The Sannine Formation , also called the Sannine Limestone , is a Cretaceous geologic formation in Lebanon . It is a Konservat-Lagerstätte that contains a high diversity of well-preserved fish, reptiles, and invertebrates from the Tethys Ocean within its three main localities: Haqel (alternatively Hakel or Haqil), Hjoula (alternatively Hadjoula, Hajoula, or Hgula), and Nammoura (alternatively Namoura).

71-459: It is one of three major Cretaceous lagerstätte in Lebanon, alongside the older ( Barremian -aged) Lebanese amber and the younger ( Santonian -aged) Sahel Aalma site. The Sannine Formation localities, combined with Sahel Alma, are together referred to as the "Fish Beds" of Lebanon. It is primarily Cenomanian in age, with Haqel and Hjoula being late Cenomanian, while the slightly older Nammoura site

142-572: A History of the Freshwater Fish of Central Europe . In 1839, however, the first part of the publication appeared, and it was completed in 1842. In November 1832, Agassiz was appointed professor of natural history at the University of Neuchâtel , at a salary of about US$ 400 and declined brilliant offers in Paris because of the leisure for private study that that position afforded him. The fossil fish in

213-570: A PhD at Erlangen and a medical degree in Munich . After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel . He emigrated to the United States in 1847 after visiting Harvard University . He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School , and to found its Museum of Comparative Zoology . Agassiz

Numerous species of fossil fish are known, including the ionoscopid Spathiurus dorsalis and pycnodontid Flagellipinna rhomboides . An incredible diversity of fossil pycnodonts of various, highly unusual body plans is known, in addition to

426-541: A Lebanese fossil fish locality in person was Cornelis de Bruijn in 1698, who illustrated a fossil fish that corresponds with the species Prionolepis cataphractus from Haqel. The first scientific presentation on the fossil fishes of Haqel was in 1703 at the French Academy of Sciences , and the first scientific studies were conducted by Henri Marie Ducrotay de Blainville in 1818. Lady Hester Stanhope collected and circulated fossil fishes from Haqel and Sahel Alma during

497-619: A benefactor to the Boston Museum of Fine Arts . Pauline Agassiz Shaw later became a prominent educator, suffragist, and philanthropist. In the last years of his life, Agassiz worked to establish a permanent school in which zoological science could be pursued amid the living subjects of its study. In 1873, the private philanthropist John Anderson gave Agassiz the island of Penikese , in Buzzards Bay , Massachusetts (south of New Bedford ), and presented him with $ 50,000 to endow it permanently as

568-473: A catalog of papers in his field, Bibliographia Zoologiae et Geologiae , in four volumes between 1848 and 1854. Stricken by ill health in the 1860s, Agassiz resolved to return to the field for relaxation and to resume his studies of Brazilian fish. In April 1865, he led the Thayer Expedition to Brazil. While there, he commissioned two photographers, Augusto Stahl and Georges Leuzinger , to accompany

639-820: A course of lectures on "The Plan of Creation as shown in the Animal Kingdom" by invitation from John Amory Lowell , at the Lowell Institute in Boston , Massachusetts . The financial offers that were presented to him in the United States induced him to settle there, where he remained to the end of his life. He was elected a foreign honorary member of the American Academy of Arts and Sciences in 1846. In 1846, still married to Cecilie, who remained with their three children in Switzerland, Agassiz met Elizabeth Cabot Cary at

710-454: A dinner. The two developed a romantic attachment, and when his wife died in 1848, they made plans to marry. The ceremony took place on April 25, 1850, in Boston, Massachusetts at King's Chapel . Agassiz brought his children to live with them, and Elizabeth raised and developed close relationships with her step-children. She had no children of her own. Agassiz had a mostly cordial relationship with

781-535: A focus of Agassiz's life's work. In 1819 to 1820, the German biologists Johann Baptist von Spix and Carl Friedrich Philipp von Martius undertook an expedition to Brazil . They returned home to Europe with many natural objects, including an important collection of the freshwater fish of Brazil, especially of the Amazon River . Spix, who died in 1826, likely from a tropical disease, did not live long enough to work out

852-590: A new ichthyological classification. The fossils that he examined rarely showed any traces of the soft tissues of fish but instead, consisted chiefly of the teeth, scales, and fins, with the bones being perfectly preserved in comparatively few instances. He therefore adopted a classification that divided fish into four groups (ganoids, placoids, cycloids, and ctenoids), based on the nature of the scales and other dermal appendages. That did much to improve fish taxonomy , but Agassiz's classification has since been superseded. With Louis de Coulon, both father and son, he founded

923-682: A past ice age . He presented the theory to the Helvetic Society that ancient glaciers flowed outward from the Alps, and even larger glaciers had covered the plains and mountains of Europe, Asia, and North America and smothered the entire Northern Hemisphere in a prolonged ice age. In the same year, he was elected a foreign member of the Royal Swedish Academy of Sciences . Before that proposal, Goethe , de Saussure , Ignaz Venetz, Jean de Charpentier, Karl Friedrich Schimper , and others had studied

994-703: A practical school of natural science that would be especially devoted to the study of marine zoology. The school collapsed soon after Agassiz's death but is considered to be a precursor of the nearby Woods Hole Marine Biological Laboratory . Agassiz had a profound influence on the American branches of his two fields and taught many future scientists who would go on to prominence, including Alpheus Hyatt , David Starr Jordan , Joel Asaph Allen , Joseph Le Conte , Ernest Ingersoll , William James , Charles Sanders Peirce , Nathaniel Shaler , Samuel Hubbard Scudder , Alpheus Packard , and his son Alexander Emanuel Agassiz . He had

1065-512: A profound impact on the paleontologist Charles Doolittle Walcott and the natural scientist Edward S. Morse . Agassiz had a reputation for being a demanding teacher. He would allegedly "lock a student up in a room full of turtle-shells, or lobster-shells, or oyster-shells, without a book or a word to help him, and not let him out till he had discovered all the truths which the objects contained." Two of Agassiz's most prominent students detailed their personal experiences under his tutelage: Scudder, in

1136-537: A promontorium on the moon are also named in his honor. Cape Agassiz , a headland situated in Palmer Land , Antarctica , is named in his honor. A main-belt asteroid , 2267 Agassiz , is also named in association with him. Several animal species are named in honor of him, including and the most well-known, In 2005, the European Geosciences Union Division on Cryospheric Sciences established

1207-442: A short magazine article for Every Saturday , and Shaler , in his Autobiography . Those and other recollections were collected and published by Lane Cooper in 1917, which Ezra Pound would draw on for his anecdote of Agassiz and the sunfish . In the early 1840s, Agassiz named two fossil fish species after Mary Anning ( Acrodus anningiae and Belenostomus anningiae ) and another after her friend, Elizabeth Philpot . Anning

1278-734: A two-year effort on the part of neighborhood residents, the Cambridge City Council voted unanimously to change the name to the Baldwin Neighborhood. An elementary school, the Agassiz Elementary School in Minneapolis, Minnesota , existed from 1922 to 1981. An ancient glacial lake that formed in central North America, Lake Agassiz , is named after him, as are Mount Agassiz in California's Palisades , Mount Agassiz in

1349-458: Is a boulder from a glacial moraine of the Aar near the site of the old Hôtel des Neuchâtelois , not far from the spot where his hut once stood. His grave is sheltered by pine trees from his old home in Switzerland. The Cambridge elementary school north of Harvard University was named in his honor, and the surrounding neighborhood became known as " Agassiz " as a result. The school's name was changed to

1420-505: Is better than a hypothesis that is difficult to test. Agassiz had a close association with his student and field assistant, the geologist Charles Hartt who eventually refuted Agassiz's theories about the Amazon based on his fieldwork there. Instead of evidence for any glacial processes, he found chemically weathered sediments from marine and tropical fluvial, not glacial, processes, a finding that later geologists confirmed. Agassiz hypothesis that

1491-399: Is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classification, including of extinct species such as megalodon , and to the study of historical geology , including

1562-538: Is middle Cenomanian. Although Lebanon is now a part of Asia, the depositional environment for both formations would have been located off the coast of northern Africa during the Cretaceous, which would technically make their biota African rather than Asian. The Cretaceous formations of Lebanon laterally vary from east to west; the western lowland "coastal" sequence (containing Sahel Aalma) is over 2000 metres thick and primarily consists of deep water limestone and chalk, while

1633-719: Is no longer used by the ICS . It overlaps the lower part of the Urgonian  [ pl ] stage, which is sometimes used in western European stratigraphy. In North America , the late Coahulian and the early Comanchean correspond to the Barremian. In New Zealand , it falls within the Mokoiwian , and in Japan it corresponds to the late Aritan . The Barremian is often subdivided into two substages or subages, Lower/Early and Upper/Late Barremian. In

1704-571: The Aar Glaciers and for a time made it his home to investigate the structure and movements of the ice. Agassiz visited England, and with William Buckland , the only English naturalist who shared his ideas, made a tour of the British Isles in search of glacial phenomena, and became satisfied that his theory of an ice age was correct. In 1840, Agassiz published a two-volume work, Études sur les glaciers ("Studies on Glaciers"). In it, he discussed

1775-939: The Magellan Strait , which drew the praise of Charles Darwin . Following the establishment of the first U.S. Society for the Prevention of Cruelty to Animals in New York City in 1866, Agassiz was called on to help settle disputes about animal behavior. He deemed the way turtles were shipped caused them suffering, while P.T. Barnum argued with Agassiz' support that his snakes would eat only live animals. His second wife, Elizabeth Cary Agassiz , assisted him in preparing his A Journey in Brazil . Along with her stepson, Alexander Agassiz , she wrote Seaside Studies in Natural History and Marine Animals of Massachusetts . Elizabeth wrote at

1846-553: The Societé des Sciences Naturelles , of which he was the first secretary and in conjunction with the Coulons also arranged a provisional museum of natural history in the orphan's home. Agassiz needed financial support to continue his work. The British Association and the Earl of Ellesmere , then Lord Francis Egerton , stepped in to help. The 1290 original drawings made for the work were purchased by

Spending his early life in Switzerland , he received

1988-925: The Uinta Mountains of Utah, Agassiz Peak in Arizona, Agassiz Rock in Massachusetts, and the Agassizhorn in the Bernese Alps in his native Switzerland. Agassiz Glacier in Montana, Agassiz Creek in Glacier National Park , Agassiz Glacier in the Saint Elias Mountains of Alaska, and Mount Agassiz in the White Mountains of New Hampshire also bear his name. A crater on Mars , Crater Agassiz , and

2059-481: The glaciers of the Alps, and Goethe, Charpentier, and Schimper had even concluded that the erratic blocks of alpine rocks scattered over the slopes and summits of the Jura Mountains had been moved there by glaciers. Those ideas attracted the attention of Agassiz, and he discussed them with Charpentier and Schimper, whom he accompanied on successive trips to the Alps. Agassiz even had a hut constructed upon one of

The Amazon rainforest was split into two large blocks by extensive savanna during the LGM. With the aid of a grant of money from the king of Prussia , Agassiz crossed the Atlantic in the autumn of 1846 to investigate the natural history and geology of North America and to deliver

2201-459: The Animal Kingdom , Ichthyology, and Comparative Embryology" as a part of the Lowell Lecture series. These lectures were widely attended with up to 5,000 people in attendance on some nights. It was during these lectures that Agassiz announced for the first time that black and white people had different origins but were part of the same species. Agassiz repeated this lecture 10 months later to

The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone , which is biologically near the first appearance of the ammonite Paradeshayesites oglanlensis . The Barremian falls in the Gallic epoch , a subdivision of the Cretaceous that

2343-547: The Charleston Literary Club but changed his original stance, claiming that black people were physiologically and anatomically a distinct species. Agassiz believed that humans did not descend from one single common ancestor. He believed that like plants and animals, various regions have differentiated species of humans . He considered this hypothesis testable, and matched to the available evidence. He also indicated that there were obvious geographical barriers that were

2414-621: The Earl and presented by him to the Geological Society of London . In 1836, the Wollaston Medal was awarded to Agassiz by the council of that society for his work on fossil ichthyology. In 1838, he was elected a foreign member of the Royal Society . Meanwhile, invertebrate animals engaged his attention. In 1837, he issued the "Prodrome" of a monograph on the recent and fossil Echinodermata ,

2485-556: The Harvard botanist Asa Gray despite their disagreements. Agassiz believed each human race had been separately created, but Gray, a supporter of Charles Darwin , believed in the shared evolutionary ancestry of all humans. In addition, Agassiz was a member of the Scientific Lazzaroni , a group of mostly physical scientists who wanted American academia to mimic the more autocratic academic structures of European universities, but Gray

In 1850, he had married Elizabeth Cabot Cary, who later wrote introductory books about natural history and a lengthy biography of her husband after he had died. Agassiz served as a nonresident lecturer at Cornell University while he was also on faculty at Harvard. In 1852, he accepted a medical professorship of comparative anatomy at Charlestown, Massachusetts , but he resigned in two years. From then on, Agassiz's scientific studies dropped off, but he became one of

Agassiz took part in a monthly gathering called the Saturday Club at the Parker House , a meeting of Boston writers and intellectuals. He was therefore mentioned in a stanza of the Oliver Wendell Holmes Sr. poem " At

Baldwin School on May 21, 2002, because of concerns about Agassiz's involvement in scientific racism and to honor Maria Louise Baldwin , the African-American principal of the school, who served from 1889 to 1922. The neighborhood, however, continued to be known as Agassiz. c.  2009 , neighborhood residents decided to rename the neighborhood's community council as the "Agassiz-Baldwin Community". Then, in July 2021, culminating

In the early stages of his career in Neuchatel, Agassiz also made a name for himself as a man who could run a scientific department well. Under his care, the University of Neuchâtel soon became a leading institution for scientific inquiry. In 1842 to 1846, Agassiz issued his Nomenclator Zoologicus , a classification list with references of all names used in zoological genera and groups. He

In 1829, he received the degree of doctor of philosophy at Erlangen and, in 1830, that of doctor of medicine at Munich. Moving to Paris, he came under the tutelage of Alexander von Humboldt and later received his financial benevolence. Humboldt and Georges Cuvier launched him on his careers of respectively geology and zoology. Ichthyology soon became

3053-520: The best-known scientists in the world. By 1857, Agassiz was so well-loved that his friend Henry Wadsworth Longfellow wrote "The Fiftieth Birthday of Agassiz" in his honor and read it at a dinner given for Agassiz by the Saturday Club in Cambridge . Agassiz's own writing continued with four (of a planned 10) volumes of Natural History of the United States , published from 1857 to 1862. He also published

3124-492: The deck." From his first marriage to Cecilie Braun, Agassiz had two daughters, Ida and Pauline , and a son, Alexander . In 1863, Agassiz's daughter Ida married Henry Lee Higginson , who later founded the Boston Symphony Orchestra and was a benefactor to Harvard and other schools. On November 30, 1860, Agassiz's daughter Pauline was married to Quincy Adams Shaw (1825–1908), a wealthy Boston merchant and later

3195-489: The earliest representatives of modern fish groups such as acanthomorphs , African butterflyfish and eels . The Sannine Formation and its fossil fishes have been known of since Roman Phoenicia . The earliest mention of them is in the Chronicon by Eusebius around 314 CE (references to earlier mentions by Herodotus are thought to be apocryphal), who mentions fossil fishes commonly being found during quarrying operations in

3266-477: The early 19th century, contributing to the study of these specimens by scientists such as Louis Agassiz . The Hadjoula site was only discovered in the late 19th century, and the Nammoura site in the early 20th century.

3337-495: The eastern "mountain" sequence (containing the Sannine Formation) is 500–700 metres thick and consists of shallow water limestone. Two different shallow-water environments are preserved by the formation: Nammoura preserves a nearshore inner continental shelf environment with significant terrestrial input, while Haqel & Hjoula preserve an outer continental shelf environment. The neritic nature of these habitats contrasts with

3408-864: The effect of the last ice age in North America. In August 1857, Agassiz was offered the chair of palaeontology in the Museum of Natural History, Paris , which he refused. He was later decorated with the Cross of the Legion of Honor . Agassiz continued his lectures for the Lowell Institute. In succeeding years, he gave lectures on "Ichthyology" (1847–1848), "Comparative Embryology" (1848–1849), "Functions of Life in Lower Animals" (1850–1851), "Natural History" (1853–1854), "Methods of Study in Natural History" (1861–1862), "Glaciers and

Agassiz left the images to Harvard, and they remained in the Peabody Museum's attic until 1976, when they were rediscovered by Ellie Reichlin, a former staff member. The 15 daguerrotypes were in a case with the embossing "J. T. Zealy, Photographer, Columbia," with several handwritten labels, which helped in later identification. Reichlin spent months doing research to try to identify

After his return in August 1866, an account of the expedition, A Journey in Brazil , was published in 1868. In December 1871, he made a second eight-month excursion, known as the Hassler expedition under the command of Commander Philip Carrigan Johnson (the brother of Eastman Johnson ) and visited South America on its southern Atlantic and Pacific Seaboards. The ship explored

Louis Agassiz was born in the village of Môtier ( fr ) (now part of Haut-Vully which merged into Mont-Vully in 2016) in the Swiss Canton of Fribourg . He was the son of a pastor, Louis Rudolphe and his wife, Rose Mayor. His father was

The publication of the work gave fresh impetus to the study of glacial phenomena in all parts of the world. Familiar then with recent glaciation, Agassiz and the English geologist William Buckland visited the mountains of Scotland in 1840. There, they found clear evidence in different locations of glacial action. The discovery

3834-406: The history of those fish, and Martius selected Agassiz for this project. Agassiz threw himself into the work with an enthusiasm that would go on to characterize the rest of his life's work. The task of describing the Brazilian fish was completed and published in 1829. It was followed by research into the history of fish found in Lake Neuchâtel . Enlarging his plans, he in 1830 issued a prospectus of

3905-416: The mountains, and cites them as evidence of the Biblical Flood . The site that these fish were recovered from is thought to correspond to the modern Haqel site. Around 1250, fossil fishes were presented to Louis IX during the Seventh Crusade and documented by Jean de Joinville , although it remains uncertain whether these originated from Haqel or the younger Sahel Alma site. The first European to visit

3976-473: The movements of the glaciers, their moraines , and their influence in grooving and rounding the rocks and in producing the striations and roches moutonnées seen in Alpine-style landscapes. He accepted Charpentier and Schimper's idea that some of the alpine glaciers had extended across the wide plains and valleys of the Aar and Rhône , but he went further by concluding that in the recent past, Switzerland had been covered with one vast sheet of ice originating in

4047-424: The northeast of Scotland. The strange forms of Pterichthys , Coccosteus , and other genera were then made known to geologists for the first time. They were of intense interest to Agassiz and formed the subject of a monograph by him published in 1844–1(45: Monographie des poissons fossiles du Vieux Grès Rouge, ou Système Dévonien (Old Red Sandstone) des Îles Britanniques et de Russie ( Monograph on Fossil Fish of

Pterosaur fossils have been recovered from the formation, including those of Mimodactylus and Microtuban . The pythonomorphs Pontosaurus , Eupodophis and probably Aphanizocnemus are known from the formation. Insects are also known from compression fossils, including those of

4189-530: The overall average down. Oppositely, he included Peruvian skull measurements alongside Native American calculations even though the Peruvian numbers lowered the average score. Despite Morton's unsound methods, his published work on cranial capacities across races was deemed authoritative in the United States and Europe. Morton is a primary influence on Agassiz's belief in polygenism. John Amory Lowell invited Agassiz to present twelve lectures in December 1846 on three subjects titled " The Plan of Creation as shown in

4260-429: The people in the photos, but Harvard University did not make efforts to contact the families and licensed the photos for use. In 2011, Tamara Lanier wrote a letter to the president of Harvard that identified herself as a direct descendant of the Taylors and asked the university to turn over the photos to her. In 2019, Taylor's descendants sued Harvard for the return of the images and unspecified damages. The lawsuit

4331-494: The principal museums in Europe. Meeting Cuvier in Paris, he received much encouragement and assistance from him. In 1833, he married Cecile Braun, the sister of his friend Alexander Braun and established his household at Neuchâtel . Trained to scientific drawing by her brothers, his wife was of the greatest assistance to Agassiz, with some of the most beautiful plates in fossil and freshwater fishes being drawn by her. Agassiz found that his palaeontological analyses required

4402-577: The rock of the surrounding region, the slates of Glarus and the limestones of Monte Bolca , soon attracted his attention. At the time, very little had been accomplished in their scientific study. Agassiz as early as 1829, planned the publication of a work. More than any other, it would lay the foundation of his worldwide fame. Five volumes of his Recherches sur les poissons fossiles ( Research on Fossil Fish ) were published from 1833 to 1843. They were magnificently illustrated, chiefly by Joseph Dinkel . In gathering materials for that work, Agassiz visited

4473-820: The time who became well known by analyzing fossils brought back by Lewis and Clark. One of Morton’s personal projects involved studying cranial capacity of human skulls from around the world. Morton aimed to use craniometry to prove that white people were biologically superior to other races. His work " Crania Aegyptiaca" claimed to support the polygenism belief that the races were created separately and each had their own unique attributes. Morton relied on other scientists to send him skulls along with information about where they were acquired. Factors that can affect cranial capacity, such as body size and gender, were not taken into consideration by Morton. He made questionable judgment calls such as dismissing Hindu skull calculations from his Caucasian cranial measurements because they brought

4544-437: Was a paleontologist known around the world for important finds, but because of her gender, she was often not formally recognized for her work. Agassiz was grateful for the help that the women gave him in examining fossil fish specimens during his visit to Lyme Regis in 1834. Agassiz died in Cambridge, Massachusetts , in 1873 and was buried on the Bellwort Path at Mount Auburn Cemetery , joined later by his wife. His monument

4615-444: Was a staunch opponent of that group. Agassiz's engagement for the Lowell Institute lectures precipitated the establishment in 1847 of the Lawrence Scientific School at Harvard University, with Agassiz as its head. Harvard appointed him professor of zoology and geology, and he founded the Museum of Comparative Zoology there in 1859 and served as its first director until his death in 1873. During his tenure at Harvard, Agassiz studied

4686-432: Was a well-known natural scientist of his generation in America. In addition to being a natural scientist, Agassiz wrote prolifically in the field of scientific polygenism after he came to the United States. Upon arriving in Boston in 1846, Agassiz spent a few months acquainting himself with the northeast region of the United States. He spent much of his time with Samuel George Morton , a famous American anthropologist at

4757-408: Was announced to the Geological Society of London in successive communications. The mountainous districts of England, Wales , and Ireland were understood to have been centres for the dispersion of glacial debris. Agassiz remarked "that great sheets of ice, resembling those now existing in Greenland , once covered all the countries in which unstratified gravel (boulder drift) is found; that this gravel

4828-422: Was elected as a member of the American Philosophical Society in 1843. The vacation of 1836 was spent by Agassiz and his wife in the little village of Bex , where he met Jean de Charpentier and Ignaz Venetz . Their recently announced glacial theories had startled the scientific world, and Agassiz returned to Neuchâtel as an enthusiastic convert. In 1837, Agassiz proposed that the Earth had been subjected to

4899-436: Was in general produced by the trituration of the sheets of ice upon the subjacent surface, etc." In his later years, Agassiz applied his glacial theories to the geology of the Brazilian tropics, including the Amazon.
