The Early Jurassic Epoch (in chronostratigraphy corresponding to the Lower Jurassic Series ) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic–Jurassic extinction event , 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.7 ±0.8 Ma.

91-661: The subfamily Dactylioceratinae comprises early Jurassic ammonite genera that lived during Upper Pliensbachian to Upper Toarcian stage. These dactylioceratids existed from Margaritatus ammonite Zone, when they have evolved from Reynesocoeloceratinae and died out in Variabilis Zone without leaving any descendants. While ribs can be single, they are mostly bifurcating at ventrolateral edge and in some genera, even fibulation (primary ribs are joining at ventrolateral tubercules) can exist. Tubercules might also be present at ventrolateral edge, but not in all species. Final aperture

182-446: A chamber containing dried ink inside a belemnite fossil. She showed it to her friend Elizabeth Philpot who was able to revivify the ink and use it to illustrate some of her own ichthyosaur fossils. Soon other local artists were doing the same, as more such fossilised ink chambers were discovered. Anning noted how closely the fossilised chambers resembled the ink sacs of modern squid and cuttlefish , which she had dissected to understand

273-452: A contemporary newspaper article called an unrivalled specimen of Dapedium politum . This was a ray-finned fish, which would be described in 1828. In December of that same year she made an important find consisting of the partial skeleton of a pterosaur . In 1829 William Buckland described it as Pterodactylus macronyx (later renamed Dimorphodon macronyx by Richard Owen), and unlike many other such occasions, Buckland credited Anning with

364-409: A direct cast of the fossil, but are determined to be of good condition, "historically important", and likely taken from the specimen put for sale at auction by Anning in 1820. In the same 1821 paper he co-authored with Henry De la Beche on ichthyosaur anatomy, William Conybeare named and described the genus Plesiosaurus (near lizard), called so because he thought it more like modern reptiles than

455-481: A drinking problem. The regard in which Anning was held by the geological community was shown in 1846 when, upon learning of her cancer diagnosis, the Geological Society raised money from its members to help with her expenses and the council of the newly created Dorset County Museum made Anning an honorary member. She was buried on 15 March in the churchyard of St Michael's , the local parish church. Members of

546-531: A fall off a cliff, contributing to his death in November 1810 (aged 44). He left the family with debts and no savings, forcing them to apply for poor relief . The family continued collecting and selling fossils together and set up a table of curiosities near the coach stop at a local inn. Although the stories about Anning tend to focus on her successes, Dennis Dean writes that her mother and brother were astute collectors too, and Anning's parents had sold fossils before

637-549: A few weeks to "become a good practical fossilist, by working with the celebrated Mary Anning of that place...". Charlotte and Anning became lifelong friends and correspondents. Charlotte, who travelled widely and met many prominent geologists through her work with her husband, helped Anning build her network of customers throughout Europe, and she stayed with the Murchisons when she visited London in 1829. Anning's correspondents included Charles Lyell , who wrote to ask her opinion on how

728-415: A previously unknown type of marine reptile, and based on differences in tooth structure, they concluded that there had been at least three species. Also in 1821, Anning found the 20 ft (6.1 m) skeleton from which the species Ichthyosaurus platydon (now Temnodontosaurus platyodon ) would be named. In the 1980s it was determined that the first ichthyosaur specimen found by Joseph and Mary Anning

819-634: A problem that makes correlation between sections in different parts of the world difficult. If this biostratigraphical indicator is used, then technically the Lias Group —a lithostratigraphical division—spans the Jurassic / Triassic boundary. There are extensive Liassic outcrops around the coast of the United Kingdom , in particular in Glamorgan , North Yorkshire and Dorset . The 'Jurassic Coast' of Dorset

910-551: A shallow seabed early in the Jurassic period (about 210–195 million years ago). It is one of the richest fossil locations in Britain. The cliffs could be dangerously unstable, however, especially in winter when rain weakened them, causing landslides. It was precisely during the winter months that collectors were drawn to the cliffs because the landslides often exposed new fossils. Their father, Richard, often took Anning and her brother Joseph on fossil-hunting expeditions to supplement

1001-454: A travelling company of horsemen when lightning struck the tree—killing all three women below. Onlookers rushed the infant home, where she was revived in a bath of hot water. A local doctor declared her survival miraculous. Anning's family said she had been a sickly baby before the event, but afterwards she seemed to blossom. For years afterwards, members of her community would attribute the child's curiosity, intelligence and lively personality to

1092-624: A well-known collector, who displayed it in London . There it generated interest, as public awareness of the age of the Earth and the variety of prehistoric creatures was growing. It was later sold for £45 and five shillings at auction in May 1819 as a "Crocodile in a Fossil State" to Charles Konig , of the British Museum , who had already suggested the name Ichthyosaurus for it. Anning's mother Molly initially ran

1183-588: A woman, she was not eligible to join the Geological Society of London , and she did not always receive full credit for her scientific contributions. However, her friend, geologist Henry De la Beche , who painted Duria Antiquior , the first widely circulated pictorial representation of a scene from prehistoric life derived from fossil reconstructions, based it largely on fossils Anning had found and sold prints of it for her benefit. Anning became well known in geological circles in Britain, Europe, and America, and

1274-432: A woman. These were honours normally only accorded to fellows of the society, which did not admit women until 1904. The eulogy began: I cannot close this notice of our losses by death without adverting to that of one, who though not placed among even the easier classes of society, but one who had to earn her daily bread by her labour, yet contributed by her talents and untiring researches in no small degree to our knowledge of

1365-693: Is contracted. Size dimorphism is common. Taxonomic composition of this subfamily differs among literature. Well known is taxonomy according to Treatise on Invertebrate Paleontology , which is shown below with addition of Tokurites , which has not been known in the time, when current edition of Treatise has been published. Some scholars consider Nodicoeloceratinae as valid taxon and not as synonym of Dactylioceratinae. In their view, some of aforementioned genera does not belong to Dactylioceratinae. These are Nodicoeloceras , Collina and some genera, which are by other scholars considered to be synonyms with Nodicoeloceras , Catacoeloceras and Porpoceras . On

1456-570: Is not clear whether the man ran off with the money or whether he died suddenly leaving Anning with no way to recover the investment. Concerned about Anning's financial situation, her old friend William Buckland persuaded the British Association for the Advancement of Science and the British government to award her an annuity , known as a civil list pension , in return for her many contributions to

1547-513: Is often associated with the pioneering work of Mary Anning of Lyme Regis . The facies of the Lower Jurassic in this area are predominantly of clays , thin limestones and siltstones , deposited under fully marine conditions. Lias Group strata form imposing cliffs on the Vale of Glamorgan coast, in southern Wales . Stretching for around 14 miles (23 km) between Cardiff and Porthcawl ,

1638-530: Is probably paraphyletic ). All these plesiosaurs had medium-sized necks and large heads. In the Toarcian , at the end of the Early Jurassic, the thalattosuchians (marine " crocodiles ") appeared, as did new genera of ichthyosaurs ( Stenopterygius , Eurhinosaurus , and the persistently primitive Suevoleviathan ) and plesiosaurs (the elasmosaurs (long-necked) Microcleidus and Occitanosaurus , and

1729-428: Is that she has made herself so thoroughly acquainted with the science that the moment she finds any bones she knows to what tribe they belong. She fixes the bones on a frame with cement and then makes drawings and has them engraved... It is certainly a wonderful instance of divine favour—that this poor, ignorant girl should be so blessed, for by reading and application she has arrived to that degree of knowledge as to be in

1820-613: The Magazine of Natural History to question the claim made in an article, that a recently discovered fossil of the prehistoric shark Hybodus represented a new genus, as an error since she had discovered the existence of fossil sharks with both straight and hooked teeth many years ago. The extract from the letter that the magazine printed was the only writing of Anning's published in the scientific literature during her lifetime. Some personal letters written by Anning, such as her correspondence with Frances Augusta Bell , were published while she

1911-513: The pliosaur Hauffiosaurus ). On land, a number of new types of dinosaurs—the heterodontosaurids , scelidosaurs , stegosaurs , and tetanurans —appeared, and joined those groups like the coelophysoids , prosauropods and the sauropods that had continued over from the Triassic. Accompanying them as small carnivores were the sphenosuchian and protosuchid crocodilians. In the air, new types of pterosaurs replaced those that had died out at

2002-631: The Anglican church. The change was prompted in part by a decline in Congregational attendance that began in 1828 when its popular pastor, John Gleed, a fellow fossil collector, left for the United States to campaign against slavery. He was replaced by the less likeable Ebenezer Smith. The greater social respectability of the established church, in which some of Anning's gentleman geologist customers such as Buckland, Conybeare, and Sedgwick were ordained clergy,

2093-576: The British Museum, had already suggested the name Ichthyosaurus (fish lizard) for the specimen and that name stuck. Konig purchased the skeleton for the museum in 1819. The skull of the specimen is still in the possession of the Natural History Museum in London (to which the fossil collections of the British Museum were transferred later in the century), but at some point, it became separated from

2184-458: The Geological Society contributed to a stained-glass window in Anning's memory, unveiled in 1850. It depicts the six corporal acts of mercy —feeding the hungry, giving drink to the thirsty, clothing the naked, sheltering the homeless, visiting prisoners and the sick, and the inscription reads: "This window is sacred to the memory of Mary Anning of this parish, who died 9 March AD 1847 and is erected by

2275-425: The Geological Society in 1824, he again failed to mention Anning by name, even though she had possibly collected both skeletons and had made the sketch of the second skeleton he used in his presentation. Conybeare's presentation was made at the same meeting at which William Buckland described the dinosaur Megalosaurus and the combination created a sensation in scientific circles. Conybeare's presentation followed

2366-1067: The Reverend James Wheaton, had published two essays, one insisting that God had created the world in six days, the other urging dissenters to study the new science of geology. By the late 18th century, Lyme Regis had become a popular seaside resort, especially after 1792 when the outbreak of the French Revolutionary Wars made travel to the European mainland dangerous for the English gentry, and increasing numbers of wealthy and middle-class tourists were arriving there. Even before Anning's time, locals supplemented their income by selling what were called "curios" to visitors. These were fossils with colourful local names such as "snake-stones" ( ammonites ), "devil's fingers" ( belemnites ), and "verteberries" ( vertebrae ), to which were sometimes attributed medicinal and mystical properties. Fossil collecting

2457-465: The University of Oxford, often visited Lyme on his Christmas vacations and was frequently seen hunting for fossils with Anning. It was to him Anning made what would prove to be the scientifically important suggestion (in a letter auctioned for over £100,000 in 2020 ) that the strange conical objects known as bezoar stones were really the fossilised faeces of ichthyosaurs or plesiosaurs. Buckland would name

2548-689: The acidic Devonian and Carboniferous soils of the West Country ); the Cornish would pronounce the layers of limestone as ' laiyers ' or ' lias '; leac is Gaelic for "flat stone". There has been some debate over the actual base of the Hettangian Stage, and so of the Jurassic System itself. Biostratigraphically , the first appearance of psiloceratid ammonites has been used; but this depends on relatively complete ammonite faunas being present,

2639-507: The anatomy of fossil cephalopods , and this led William Buckland to publish the conclusion that Jurassic belemnites had used ink for defence just as many modern cephalopods do. It was also Anning who noticed that the oddly shaped fossils then known as "bezoar stones" were sometimes found in the abdominal region of ichthyosaur skeletons. She noted that if such stones were broken open they often contained fossilised fish bones and scales, and sometimes bones from small ichthyosaurs. Anning suspected

2730-436: The author, noting that Fagan's work was "neither original nor reliable" and "introduced errors into the Anning literature which are still problematic." Specifically, they noted that Fagan had largely and inaccurately plagiarised his article from an earlier account of Anning's life and work by Dorset native Henry Rowland Brown , from the second edition of Brown's 1859 guidebook, The Beauties of Lyme Regis. The article emphasised

2821-444: The carriage and were proceeding on foot, when we fell in with a shop in which the most remarkable petrifications and fossil remains—the head of an Ichthyosaurus —beautiful ammonites, etc. were exhibited in the window. We entered and found the small shop and adjoining chamber completely filled with fossil productions of the coast ... I found in the shop a large slab of blackish clay, in which a perfect Ichthyosaurus of at least six feet,

2912-521: The children born in the UK in the 19th century died before the age of five, and in the crowded living conditions of early 19th-century Lyme Regis, infant deaths from diseases like smallpox and measles were common. On 19 August 1800, when Anning was 15 months old, an event occurred that became part of local lore. She was being held by a neighbour, Elizabeth Haskings, who was standing with two other women under an elm tree watching an equestrian show being put on by

3003-404: The cliff that fell upon him and killed him in a moment before my eyes, and close to my feet ... it was but a moment between me and the same fate." As Anning continued to make important finds, her reputation grew. On 10 December 1823, she found the first complete Plesiosaurus , and in 1828 the first British example of the flying reptiles known as pterosaurs , called a flying dragon when it

3094-501: The cliffs along the English Channel at Lyme Regis in the county of Dorset , Southwest England . Anning's findings contributed to changes in scientific thinking about prehistoric life and the history of the Earth . Anning searched for fossils in the area's Blue Lias and Charmouth Mudstone cliffs, particularly during the winter months when landslides exposed new fossils that had to be collected quickly before they were lost to

3185-716: The contributions of working-class people in early 19th-century scientific literature. Often a fossil would be found by a quarryman, construction worker, or road worker who would sell it to a wealthy collector, and it was the latter who was credited if the find was of scientific interest. Along with purchasing specimens, many geologists visited Anning to collect fossils or discuss anatomy and classification. Henry De la Beche and Anning became friends as teenagers following his move to Lyme, and he, Anning, and sometimes her brother Joseph, went fossil-hunting together. De la Beche and Anning kept in touch as he became one of Britain's leading geologists. William Buckland , who lectured on geology at

3276-438: The difficulties Anning had overcome, especially the scepticism of her fellow townspeople. Fagan ended the article with: "The carpenter's daughter has won a name for herself, and has deserved to win it." Anning's first famous discovery was made shortly after her father's death when she was still a child of about 12. In 1811 (some sources say 1810 or 1809) her brother Joseph found a 4 ft (1.2 m) skull, but failed to locate

3367-629: The discovery in his paper. It was the first pterosaur skeleton found outside Germany, and it created a public sensation when displayed at the British Museum. Recent research has found that these creatures were not inclined to fly continuously in their search for fish. In December 1829 she found a fossil fish, Squaloraja , which attracted attention because it had characteristics intermediate between sharks and rays . Vertebrate fossil finds, especially of marine reptiles , made Anning's reputation, but she made numerous other contributions to early palaeontology. In 1826 Anning discovered what appeared to be

3458-461: The end of the Triassic. But in the undergrowth were various types of early mammals, as well as tritylodont synapsids , lizard-like sphenodonts , and early lissamphibians . Mary Anning Mary Anning (21 May 1799 – 9 March 1847) was an English fossil collector , dealer , and palaeontologist . She became known internationally for her discoveries in Jurassic marine fossil beds in

3549-518: The family lived so near to the sea that the same storms that swept along the cliffs to reveal the fossils sometimes flooded the Annings' home, on one occasion forcing them to crawl out of an upstairs bedroom window to avoid drowning. Molly and Richard had ten children. The first child, also Mary, was born in 1794. She was followed by another daughter, who died almost at once; Joseph in 1796; and another son in 1798, who died in infancy. In December that year,

3640-522: The family's income. They offered their discoveries for sale to tourists on a table outside their home. This was a difficult time for England's poor; the French Revolutionary Wars , and the Napoleonic Wars that followed, caused food shortages. The price of wheat almost tripled between 1792 and 1812, but wages for the working class remained almost unchanged. In Dorset, the rising price of bread caused political unrest, even riots. At one point, Richard Anning

3731-469: The father's death. Their first well-known find was in 1811 when Mary Anning was 12; her brother Joseph dug up a 4-foot ichthyosaur skull, and a few months later Anning herself found the rest of the skeleton. Henry Hoste Henley of Sandringham House in Sandringham, Norfolk , who was lord of the manor of Colway, near Lyme Regis, paid the family about £23 for it, and in turn he sold it to William Bullock ,

3822-457: The find raised questions in scientific and religious circles about what the new science of geology was revealing about ancient life and the history of the Earth. Its notoriety increased when Sir Everard Home wrote a series of six papers, starting in 1814, describing it for the Royal Society. The papers never mentioned who had collected the fossil, and in the first one he even mistakenly credited

3913-407: The fossil business after her husband Richard's death, but it is unclear how much actual fossil collecting Molly did herself. As late as 1821, Molly wrote to the British Museum to request payment for a specimen. Her son Joseph's time was increasingly taken up by his apprenticeship to an upholsterer , but he remained active in the fossil business until at least 1825. By that time, Mary Anning had assumed

4004-399: The fossils he had purchased from them. He wrote to the palaeontologist Gideon Mantell on 5 March that year to say that the sale was "for the benefit of the poor woman and her son and daughter at Lyme, who have in truth found almost all the fine things which have been submitted to scientific investigation ... I may never again possess what I am about to part with, yet in doing it I shall have

4095-624: The geological community. Anning continued to support herself selling fossils. Her primary stock in trade consisted of invertebrate fossils such as ammonite and belemnite shells, which were common in the area and sold for a few shillings. Vertebrate fossils, such as ichthyosaur skeletons, sold for more, but were much rarer. Collecting them was dangerous winter work. In 1823, an article in The Bristol Mirror said of her: This persevering female has for years gone daily in search of fossil remains of importance at every tide, for many miles under

4186-606: The great Enalio-Saurians , and other forms of organic life entombed in the vicinity of Lyme Regis ... An anonymous article about Anning's life was published in February 1865 in Charles Dickens 's literary magazine All the Year Round . The profile, "Mary Anning, The Fossil Finder," was long attributed to Dickens himself but, in 2014, historians of palaeontology Michael A. Taylor and Hugh S. Torrens identified Henry Stuart Fagan as

4277-465: The great collections ... The risks of Anning's profession were illustrated when in October 1833 she barely avoided being killed by a landslide that buried her black-and-white terrier, Tray, her constant companion when she went collecting. Anning wrote to a friend, Charlotte Murchison , in November of that year: "Perhaps you will laugh when I say that the death of my old faithful dog has quite upset me,

4368-402: The habit of writing and talking with professors and other clever men on the subject, and they all acknowledge that she understands more of the science than anyone else in this kingdom. In 1826, aged 27, Anning managed to save enough money to purchase a house with a glass store-front window for her shop, Anning's Fossil Depot . The business had become important enough that the move was covered in

4459-418: The hanging cliffs at Lyme, whose fallen masses are her immediate object, as they alone contain these valuable relics of a former world, which must be snatched at the moment of their fall, at the continual risk of being crushed by the half suspended fragments they leave behind, or be left to be destroyed by the returning tide: – to her exertions we owe nearly all the fine specimens of Ichthyosauri of

4550-479: The ichthyosaur had been. The description was based on a number of fossils, the most complete of them specimen OUMNH J.50146, a paddle and vertebral column that had been obtained by Lieutenant-Colonel Thomas James Birch. Christopher McGowan has hypothesised that this specimen had originally been much more complete and had been collected by Anning, during the winter of 1820/1821. If so, it would have been Anning's next major discovery, providing essential information about

4641-517: The incident. Anning's education was extremely limited, but she was able to attend a Congregationalist Sunday school , where she learned to read and write. Congregationalist doctrine, unlike that of the Church of England at the time, emphasised the importance of education for the poor. Her prized possession was a bound volume of the Dissenters' Theological Magazine and Review , in which the family's pastor,

4732-437: The leading role in the family specimen business. The family's keenest customer was Lieutenant-Colonel Thomas James Birch, later Bosvile, a wealthy collector from Lincolnshire , who bought several specimens from them. In 1820 Birch became disturbed by the family's poverty. Having made no major discoveries for a year, they were at the point of having to sell their furniture to pay the rent. So he decided to auction on their behalf

4823-625: The local paper, which noted that the shop had a fine ichthyosaur skeleton on display. Many geologists and fossil collectors from Europe and America visited her at Lyme, including the geologist George William Featherstonhaugh , who called Anning a "very clever funny Creature." He purchased fossils from Anning for the newly opened New York Lyceum of Natural History in 1827. King Frederick Augustus II of Saxony visited her shop in 1844 and purchased an ichthyosaur skeleton for his extensive natural history collection. The king's physician and aide, Carl Gustav Carus , wrote in his journal: We had alighted from

4914-610: The mystery. Anning's discoveries became key pieces of evidence for extinction . Georges Cuvier had argued for the reality of extinction in the late 1790s based on his analysis of fossils of mammals such as mammoths . Nevertheless, until the early 1820s it was still believed by many scientifically literate people that just as new species did not appear, so existing ones did not become extinct—in part because they felt that extinction would imply that God's creation had been imperfect; any oddities found were explained away as belonging to animals still living somewhere in an unexplored region of

5005-548: The name Lias: the first reason is it was taken by a geologist from an English quarryman 's dialect pronunciation of the word "layers"; secondly, sloops from north Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias and Carboniferous limestone from South Wales was used throughout North Devon/North Cornwall as it contains calcium carbonate to 'sweeten' (i.e.neutralise)

5096-417: The newly opened factories. Although Anning knew more about fossils and geology than many of the wealthy fossilists to whom she sold, it was always the gentlemen geologists who published the scientific descriptions of the specimens she found, often neglecting to mention Anning's name. She became resentful of this. Anna Pinney, a young woman who sometimes accompanied Anning while she collected, wrote: "She says

5187-405: The newly recognised type of marine reptile. No records by Anning of the find are known. The paper thanked Birch for giving Conybeare access to it, but does not mention who discovered and prepared it. In 1823, Anning discovered a second, much more complete plesiosaur skeleton, specimen NHMUK OR 22656 (formerly BMNH 22656). When Conybeare presented his analysis of plesiosaur anatomy to a meeting of

5278-502: The objects coprolites . In 1839 Buckland, Conybeare, and Richard Owen visited Lyme together so that Anning could lead them all on a fossil-collecting excursion. Anning also assisted Thomas Hawkins with his efforts to collect ichthyosaur fossils at Lyme in the 1830s. She was aware of his penchant to "enhance" the fossils he collected. Anning wrote: "he is such an enthusiast that he makes things as he imagines they ought to be; and not as they are really found...". A few years later there

5369-473: The oldest child, (the first Mary) then four years old, died after her clothes caught fire, possibly while adding wood shavings to the fire. The incident was reported in the Bath Chronicle on 27 December 1798: "A child, four years of age of Mr. R. Anning, a cabinetmaker of Lyme, was left by the mother for about five minutes ... in a room where there were some shavings ... The girl's clothes caught fire and she

You can help Misplaced Pages by expanding it . Early Jurassic Certain rocks of marine origin of this age in Europe are called " Lias " and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic . There are two possible origins for

5551-545: The painstaking cleaning and preparation of the fossil performed by Anning to the staff at Bullock's museum. Perplexed by the creature, Home kept changing his mind about its classification, first thinking it was a kind of fish, then thinking it might have some kind of affinity with the duck-billed platypus (only recently known to science); finally in 1819 he reasoned it might be a kind of intermediate form between salamanders and lizards, which led him to propose naming it Proteo-Saurus. By then Charles Konig, an assistant curator of

5642-435: The proceeds to Anning. It became the first such scene from what later became known as deep time to be widely circulated. In December 1830, Anning finally made another major find, a skeleton of a new type of plesiosaur, which sold for £200. It was around this time that Anning switched from attending the local Congregational church, where she had been baptised and in which she and her family had always been active members, to

5733-612: The remarkable layers of these cliffs, situated on the Bristol Channel are a rhythmic decimetre scale repetition of limestone and mudstone formed as a late Triassic desert was inundated by the sea. During this period, ammonoids , which had almost died out at the end-of-Triassic extinction, radiated out into a huge diversity of new forms with complex suture patterns (the ammonites proper). Ammonites evolved so rapidly, and their shells are so often preserved, that they serve as important zone fossils . There were several distinct waves of ammonite evolution in Europe alone. The Early Jurassic

5824-431: The resolution of a controversy over the legitimacy of one of the fossils. The fact that the plesiosaur's long neck had an unprecedented 35 vertebrae raised the suspicions of the eminent French anatomist Georges Cuvier when he reviewed Anning's drawings of the second skeleton, and he wrote to Conybeare suggesting the possibility that the find was a fake produced by combining fossil bones from different kinds of animals. Fraud

5915-431: The rest of the animal. After Joseph told Anning to look between the cliffs at Lyme Regis and Charmouth, she found the skeleton—17 ft (5.2 m) long in all—a few months later. The family hired workmen to dig it out in November that year, an event covered by the local press on 9 November, who identified the fossil as a crocodile. Other ichthyosaur remains had been discovered in years past at Lyme and elsewhere, but

6006-418: The rest of the skeleton, the location of which is not known. Anning found several other ichthyosaur fossils between 1815 and 1819, including almost complete skeletons of varying sizes. In 1821, William Conybeare and Henry De la Beche, both members of the Geological Society of London, collaborated on a paper that analysed in detail the specimens found by Anning and others. They concluded that ichthyosaurs were

6097-409: The satisfaction of knowing that the money will be well applied." The auction was held at Bullocks in London on 15 May 1820, and raised £400 (the equivalent of £40,000 in 2024). How much of that was given to the Annings is not known, but it seems to have placed the family on a steadier financial footing, and with buyers arriving from Paris and Vienna, the three-day event raised the family's profile within

6188-455: The science of geology. The £25 annual pension gave Anning some financial security. Anning died from breast cancer at the age of 47 on 9 March 1847. Her fossil work had tailed off during the last few years of her life because of her illness, and as some townspeople misinterpreted the effects of the increasing doses of laudanum she was taking for the pain, there had been gossip in Lyme that she had

6279-457: The sea was affecting the coastal cliffs around Lyme, as well as Adam Sedgwick —one of her earliest customers—who taught geology at the University of Cambridge and who numbered Charles Darwin among his students. Gideon Mantell , discoverer of the dinosaur Iguanodon , also visited Anning at her shop. By 1830, because of difficult economic conditions in Britain that reduced the demand for fossils, coupled with long gaps between major finds, Anning

6370-554: The sea. Her discoveries included the first correctly identified ichthyosaur skeleton when she was twelve years old; the first two nearly complete plesiosaur skeletons; the first pterosaur skeleton located outside Germany; and fish fossils. Her observations played a key role in the discovery that coprolites , known as bezoar stones at the time, were fossilised faeces , and she also discovered that belemnite fossils contained fossilised ink sacs like those of modern cephalopods . Anning struggled financially for much of her life. As

6461-443: The specimen found by the Annings was the first to come to the attention of scientific circles in London. It was purchased by the lord of a local manor, who passed it to William Bullock for public display in London where it created a sensation. At a time when most people in Britain still believed in a literal interpretation of Genesis , that the Earth was only a few thousand years old and that species did not evolve or become extinct,

6552-499: The stones were fossilised faeces and suggested so to Buckland in 1824. After further investigation and comparison with similar fossils found in other places, Buckland published that conclusion in 1829 and named them coprolites . In contrast to the finding of the plesiosaur skeletons a few years earlier, for which she was not credited, when Buckland presented his findings on coprolites to the Geological Society, he mentioned Anning by name and praised her skill and industry in helping to solve

6643-409: The vicar and some members of the Geological Society of London in commemoration of her usefulness in furthering the science of geology, as also of her benevolence of heart and integrity of life." After Anning's death, Henry De la Beche, president of the Geological Society, wrote a eulogy that he read to a meeting of the society and published in its quarterly transactions, the first such eulogy given for

6734-404: The world has used her ill ... these men of learning have sucked her brains, and made a great deal of publishing works, of which she furnished the contents, while she derived none of the advantages." Anning herself wrote in a letter: "The world has used me so unkindly, I fear it has made me suspicious of everyone". Torrens writes that these slights to Anning were part of a larger pattern of ignoring

6825-644: Was a cabinetmaker and carpenter who supplemented his income by mining the coastal cliff-side fossil beds near the town, and selling his finds to tourists; her mother was Mary Moore ( c . 1764–1842) known as Molly. Anning's parents married on 8 August 1793 in Blandford Forum and moved to Lyme, living in a house built on the town's bridge. They attended the Dissenter chapel on Coombe Street, whose worshippers initially called themselves independents and later became known as Congregationalists . Shelley Emling writes that

6916-413: Was a public scandal when it was discovered that Hawkins had inserted fake bones to make some ichthyosaur skeletons seem more complete, and later sold them to the government for the British Museum's collection without the appraisers knowing about the additions. The Swiss palaeontologist Louis Agassiz visited Lyme Regis in 1834 and worked with Anning to obtain and study fish fossils found in the region. He

7007-459: Was alive, however. As a woman, Anning was treated as an outsider to the scientific community. At the time in Britain, women were not allowed to vote, hold public office, or attend university. The newly formed, but increasingly influential Geological Society of London did not allow women to become members, or even to attend meetings as guests. The only occupations generally open to working-class women were farm labour, domestic service, and work in

7098-435: Was also a factor. Anning, who was devoutly religious , actively supported her new church as she had her old. Anning suffered another serious financial setback in 1835 when she lost most of her life savings, about £300, in a bad investment. Sources differ somewhat on what exactly went wrong. Deborah Cadbury says that she invested with a conman who swindled her and disappeared with the money, but Shelley Emling writes that it

7189-660: Was also a member of Temnodontosaurus platyodon . In 2022, two plaster casts of the first complete ichthyosaur skeleton fossil found by Anning that was destroyed in the bombing of London during the Second World War, were discovered in separate collections. One is at the Peabody Museum of Natural History at Yale University in the US and the other at the Natural History Museum in Berlin, Germany. The casts may be secondary, being made from

7280-476: Was an important time in the evolution of the marine reptiles. The Hettangian saw the already existing Rhaetian ichthyosaurs and plesiosaurs continuing to flourish, while at the same time a number of new types of these marine reptiles appeared, such as Ichthyosaurus and Temnodontosaurus among the ichthyosaurs, and Eurycleidus , Macroplata , and Rhomaleosaurus among the plesiosaurs (all Rhomaleosauridae , although as currently defined this group

7371-598: Was consulted on issues of anatomy as well as fossil collecting. The only scientific writing of hers published in her lifetime appeared in the Magazine of Natural History in 1839, an extract from a letter that Anning had written to the magazine's editor questioning one of its claims. After her death in 1847, Anning's unusual life story attracted increasing interest. Mary Anning was born in Lyme Regis in Dorset , England, on 21 May 1799. Her father, Richard Anning ( c . 1766–1810),

7462-477: Was displayed at the British Museum, followed by a Squaloraja fish skeleton in 1829. Despite her limited education, she read as much of the scientific literature as she could obtain, and often laboriously hand-copied papers borrowed from others. Palaeontologist Christopher McGowan examined a copy Anning made of an 1824 paper by William Conybeare on marine reptile fossils and noted that the copy included several pages of her detailed technical illustrations that he

7553-548: Was embedded. This specimen would have been a great acquisition for many of the cabinets of natural history on the Continent, and I consider the price demanded, £15 sterling, as very moderate. Carus asked Anning to write her name and address in his pocketbook for future reference—she wrote it as "Mary Annins"—and when she handed it back to him she told him: "I am well known throughout the whole of Europe". As time passed, Anning's confidence in her knowledge grew, and in 1839 she wrote to

7644-431: Was far from unknown among early 19th-century fossil collectors, and if the controversy had not been resolved promptly, the accusation could have seriously damaged Anning's ability to sell fossils to other geologists. Cuvier's accusation had resulted in a special meeting of the Geological Society earlier in 1824, which, after some debate, had concluded the skeleton was legitimate. Cuvier later admitted he had acted in haste and

7735-449: Was hard-pressed to tell apart from the original. She also dissected modern animals including both fish and cuttlefish to gain a better understanding of the anatomy of some of the fossils with which she was working. Lady Harriet Silvester, the widow of the former Recorder of the City of London , visited Lyme in 1824 and described Anning in her diary: The extraordinary thing in this young woman

7826-411: Was having financial problems again. Her friend, the geologist Henry De la Beche, assisted her by commissioning Georg Scharf to make a lithographic print based on De la Beche's watercolour painting, Duria Antiquior , portraying life in prehistoric Dorset that was based largely on fossils Anning had found. De la Beche sold copies of the print to his fellow geologists and other wealthy friends and donated

7917-462: Was in vogue in the late 18th and early 19th century, at first as a pastime, but gradually transforming into a science as the importance of fossils to geology and biology was understood. The source of most of these fossils were the coastal cliffs around Lyme Regis, part of a geological formation known as the Blue Lias . This consists of alternating layers of limestone and shale , laid down as sediment on

8008-632: Was involved in organising a protest against food shortages. In addition, the family's status as religious dissenters—not followers of the Church of England —attracted discrimination. In the earlier nineteenth century, those who refused to subscribe to the Articles of the Church of England were still not allowed to study at Oxford or Cambridge or to take certain positions in the army, and were excluded by law from several professions. Anning's father had been suffering from tuberculosis and injuries he suffered from

8099-462: Was mistaken. Anning discovered yet another important and nearly complete plesiosaur skeleton in 1830. It was named Plesiosaurus macrocephalus by William Buckland and was described in an 1840 paper by Richard Owen . Once again Owen mentioned the wealthy gentleman who had purchased the fossil and made it available for examination, but not the woman who had discovered and prepared it. Anning found what

8190-418: Was so dreadfully burnt as to cause her death." When Anning was born five months later, she was thus named Mary after her dead sister. More children were born after her, but none of them survived more than a year or two. Only the second Mary Anning and her brother Joseph, who was three years older than her, survived to adulthood. The high child mortality rate for the Anning family was not unusual. Almost half

8281-580: Was so impressed by Anning and her friend Elizabeth Philpot that he wrote in his journal: "Miss Philpot and Mary Anning have been able to show me with utter certainty which are the ichthyodorulite's dorsal fins of sharks that correspond to different types." He thanked both of them for their help in his book, Studies of Fossil Fish . Another leading British geologist, Roderick Murchison , did some of his first fieldwork in southwest England, including Lyme, accompanied by his wife, Charlotte . Murchison wrote that they decided Charlotte should stay behind in Lyme for
