Hull. Links to the continent are also via Hull, from where a daily ferry service to Rotterdam departs . A-class roads centre upon Hull and the coastal resort of Bridlington. Otherwise the A1033 road which connects Withernsea on the south-east coast to inland areas is the only main route in the area. The only remaining rail link

4671-459: Is by far the largest settlement, with population of 267,014, and is a major port and the county's economic and transport centre. The rest of the county is largely rural, and the next largest towns are the seaside resort of Bridlington (35,369) and the historic town of Beverley (30,351), which is also the county town . The county is governed by two unitary authorities, East Riding of Yorkshire Council and Hull City Council . It takes its name from

4844-475: Is dominated by deposits of till, boulder clays and glacial lake clays . These were deposited during the Devensian glaciation . The glacial deposits form a more or less continuous lowland plain which has some peat filled depressions (known locally as meres) which mark the presence of former lake beds. There are other glacial landscape features such as drumlin mounds, ridges and kettle holes scattered throughout

5017-466: Is drained by the River Hull and its tributaries and a number of coastal streams. The valley of the River Hull is broad and shallow and in its lower reaches the river is contained within flood banks. The River Hull Tidal Surge Barrier at the mouth of the river can be used to prevent surge tides overwhelming the flood defences. Large areas of Holderness are too flat and low to drain naturally so in these areas

5190-603: Is found in England, northern France, the low countries , northern Germany , Denmark and in the subsurface of the southern part of the North Sea . Chalk is not easily consolidated and the Chalk Group still consists of loose sediments in many places. The group also has other limestones and arenites . Among the fossils it contains are sea urchins , belemnites , ammonites and sea reptiles such as Mosasaurus . In southern Europe,

5363-563: Is particularly common and sand martin colonies have become established in places. Hornsea Mere is the largest natural lake in Yorkshire at 120 hectares. It has, besides the open fresh water habitat, marginal habitats of reed swamp, species-rich fen and carr woodland. It regularly supports populations of wintering wildfowl and the reed beds provide breeding sites for reed warblers. Characteristic plants include milk parsley , greater water parsnip and lesser reedmace . The intertidal system of

5536-658: Is susceptible to erosion due to the long north-easterly fetch, allowing for powerful waves, and the softness of the geology that make up the cliffs. Holderness is also a former bay that was filled in during the ice age and is now made up of chalk/glacial compounds that are easily eroded such as boulder clay . All the villages affected by the erosion are located on the north side of the Humber estuary . The area stretches from Flamborough Head (high chalk cliffs, just north of Bridlington) down to Spurn Point (sand spit, on above map). Villages such as Ravenser, which sent representatives to

5709-627: Is the Yorkshire Coast Line that runs between Hull in the south and Bridlington and it tends to skirt the area towards the west. Until the 1960s there were lines from Hull to both Hornsea and Withernsea , but these were closed by the Beeching cuts . Furthermore, in 1901 there was a proposal to construct the North Holderness Light Railway from Beverley to North Frodingham railway station , but this came to nothing. As part of

5882-630: Is the most populous of coastal settlements, others include Flamborough , Hornsea, Withernsea and Aldbrough . Settlements on the flat agricultural area of Holderness are Hedon and Roos and in the Great Wold Valley is Rudston . Beverley , Bishop Burton , Driffield, Cottingham and Lockington lie is the Yorkshire Wolds eastern foot. Low-lying lands close to the Humber Estuary are Goole , Brough , North Ferriby , Hessle and Kirk Ella . Stamford Bridge , Pocklington , Market Weighton , Holme-on-Spalding-Moor , Howden and South Cave all lie to

6055-625: Is the site of the famous battle, and the Yorkshire Wolds Way is a long-distance footpath that takes a winding route through the Yorkshire Wolds to Filey . Most of the East Riding is in the East Riding Archdeaconry of the Church of England Diocese of York . The archdeaconry includes the Yorkshire Wolds and the City of Hull, with a coastline extending from Scarborough and Bridlington in

6228-481: The A614 . Cretaceous The Cretaceous was a period with a relatively warm climate , resulting in high eustatic sea levels that created numerous shallow inland seas . These oceans and seas were populated with now- extinct marine reptiles , ammonites , and rudists , while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during

6401-592: The A63 , A164 , A165 , A1034 , A166 , A1033 and the A1079 . Hull Paragon Interchange is a large railway station, served by the Selby Line to the west and the Yorkshire Coast Line to the north. See Railway stations in the East Riding of Yorkshire . Train operators active in the area are Hull Trains , London North Eastern Railway , Northern and TransPennine Express . Bus services are provided by several operators including First York , which provides services from

6574-522: The Conservative Party gained a majority of seats, including those of the Liberal Democrat and Labour Party leaders. The council has a leader-and-executive system , led by Steven Parnaby of the Conservative Party since its creation until his retirement at the 2019 election , when Richard Burton was elected as his replacement. On 13 May 2021, Jonathan Owen was elected as the new leader of

6747-439: The East Riding or East Yorkshire , is a ceremonial county in the Yorkshire and the Humber region of England. It borders North Yorkshire to the north and west, South Yorkshire to the south-west, and Lincolnshire to the south across the Humber Estuary . The city of Kingston upon Hull is the largest settlement. The county has an area of 2,479 km (957 sq mi) and a population of 600,259. Kingston upon Hull

6920-525: The East Riding , a historic subdivision of Yorkshire . In the east of the county the low-lying plain of Holderness is enclosed by a crescent of low chalk hills, the Yorkshire Wolds . The Wolds meet the sea at Flamborough Head, a chalk headland, while the Holderness coast to the south is characterised by clay cliffs. The west of the county is part of the Vale of York , the wide plain of the River Ure / Ouse ;

7093-670: The Local Government Act 1888 , administrative counties were formed on the existing historic county boundaries in England, but in Yorkshire, given the vast size of the county area, three administrative county councils were created, based on the historic boundaries of the three Ridings. A county council for the East Riding of Yorkshire (the East Riding County Council ) was set up in 1889, covering an administrative county local government area centred on Beverley and which had

South of Flamborough Head is Bridlington, which features several beaches, and at the far south-east of the district is the Spurn peninsula. Before the last ice age the eastern coastline of the area was located along the eastern foot of the Yorkshire Wolds where remnants of beaches have been discovered. The North Sea ice sheet deposited huge amounts of boulder clay as it retreated and this subsequently formed

7958-563: The River Hull and the North Sea . The Prime Meridian passes through Holderness just to the east of Patrington and through Tunstall to the north. Between 1974 and 1996, Holderness lay within the Borough of Holderness in Humberside . It gave its name to a wapentake until the 19th century, when its functions were replaced by other local government bodies, particularly after the Local Government Act 1888 . The city of Kingston upon Hull lies in

8131-464: The River Hull , which was also improved to aid navigation. The Market Weighton Canal connected the town directly to the Humber Estuary . The canals and canalisation of the county's rivers helped aid drainage to low-lying and ill-drained areas. The 19th century saw a rail network created. An early rail link was constructed between Filey and Bridlington in 1847 and the Malton to Driffield railway

8304-543: The Selli Event . Early Aptian tropical sea surface temperatures (SSTs) were 27–32 °C, based on TEX 86 measurements from the equatorial Pacific. During the Aptian, Milankovitch cycles governed the occurrence of anoxic events by modulating the intensity of the hydrological cycle and terrestrial runoff. The early Aptian was also notable for its millennial scale hyperarid events in the mid-latitudes of Asia. The BAWI itself

8477-707: The Turonian Age, based on isotopic evidence. However, this has subsequently been suggested to be the result of inconsistent isotopic proxies, with evidence of polar rainforests during this time interval at 82° S. Rafting by ice of stones into marine environments occurred during much of the Cretaceous, but evidence of deposition directly from glaciers is limited to the Early Cretaceous of the Eromanga Basin in southern Australia . Flowering plants (angiosperms) make up around 90% of living plant species today. Prior to

8996-463: The 16th century. Other large estates created from former monastic holdings were sold by the crown to private landowners in the 17th and 18th centuries. Piecemeal attempts were made to improve the poor drainage of the area and with the formation of drainage boards in the later 18th century flooding began to be controlled. The remaining wastes were added to farm land and the meres, fluctuating lakes, disappeared. The opening of railways from Hull accelerated

9169-964: The Albian regularly expanded northward in tandem with expansions of subtropical high pressure belts. The Cedar Mountain Formation's Soap Wash flora indicates a mean annual temperature of between 19 and 26 °C in Utah at the Albian-Cenomanian boundary. Tropical SSTs during the Cenomanian-Turonian Thermal Maximum were at least 30 °C, though one study estimated them as high as between 33 and 42 °C. An intermediate estimate of ~33-34 °C has also been given. Meanwhile, deep ocean temperatures were as much as 15 to 20 °C (27 to 36 °F) warmer than today's; one study estimated that deep ocean temperatures were between 12 and 20 °C during

9342-554: The Anglian elements -ing, -ingham or -ham started to be found in settlement names. As Christianity was established in the area from the 7th century onwards, several cemeteries like the one at Garton on the Wolds show evidence of the abandonment of pagan burial practices. In AD 867, the Great Danish Army captured the Anglian town of York. The remnants of the army settled from AD 876 as their leader Halfdan shared out

9515-480: The Cenomanian between the Albian and Turonian. The Cretaceous is divided into Early and Late Cretaceous epochs , or Lower and Upper Cretaceous series . In older literature, the Cretaceous is sometimes divided into three series: Neocomian (lower/early), Gallic (middle) and Senonian (upper/late). A subdivision into 12 stages , all originating from European stratigraphy, is now used worldwide. In many parts of

During the Cretaceous, the late- Paleozoic -to-early-Mesozoic supercontinent of Pangaea completed its tectonic breakup into the present-day continents , although their positions were substantially different at the time. As the Atlantic Ocean widened, the convergent-margin mountain building ( orogenies ) that had begun during the Jurassic continued in

10034-401: The Cretaceous is sharply defined, being placed at an iridium -rich layer found worldwide that is believed to be associated with the Chicxulub impact crater , with its boundaries circumscribing parts of the Yucatán Peninsula and extending into the Gulf of Mexico . This layer has been dated at 66.043 Mya. At the end of the Cretaceous, the impact of a large body with the Earth may have been

10207-402: The Cretaceous is usually a marine system consisting of competent limestone beds or incompetent marls . Because the Alpine mountain chains did not yet exist in the Cretaceous, these deposits formed on the southern edge of the European continental shelf , at the margin of the Tethys Ocean . During the Cretaceous, the present North American continent was isolated from the other continents. In

10380-425: The Cretaceous seas. Stagnation of deep sea currents in middle Cretaceous times caused anoxic conditions in the sea water leaving the deposited organic matter undecomposed. Half of the world's petroleum reserves were laid down at this time in the anoxic conditions of what would become the Persian Gulf and the Gulf of Mexico. In many places around the world, dark anoxic shales were formed during this interval, such as

Following the 2009 structural changes to local government in England it fell to fifth place by area and sixth place by population. The East Riding of Yorkshire covers 240,768 hectares (930 sq mi) and has a population of 335,049 (2008 Office for National Statistics mid-year estimates),

11072-458: The Holderness are the shelter against the worst of the moist westerly winds provided firstly by the Pennines and then the Yorkshire Wolds and the proximity of the North Sea. Generally, rainfall is 600 to 700 mm per year which is low compared with the national average rainfall of 1125 mm. Geologically, Holderness is underlain by Cretaceous chalk but in most places it is so deeply buried beneath glacial deposits that it has no influence on

11245-423: The Holderness area now lies within a number of different divisions. The Beverley and Holderness parliamentary constituency statistics have been used to provide a representative picture of the area. In 2004 there were 95,077 people living in the area in 41,224 households. Of these people 4.7% were aged below 25 years, 52.6% were aged between 25 and 55 years and 42.8% were 55 years old or more. The population density

11418-441: The Humber and the eponymous River Hull drains the area north of Hull. The western part of the district in the Vale of York borders on and is drained by the River Derwent . The landscape is generally low-lying and flat although minor ridges and glacial moraines provide some variations in topography. Where there are dry sandy soils there are remnants of historic heathlands and ancient semi-natural woodlands. Arable fields dominate

11591-423: The Humber estuary has local seagrass beds that provide feeding and wintering areas for over 133,000 waders and wildfowl. It is rich in invertebrate communities. The estuary also provides for breeding birds, grey seals and natterjack toads . Spurn Point at the tip of the Spurn peninsula is made of hard glacial moraine so is less liable to erosion than areas further north on the Holderness coast. The Spurn peninsula

Choristoderes , a group of freshwater aquatic reptiles that first appeared during the preceding Jurassic, underwent a major evolutionary radiation in Asia during the Early Cretaceous, which represents the high point of choristoderan diversity, including long necked forms such as Hyphalosaurus and

12283-399: The Late Cretaceous-Early Palaeogene Cool Interval (LKEPCI). Tropical SSTs declined from around 35 °C in the early Campanian to around 28 °C in the Maastrichtian. Deep ocean temperatures declined to 9 to 12 °C, though the shallow temperature gradient between tropical and polar seas remained. Regional conditions in the Western Interior Seaway changed little between the MKH and

12456-656: The MKH. Mean annual temperatures at the poles during the MKH exceeded 14 °C. Such hot temperatures during the MKH resulted in a very gentle temperature gradient from the equator to the poles; the latitudinal temperature gradient during the Cenomanian-Turonian Thermal Maximum was 0.54 °C per ° latitude for the Southern Hemisphere and 0.49 °C per ° latitude for the Northern Hemisphere, in contrast to present day values of 1.07 and 0.69 °C per ° latitude for

12629-516: The MKH. The poles were so warm that ectothermic reptiles were able to inhabit them. Beginning in the Santonian, near the end of the MKH, the global climate began to cool, with this cooling trend continuing across the Campanian. This period of cooling, driven by falling levels of atmospheric carbon dioxide, caused the end of the MKH and the transition into a cooler climatic interval, known formally as

12802-453: The Maastrichtian, bucking the trend of overall cooler temperatures during the LKEPCI. Between 70 and 69 Ma and 66–65 Ma, isotopic ratios indicate elevated atmospheric CO 2 pressures with levels of 1000–1400 ppmV and mean annual temperatures in west Texas between 21 and 23 °C (70 and 73 °F). Atmospheric CO 2 and temperature relations indicate a doubling of pCO 2 was accompanied by

12975-639: The Mesozoic) ended with the Cretaceous–Paleogene extinction event , a large mass extinction in which many groups, including non-avian dinosaurs, pterosaurs , and large marine reptiles , died out, widely thought to have been caused by the impact of a large asteroid that formed the Chicxulub crater in the Gulf of Mexico. The end of the Cretaceous is defined by the abrupt Cretaceous–Paleogene boundary (K–Pg boundary),

13148-651: The South Atlantic and Indian Oceans were newly formed. Such active rifting lifted great undersea mountain chains along the welts, raising eustatic sea levels worldwide. To the north of Africa the Tethys Sea continued to narrow. During most of the Late Cretaceous, North America would be divided in two by the Western Interior Seaway , a large interior sea, separating Laramidia to the west and Appalachia to

13321-565: The Southern and Northern hemispheres, respectively. This meant weaker global winds, which drive the ocean currents, and resulted in less upwelling and more stagnant oceans than today. This is evidenced by widespread black shale deposition and frequent anoxic events . Tropical SSTs during the late Albian most likely averaged around 30 °C. Despite this high SST, seawater was not hypersaline at this time, as this would have required significantly higher temperatures still. On land, arid zones in

13494-560: The Tethys to the Arctic Ocean and enabling biotic exchange between the two oceans. At the peak of the Cretaceous transgression , one-third of Earth's present land area was submerged. The Cretaceous is justly famous for its chalk ; indeed, more chalk formed in the Cretaceous than in any other period in the Phanerozoic . Mid-ocean ridge activity—or rather, the circulation of seawater through

13667-504: The United Kingdom, the Holderness area generally has cool summers and relatively mild winters. The latitude of the area means that it is influenced by predominantly westerly winds with depressions and their associated fronts, bringing with them unsettled and windy weather, particularly in winter. The wind sometimes causes depositions to happen. Between depressions there are often small mobile anticyclones that bring periods of fair weather. In winter anticyclones bring cold dry weather. In summer

13840-625: The Vale of York were also being used for animal rearing at this time. In the Iron Age there were further cultural changes in the area. There emerged a distinctive local tradition known as the Arras Culture , named after a site at Arras, near Market Weighton . There are similarities between the chariot burials of the Arras Culture and groups of La Tène burials in northern Europe, where the burial of carts

14013-406: The Yorkshire Wolds. These are found both in isolation and grouped together to form cemeteries. Many of these sites can still be seen as prominent features in the present-day landscape. By the later Bronze Age, an open, cleared, landscape predominated on the Wolds. It was used for grazing and also for arable cultivation. The wetlands on either side of the Wolds in the River Hull valley, Holderness and

14186-425: The ancestors of modern-day birds also diversified. They inhabited every continent, and were even found in cold polar latitudes. Pterosaurs were common in the early and middle Cretaceous, but as the Cretaceous proceeded they declined for poorly understood reasons (once thought to be due to competition with early birds , but now it is understood avian adaptive radiation is not consistent with pterosaur decline ). By

14359-473: The anticyclones tend to bring dry settled conditions which can lead to drought, particularly on the Wolds. For its latitude this area is mild in winter and cooler in summer due to the influence of the Gulf Stream in the northern Atlantic Ocean. Air temperature varies on a daily and seasonal basis. The temperature is usually lower at night, and January is the coldest time of the year. The two dominant influences on

14532-407: The anticyclones tend to bring dry settled conditions which can lead to drought. For its latitude this area is mild in winter and cooler in summer due to the influence of the Gulf Stream in the northern Atlantic Ocean. Air temperature varies on a daily and seasonal basis. The temperature is usually lower at night and January is the coldest time of the year. The two dominant influences on the climate of

14705-562: The area became drier it was progressively cleared of trees and the higher drier parts were initially favoured for settlement. The Domesday survey reveals that in the reign of Edward the Confessor there were 45 different freeholders having land in Holderness. The name of Holderness may be derived from the Danish "hold" which was the name given in that language to a nobleman with considerable territorial possessions. The "ness" part generally refers to

14878-504: The area in which the Lord Lieutenant of the East Riding of Yorkshire represents the Crown , was re-established the same day, covering the City of Kingston upon Hull as well as the East Riding of Yorkshire Council area as did predecessor authorities. The East Riding of Yorkshire is entirely parished ; the City of Hull has no parishes. From 1996 Beverley had Charter Trustees to maintain

15051-559: The area included the abbeys of Meaux and Thornton and the priories of Swine, Nunkeeling and Bridlington. This land was confiscated and became crown property when Henry VIII ordered the Dissolution of the Monasteries in the 16th century. The Aumale lordship had also passed to the crown and was obtained along with some former monastic lands by the Constable family of Burton Constable in

15224-438: The area to sink at the rate of 3 mm annually and global warming is making the sea level rise. The combined effects of these processes mean that the sea in the estuary may be half a metre higher by the year 2050. A large area around the estuary consists of land which lies below the present high-water mark. Flood defences offer only a short-term and local answer and may actually increase the long-term risks. Managed realignment of

15397-498: The area. The well-drained glacial deposits provide fertile soils that can support intensive arable cultivation. Fields are generally large and bounded by drainage ditches. There is very little woodland in the area and this leads to a landscape that is essentially rural but very flat and exposed. The coast is subject to rapid marine erosion. The Holderness coastline suffers the highest rate of coastal erosion in Europe: 5 feet (1.5 m)

15570-449: The area. The well-drained glacial deposits provide fertile soils that can support intensive arable cultivation. Fields are generally large and bounded by drainage ditches . There is very little woodland in the area, and this leads to a landscape that is essentially rural but very flat and exposed. The Holderness coastline suffers the highest rate of coastal erosion in Europe: 2 metres a year on average or 2 million tonnes of material

15743-453: The charter of the borough of Beverley : these were replaced by a Beverley Town Council in 1999, and Bridlington was parished in 1999. The unparished area consisting of the urban district of Haltemprice was divided into various parishes in 1999 and 2000. The East Riding of Yorkshire Council is based at County Hall in Beverley , in the former headquarters of Humberside County Council , and

15916-534: The city of Hull . Beverley , a market town, is generally associated with affluence but, like any other town of its size, it also has areas that face disadvantage. Other areas of the East Riding of Yorkshire face significant deprivation. The seaside towns of Withernsea and Bridlington face similar challenges with unemployment, low educational attainment, and socioeconomic inequality. South East Holderness, consisting of small rural communities, deals with limited access to services, inadequate public transportation, and

16089-449: The climate of the area are the shelter against the worst of the moist westerly winds provided by the Pennines and the proximity of the North Sea. The East Riding of Yorkshire is divided into two council areas: Kingston upon Hull is managed by Hull City Council , and the rest of the county is managed by the East Riding of Yorkshire Council . A non-mayoral devolution deal was proposed for

16262-423: The coast by setting back the coastal defences will provide new intertidal habitats and harness natural equalising processes and is the preferred long-term solution. There is archaeological evidence to suggest that the first settlers in Holderness arrived in the Neolithic era when the plain was still very wet and most likely consisted of a mixture of marshes, lakes, islands and woodland. As the sea level changed and

16435-404: The coastline is vulnerable to erosion, on average losing six feet (1.8 m) a year. The coast and surrounding communities have had to implement managed retreat . The area has boundaries which are clearly defined by the rising land of the Yorkshire Wolds to the north and west, the North Sea to the east and the Humber Estuary to the south. There are no motorways in the area, however there

16608-408: The continental crust were covered with shallow seas. The Tethys Sea connecting the tropical oceans east to west also helped to warm the global climate. Warm-adapted plant fossils are known from localities as far north as Alaska and Greenland , while dinosaur fossils have been found within 15 degrees of the Cretaceous south pole . It was suggested that there was Antarctic marine glaciation in

16781-417: The cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the Cretaceous. During this time, new groups of mammals and birds appeared, including the earliest relatives of placentals & marsupials ( Eutheria and Metatheria respectively), and the earliest crown group birds. Acanthomorph fish,

16954-523: The council. Following the 2023 election the Conservative Party elected former deputy, Anne Handley, to be leader of the group. At the annual general meeting of the council on 18 May 2023 Handley was elected as leader of the council, with the Conservative Party running a minority administration with support of the independents. In the Audit Commission report covering 2007 the council was given

17127-410: The country. Other parts of the county are more diverse, including the suburbs of Hessle , Cottingham and Anlaby with Anlaby Common . These areas consist of a mix of housing tenures in a real range of properties, from small ex-authority estates, to grand period homes. Hessle and Cottingham in particular have seen a considerable amount of home building, supporting the regeneration and development of

17300-550: The county, a mayoral deal received approval from the Secretary of State as of September 2024. This would lead to the establishment of an East Yorkshire combined authority with powers over housing, job creation and public transport, including bus franchising. The administrative division of the East Riding of Yorkshire originated in antiquity. Unlike most counties in Great Britain, which were divided anciently into hundreds , Yorkshire

17473-433: The crown. The coastal trading town of Ravenser Odd , represented in the 13th century model parliament, was lost to the sea through storm and coastal erosion. Its seaport role was eventually taken over by the new town of Kingston upon Hull but until about 1400 by Hedon and Beverley as Hull was isolated by the surrounding marshes. Robin of Redesdale was responsible for raising the northern shires against King Edward IV in

17646-413: The decline of traditional industries. Goole , an inland port town, has experienced a decline in its socioeconomic characteristic. Akin to much of the West Riding, this has coincided with the decline of industry over the latter half of the 20th century. The crime rate in the East Riding is lower than the national average in robbery, sexual offences, theft of a vehicle, theft from a vehicle, violence against

17819-544: The early and mid-Cretaceous (becoming extinct during the late Cretaceous Cenomanian-Turonian anoxic event ), plesiosaurs throughout the entire period, and mosasaurs appearing in the Late Cretaceous. Sea turtles in the form of Cheloniidae and Panchelonioidea lived during the period and survived the extinction event. Panchelonioidea is today represented by a single species; the leatherback sea turtle . The Hesperornithiformes were flightless, marine diving birds that swam like grebes . Baculites , an ammonite genus with

17992-437: The east, then receded late in the period, leaving thick marine deposits sandwiched between coal beds. Bivalve palaeobiogeography also indicates that Africa was split in half by a shallow sea during the Coniacian and Santonian, connecting the Tethys with the South Atlantic by way of the central Sahara and Central Africa, which were then underwater. Yet another shallow seaway ran between what is now Norway and Greenland, connecting

18165-721: The end of the AACS, which ended around 111 Ma with the Paquier/Urbino Thermal Maximum, giving way to the Mid-Cretaceous Hothouse (MKH), which lasted from the early Albian until the early Campanian. Faster rates of seafloor spreading and entry of carbon dioxide into the atmosphere are believed to have initiated this period of extreme warmth, along with high flood basalt activity. The MKH was punctuated by multiple thermal maxima of extreme warmth. The Leenhardt Thermal Event (LTE) occurred around 110 Ma, followed shortly by

18338-497: The end of the Cretaceous. The high sea level and warm climate of the Cretaceous meant large areas of the continents were covered by warm, shallow seas, providing habitat for many marine organisms. The Cretaceous was named for the extensive chalk deposits of this age in Europe, but in many parts of the world, the deposits from the Cretaceous are of marine limestone , a rock type that is formed under warm, shallow marine conditions. Due to

18511-459: The end of the period only three highly specialized families remained; Pteranodontidae , Nyctosauridae , and Azhdarchidae . The Liaoning lagerstätte ( Yixian Formation ) in China is an important site, full of preserved remains of numerous types of small dinosaurs, birds and mammals, that provides a glimpse of life in the Early Cretaceous. The coelurosaur dinosaurs found there represent types of

18684-407: The enlarged ridges—enriched the oceans in calcium ; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton . These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas 's Smoky Hill Chalk Member and

18857-425: The erosion is not stopped then there will be millions of pounds of damage. However, one or more such groynes has had a detrimental effect further along the coast, in some areas resulting in erosion of up to 66 feet (20 m) per year initially, though over the long term erosion rates have been seen to revert to their original yearly average of closer to 6 feet 7 inches (2 m) a year. The Holderness area

19030-528: The extinction fed on insects , larvae , worms , and snails, which in turn fed on dead plant and animal matter. Scientists theorise that these organisms survived the collapse of plant-based food chains because they fed on detritus . In stream communities , few groups of animals became extinct. Stream communities rely less on food from living plants and more on detritus that washes in from land. This particular ecological niche buffered them from extinction. Similar, but more complex patterns have been found in

19203-554: The first records of the gharial-like Neochoristodera , which appear to have evolved in the regional absence of aquatic neosuchian crocodyliformes. During the Late Cretaceous the neochoristodere Champsosaurus was widely distributed across western North America. Due to the extreme climatic warmth in the Arctic, choristoderans were able to colonise it too during the Late Cretaceous. In the seas, rays , modern sharks and teleosts became common. Marine reptiles included ichthyosaurs in

19376-412: The former headquarters of East Riding County Council before that. There are 26 wards electing a total of 67 councillors in the district. The council elects on a four-yearly cycle with all seats up for election at the same time. It first had elections in 1995—a year before it came into its powers—as a shadow authority. Between 1995 and 2007 the council had No overall control . In the 2007 local elections

19549-495: The fort of Eboracum . There is evidence of extensive use of the light soils of the Wolds for grain farming in the Roman era. Several Roman villas which were the centres of large agricultural estates have been identified around Langton and Rudston . In the low-lying lands on either side of the Wolds there was an increase in the number of settlements between 500 BC and AD 500, as the land became drier and more accessible due to

19722-455: The gas refining process and is a major employer in the area. Tourism makes a significant contribution to the economy of Hornsea and Withernsea with Hornsea Pottery and Freeport attracting around a million visitors each year. " The Adventure of the Priory School ", a Sherlock Holmes mystery by Sir Arthur Conan Doyle , takes place mostly in Holderness. Also one of the main characters is

19895-493: The genus Berriasella , but its use as a stratigraphic indicator has been questioned, as its first appearance does not correlate with that of C. alpina . The boundary is officially considered by the International Commission on Stratigraphy to be approximately 145 million years ago, but other estimates have been proposed based on U-Pb geochronology, ranging as young as 140 million years ago. The upper boundary of

20068-620: The group Maniraptora , which includes modern birds and their closest non-avian relatives, such as dromaeosaurs , oviraptorosaurs , therizinosaurs , troodontids along with other avialans . Fossils of these dinosaurs from the Liaoning lagerstätte are notable for the presence of hair-like feathers . Insects diversified during the Cretaceous, and the oldest known ants , termites and some lepidopterans , akin to butterflies and moths , appeared. Aphids , grasshoppers and gall wasps appeared. Rhynchocephalians (which today only includes

20241-664: The growth of first Withernsea in 1854 and Hornsea in 1864 as coastal resorts and commuter towns of Hull. Many of the other settlements grew and changed their character from agricultural villages to become dormitory settlements of Hull, Beverley, Bridlington and Driffield. Sales of large landed estates have reduced many of the large agricultural holdings that were in private ownership but some still remain and some have been used to create large farming agri-businesses which manage considerable areas with few farms. The rail links to both Withernsea and Hornsea closed to passengers in 1964 and closed completely in 1965. Administratively and politically

20414-412: The high sea level, there was extensive space for such sedimentation . Because of the relatively young age and great thickness of the system, Cretaceous rocks are evident in many areas worldwide. Chalk is a rock type characteristic for (but not restricted to) the Cretaceous. It consists of coccoliths , microscopically small calcite skeletons of coccolithophores , a type of algae that prospered in

20587-546: The highest rates of extinction and turnover. Thylacocephala , a class of crustaceans, went extinct in the Late Cretaceous. The first radiation of the diatoms (generally siliceous shelled, rather than calcareous ) in the oceans occurred during the Cretaceous; freshwater diatoms did not appear until the Miocene . Calcareous nannoplankton were important components of the marine microbiota and important as biostratigraphic markers and recorders of environmental change. The Cretaceous

20760-574: The land already belonging to lay owners, they formed some of the vast estate holdings which continued to exist in the Riding until the 20th century. The 18th century saw a canal network form, the River Derwent was canalised as far upstream as Malton and was linked to Pocklington by the cutting of the Pocklington Canal . Other canals were cut to join the towns of Beverley and Driffield to

20933-690: The land cover of the area and grasslands are infrequent. There are very few flood meadows left, although some significant areas remain on the lower reaches of the River Derwent. The East Riding generally has cool summers and relatively mild winters. Weather conditions vary from day to day as well as from season to season. The latitude of the area means that it is influenced by predominantly westerly winds with depressions and their associated fronts, bringing with them unsettled and windy weather, particularly in winter. Between depressions there are often small mobile anticyclones that bring periods of fair weather. In winter, anticyclones bring cold dry weather. In summer

21106-639: The land. The Danish consolidated the area into the Kingdom of Jorvik , Danelaw then the Norse North Sea Empire . Scandinavian settlement names started to be found, such as -by and -thorpe. Scandinavian rule in the area came to an end in AD ;954 with the death of Eric Bloodaxe . After the Norman Conquest of England by William the Conqueror in AD 1066, land across England was granted to followers of

21279-445: The landscape. The landscape is dominated by deposits of till, boulder clays and glacial lake clays. These were deposited during the Devensian glaciation. The glacial deposits form a more or less continuous lowland plain which has some peat filled depressions (known locally as meres) which mark the presence of former lake beds. There are other glacial landscape features such as drumlin mounds, ridges and kettle holes scattered throughout

21452-743: The last epoch of the Jurassic, the Tithonian, continued into the Berriasian, the first age of the Cretaceous. The North Atlantic seaway opened and enabled the flow of cool water from the Boreal Ocean into the Tethys. There is evidence that snowfalls were common in the higher latitudes during this age, and the tropics became wetter than during the Triassic and Jurassic. Glaciation was restricted to high- latitude mountains, though seasonal snow may have existed farther from

21625-564: The late Valanginian (~ 134 million years ago) found in Israel and Italy, initially at low abundance. Molecular clock estimates conflict with fossil estimates, suggesting the diversification of crown-group angiosperms during the Late Triassic or the Jurassic, but such estimates are difficult to reconcile with the heavily sampled pollen record and the distinctive tricolpate to tricolporoidate (triple grooved) pollen of eudicot angiosperms. Among

21798-465: The late Cretaceous, and all else that depended on them suffered, as well. Herbivorous animals, which depended on plants and plankton as their food, died out as their food sources became scarce; consequently, the top predators , such as Tyrannosaurus rex , also perished. Yet only three major groups of tetrapods disappeared completely; the nonavian dinosaurs , the plesiosaurs and the pterosaurs . The other Cretaceous groups that did not survive into

21971-563: The latest Albian. Approximately 94 Ma, the Cenomanian-Turonian Thermal Maximum occurred, with this hyperthermal being the most extreme hothouse interval of the Cretaceous and being associated with a sea level highstand. Temperatures cooled down slightly over the next few million years, but then another thermal maximum, the Coniacian Thermal Maximum, happened, with this thermal event being dated to around 87 Ma. Atmospheric CO 2 levels may have varied by thousands of ppm throughout

22144-674: The l’Arboudeyesse Thermal Event (ATE) a million years later. Following these two hyperthermals was the Amadeus Thermal Maximum around 106 Ma, during the middle Albian. Then, around a million years after that, occurred the Petite Verol Thermal Event (PVTE). Afterwards, around 102.5 Ma, the Event 6 Thermal Event (EV6) took place; this event was itself followed by the Breistroffer Thermal Maximum around 101 Ma, during

22317-621: The marginal vegetation is composed of branched bur-reed , common reed and reed sweetgrass . Otters have recently recolonised the upper reaches of the river, yet the European water vole is now confined to a few isolated populations. Notable species of invertebrates include uncommon mayflies . There is a diverse breeding bird community including lapwing , snipe and common redshank . Wildfowl such as mallard and mute swans may also be seen, along with yellow wagtail , sedge warbler , reed warbler and reed bunting . Further south towards Hull

22490-508: The middle Cretaceous, becoming the dominant group of land plants by the end of the period, coincident with the decline of previously dominant groups such as conifers. The oldest known fossils of grasses are from the Albian , with the family having diversified into modern groups by the end of the Cretaceous. The oldest large angiosperm trees are known from the Turonian (c. 90 Mya) of New Jersey, with

22663-752: The monasteries, continued to improve and drain their holdings throughout the Middle Ages to maximise the rents they could charge for them. The governance structure in the Domesday survey of 1086 was Yorkshire , its ridings and Wapentakes —the latter two remnants of the Norse structure. In the mid-16th century Henry VIII of England dissolved the monasteries , resulting in the large areas of land owned by Meaux Abbey , Bridlington Priory and other monastic holdings being confiscated. The Crown subsequently sold these large tracts of land into private ownership. Along with

22836-456: The most diverse group of modern vertebrates, appeared in aquatic habitats around the middle of the Cretaceous. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by the end of the Cretaceous, coincident with the decline and extinction of previously widespread gymnosperm groups. The Cretaceous (along with

23009-470: The most promising candidates for fixing the Jurassic–Cretaceous boundary. In particular, the first appearance Calpionella alpina , coinciding with the base of the eponymous Alpina subzone, has been proposed as the definition of the base of the Cretaceous. The working definition for the boundary has often been placed as the first appearance of the ammonite Strambergella jacobi , formerly placed in

23182-596: The new Norman king and ecclesiastical institutions. When some of the northern earls rebelled, William retaliated with the Harrying of the North which laid waste to many northern villages. The land was then distributed among powerful barons, such as the Count of Aumale in Holderness and the Percy family in the Wolds and the Vale of York. These lay lords and ecclesiastical institutions, including

23355-422: The new county council name, two of the nine districts formed in the 1972 Act included East Yorkshire in their titles, though they only covered a fraction of the geographical East Yorkshire area ( East Yorkshire district , East Yorkshire Borough of Beverley ). Continued disquiet culminated in a number of local government reviews in the 1980s and 1990s. Twenty-two years after being set up, Humberside County Council

23528-599: The north and west of the area, between the River Derwent and the scarp slope of the Wolds. There are a wide range of interesting places to visit in the East Riding. These include historic buildings such as Burnby Hall , Burton Agnes Manor House , Burton Agnes Hall , Sewerby Hall , Skipsea Castle and the gun battery of Fort Paull . The religious edifices of the Rudston Monolith , Beverley Minster , Beverley Friary and Howden Minster can be visited at all seasons. The sails of Skidby Windmill can be seen providing

23701-435: The north to Spurn Point. The Middlesbrough Roman Catholic diocese covers Yorkshire's historic east and north ridings as well as the historic City of York. Notable religious sites include Beverley Minster , Howden Minster , Hull Minster and Bridlington Priory along with the historic parish church of St Augustine, Hedon , known as the 'King of Holderness', which is a Grade I listed building . The Sykes Churches Trail

23874-824: The oceans. Extinction was more severe among animals living in the water column than among animals living on or in the seafloor. Animals in the water column are almost entirely dependent on primary production from living phytoplankton, while animals living on or in the ocean floor feed on detritus or can switch to detritus feeding. The largest air-breathing survivors of the event, crocodilians and champsosaurs , were semiaquatic and had access to detritus. Modern crocodilians can live as scavengers and can survive for months without food and go into hibernation when conditions are unfavorable, and their young are small, grow slowly, and feed largely on invertebrates and dead organisms or fragments of organisms for their first few years. These characteristics have been linked to crocodilian survival at

24047-581: The oldest records of Angiosperm macrofossils are Montsechia from the Barremian aged Las Hoyas beds of Spain and Archaefructus from the Barremian-Aptian boundary Yixian Formation in China. Tricolpate pollen distinctive of eudicots first appears in the Late Barremian, while the earliest remains of monocots are known from the Aptian. Flowering plants underwent a rapid radiation beginning during

24220-499: The open farmland which supports golden plover and lapwing and a flora of arable weeds. The coast from Bridlington in the north to Spurn Point is an interesting complex of coastal processes. The soft cliffs of Holderness are subject to rapid erosion whilst the eroded material is being deposited on the Spurn peninsula. The speed of erosion along the glacial till cliffs prohibits colonisation of anything but sparse ruderal vegetation. Coltsfoot

24393-456: The other half living in the other 160 parishes. In comparison, Hull's population according to the same census was 243,589. The population density of the district was around 135 people per square km, which made it the least densely populated unitary authority after the Isles of Scilly , Rutland and Herefordshire . The East Riding has a larger than average number of residents aged 40 and above. There

24566-487: The parliament of Edward I , have totally disappeared. The local authorities are endeavouring to prevent the effects of erosion. Hard defences in the form of a concrete seawall and timber groynes have given some protection. It has been suggested that a large underwater reef made of tyres could be built off the Holderness coast to mitigate this erosion, but it would be costly to build. Other defences include sea walls, groynes , and gabions but business people say that if

24739-508: The poles. After the end of the first age, however, temperatures began to increase again, with a number of thermal excursions, such as the middle Valanginian Weissert Thermal Excursion (WTX), which was caused by the Paraná-Etendeka Large Igneous Province's activity. It was followed by the middle Hauterivian Faraoni Thermal Excursion (FTX) and the early Barremian Hauptblatterton Thermal Event (HTE). The HTE marked

24912-520: The power to grind flour on certain days, and natural sites provide interest at Spurn , Bempton Cliffs , Hornsea Mere , Humber Estuary , River Hull , Watton Beck , River Derwent , River Ouse , River Aire , River Trent and River Don , some of which are owned or run by the Yorkshire Wildlife Trust . The Driffield Navigation , Leven Canal , Market Weighton Canal and Pocklington Canal offer glimpses of tranquillity. Stamford Bridge

25085-412: The principal food of mosasaurs , a group of giant marine lizards related to snakes that became extinct at the boundary. Omnivores , insectivores , and carrion -eaters survived the extinction event, perhaps because of the increased availability of their food sources. At the end of the Cretaceous, there seem to have been no purely herbivorous or carnivorous mammals . Mammals and birds that survived

25258-547: The punctuation mark at the end of a progressive decline in biodiversity during the Maastrichtian age. The result was the extinction of three-quarters of Earth's plant and animal species. The impact created the sharp break known as the K–Pg boundary (formerly known as the K–T boundary). Earth's biodiversity required substantial time to recover from this event, despite the probable existence of an abundance of vacant ecological niches . Despite

25431-510: The result that most of these valleys are dry. Surface water is quite scarce throughout the Wolds. At Flamborough Head the Wolds rise up to form high chalk cliffs, where there are water-worn caves and stacks along the shore. Flamborough Headland is designated a Heritage Coast . Coastal erosion around Flamborough Head has led to visitors being warned by the Humber Coastguard to be very careful on coastal paths. The Holderness landscape

25604-744: The rise of angiosperms, during the Jurassic and the Early Cretaceous, the higher flora was dominated by gymnosperm groups, including cycads , conifers , ginkgophytes , gnetophytes and close relatives, as well as the extinct Bennettitales . Other groups of plants included pteridosperms or "seed ferns", a collective term that refers to disparate groups of extinct seed plants with fern-like foliage, including groups such as Corystospermaceae and Caytoniales . The exact origins of angiosperms are uncertain, although molecular evidence suggests that they are not closely related to any living group of gymnosperms. The earliest widely accepted evidence of flowering plants are monosulcate (single-grooved) pollen grains from

25777-601: The river becomes tidal and saline. In the lower reaches it is enclosed by flood banks with little associated natural habitat remaining. The majority of the formerly extensive wetlands have been subject to drainage schemes and agricultural improvement. However some small remnants remain along the Hull valley between Driffield and Wansford . Plants that are typical of these habitats including a variety of reeds, rushes and sedges as well as yellow flag , valerian and meadowsweet may be found. There are few surviving areas of woodland among

25950-418: The same boundaries as the historic riding. It also acted as the ceremonial county (Lieutenancy) area established for the area. At the same date a separate county borough of Kingston upon Hull , was created. The East Riding County Council and the county borough of Kingston upon Hull remained in place for eighty-six years until being removed for new administrative tiers of local government. In 1974 under

26123-447: The severity of the K-Pg extinction event, there were significant variations in the rate of extinction between and within different clades . Species that depended on photosynthesis declined or became extinct as atmospheric particles blocked solar energy . As is the case today, photosynthesizing organisms, such as phytoplankton and land plants , formed the primary part of the food chain in

26296-409: The south and forms part of the ceremonial county area. Other councils areas adjacent to the unitary authority include North East Lincolnshire , beyond the Humber Estuary; North Lincolnshire , beyond the Humber and on land; Hull, Doncaster , North Yorkshire and York . Geologically the East Riding district is split into three parts. The western part is the eastern section of the Vale of York with

26469-412: The south-west corner of Holderness and Bridlington borders the north-east but both are usually considered separately. The main towns include Withernsea , Hornsea and Hedon . The Holderness coast stretches from Flamborough Head to Spurn Head . The ancient market town of Beverley lies just to the west of the Holderness area, on the eastern slopes of the Yorkshire Wolds . Because of its soft soil,

26642-707: The south-west is part of the Humberhead Levels . When the last glacial period ended, the hunter gatherers of the Palaeolithic period followed the animal herds across the land between continental Europe and Britain. Then, as conditions continued to improve and vegetation could support a greater diversity of animals, the annual range of seasonal movement by Mesolithic communities decreased, and people became more fixed to particular localities. Until about 6000 BC, Mesolithic people appear to have exploited their environment as they found it. As communities came to rely on

26815-545: The south-west. Animal husbandry, particularly pig rearing, is a major part of the agricultural scene. In 2001 agriculture employed 4.5% of the working population. Industrial activity ranges from small workshop units in Hornsea and Withernsea to the Easington and Dimlington gas terminals on the east coast. These terminals process gas from the North Sea gas fields. The British Petroleum chemical works at Saltend uses condensates from

26988-442: The southern extension into the Humberhead Levels . In this area there is a belt of sandstones overlain by glacial and lake deposits formed at the close of the last ice age. The middle part is the Yorkshire Wolds , a chalk formation which extends from the Humber at North Ferriby to the coast at Flamborough Head , a chalk headland . The south-east of the district is the low-lying coastal plain of Holderness , which faces east to

27161-554: The spring of 1469. The uprising led by Robin of Redesdale provided the opportunity for Robin of Holderness to lead a separate rebellion relating to a corn tax. Both men submitted to Edward IV <genealogy.com user 1998> in March 1470 following the failure of Warwick's rebellion. Large estates in Holderness were held by the Bishop of Durham and the Archbishop of York . Other large landowners in

27334-422: The strong regionality of most biostratigraphic markers, and the lack of any chemostratigraphic events, such as isotope excursions (large sudden changes in ratios of isotopes ) that could be used to define or correlate a boundary. Calpionellids , an enigmatic group of planktonic protists with urn-shaped calcitic tests briefly abundant during the latest Jurassic to earliest Cretaceous, have been suggested as

27507-611: The terrestrial fauna of the late Cretaceous Hell Creek Formation . Other important Cretaceous exposures occur in Europe (e.g., the Weald ) and China (the Yixian Formation ). In the area that is now India, massive lava beds called the Deccan Traps were erupted in the very late Cretaceous and early Paleocene. Palynological evidence indicates the Cretaceous climate had three broad phases:

27680-483: The trunk having a preserved diameter of 1.8 metres (5.9 ft) and an estimated height of 50 metres (160 ft). During the Cretaceous, ferns in the order Polypodiales , which make up 80% of living fern species, would also begin to diversify. On land, mammals were generally small sized, but a very relevant component of the fauna , with cimolodont multituberculates outnumbering dinosaurs in some sites. Neither true marsupials nor placentals existed until

27853-490: The ultimate end of the Tithonian-early Barremian Cool Interval (TEBCI). During this interval, precession was the dominant orbital driver of environmental changes in the Vocontian Basin. For much of the TEBCI, northern Gondwana experienced a monsoonal climate. A shallow thermocline existed in the mid-latitude Tethys. The TEBCI was followed by the Barremian-Aptian Warm Interval (BAWI). This hot climatic interval coincides with Manihiki and Ontong Java Plateau volcanism and with

28026-413: The upper Cretaceous of Western Europe . The name Cretaceous was derived from the Latin creta , meaning chalk . The twofold division of the Cretaceous was implemented by Conybeare and Phillips in 1822. Alcide d'Orbigny in 1840 divided the French Cretaceous into five étages (stages): the Neocomian , Aptian, Albian, Turonian, and Senonian, later adding the Urgonian between Neocomian and Aptian and

28199-628: The very end, but a variety of non-marsupial metatherians and non-placental eutherians had already begun to diversify greatly, ranging as carnivores ( Deltatheroida ), aquatic foragers ( Stagodontidae ) and herbivores ( Schowalteria , Zhelestidae ). Various "archaic" groups like eutriconodonts were common in the Early Cretaceous, but by the Late Cretaceous northern mammalian faunas were dominated by multituberculates and therians , with dryolestoids dominating South America . The apex predators were archosaurian reptiles , especially dinosaurs , which were at their most diverse stage. Avians such as

28372-436: The west across the River Ouse is the West Riding of Yorkshire . In terms of neighbouring local government administration, the East Riding of Yorkshire unitary authority adjoins North Yorkshire to the north, north-west and to the west, South Yorkshire metropolitan area to the south-west and Lincolnshire across the Humber Estuary to the south. The City of Kingston upon Hull is a separate unitary authority immediately to

28545-407: The world, alternative local subdivisions are still in use. From youngest to oldest, the subdivisions of the Cretaceous period are: The lower boundary of the Cretaceous is currently undefined, and the Jurassic–Cretaceous boundary is currently the only system boundary to lack a defined Global Boundary Stratotype Section and Point (GSSP). Placing a GSSP for this boundary has been difficult because of

28718-417: Was 97.4% white, compared with the English average of 81.0%. The area has a slightly higher elderly population, of 26.4% in 2021, than the national average. By population, the largest settlements in the ceremonial county are: Kingston upon Hull is administered separately from the East Riding of Yorkshire. Anlaby and Willerby are suburban villages, almost contiguous with the Hull urban area. Bridlington

28891-495: Was abolished on 1 April 1996. The area north of the Humber Estuary (i.e. the city of Hull, whose boundaries would remain unchanged, the former districts of East Yorkshire , Beverley , and Holderness , and the northern part of the former Boothferry district, including the Goole area) formed two unitary authorities . The East Riding of Yorkshire Council unitary authority and the Kingston upon Hull City Council unitary authority were formed on 1 April 1996. The ceremonial county,

29064-407: Was also practiced. The area became the kingdom of the tribe known as the Parisi . After invading Britain in AD 43, the Romans crossed the Humber Estuary in AD 71 to invade the Parisi tribe's territory. From their bridgehead at Petuaria they travelled northwards and built roads along the Wolds to Derventio, present-day Malton , and then westwards to the River Ouse where they built

29237-521: Was divided first into three ridings and then into numerous wapentakes within each riding. The separate Lieutenancy for the riding was established after the Restoration , and the ridings each had separate Quarter Sessions . For statistical purposes in the 19th century an East Riding of Yorkshire registration county was designated, consisting of the entirety of the Poor Law Unions of Beverley, Bridlington, Driffield, Howden, Hull , Patrington, Pocklington, Sculcoates, Skirlaugh and York. In 1889 under

29410-450: Was followed by the Aptian-Albian Cold Snap (AACS) that began about 118 Ma. A short, relatively minor ice age may have occurred during this so-called "cold snap", as evidenced by glacial dropstones in the western parts of the Tethys Ocean and the expansion of calcareous nannofossils that dwelt in cold water into lower latitudes. The AACS is associated with an arid period in the Iberian Peninsula . Temperatures increased drastically after

29583-482: Was in 2001 was 1.25 persons per hectare and 78% of households were privately owned compared with a national average of 68%. There was a relatively low unemployment rate of 1.7% compared with a national average of 2.3%. In Holderness the average household income in 2004 was £27,958 compared with a national average of £30,081. The area provides adequate shopping and market facilities for its residents and visitors. The three small towns of Hedon, Hornsea and Withernsea offer

29756-557: Was taken from him when he rebelled against the King William II in 1095. It was returned to her son Stephen of Aumale in 1102. The Honour or Lordship of Holderness then descended to successive Earls (or Counts) of Aumale : William de Forz, 4th Earl, was survived by his widow Isabella de Forz . She was given custody of her children Thomas and William, but outlived them and also her daughter Aveline , who married Edmund Crouchback, 1st Earl of Lancaster (son of Henry III ), but died aged 15. The Honour of Holderness then escheated to

29929-414: Was the first to cross the Wolds in 1853. Holidaymakers on the rail network expanded the coastal resorts of Bridlington, Hornsea and Withernsea . These routes also served the agricultural community in helping to get products to the expanding industrial markets to the port of Hull for export and the West Riding of Yorkshire for further production. The landscape in the East Riding has changed little since
