OTHNIEL See also:CHARLES See also:MARSH (1831-1899)  , See also:American palaeontologist, was See also:born in See also:Lockport, New See also:York, on the 29th of See also:October 1831 . He graduated at Yale See also:College in 186o, and studied See also:geology and See also:mineralogy in the See also:Sheffield scientific school, New Haven, and afterwards palaeontology and See also:anatomy in See also:Berlin, See also:Heidelberg and See also:Breslau . Returning to See also:America in 1866 he was appointed See also:professor of vertebrate palaeontology at Yale College, and there began the researches of the fossil See also:vertebrata of the western states, whereby he established his reputation . He was aided by a private See also:fortune from his See also:uncle, See also:George See also:Peabody, whom he induced to establish the Peabody Museum of Natural See also:History (especially devoted to See also:zoology, geology and mineralogy) in the college . In May 1871 he discovered the first pterodactyl remains found in America, and in subsequent years he brought to See also:light from See also:Wyoming and other regions many new genera and families, and some entirely new orders of See also:extinct vertebrata, which he described in monographs or periodical articles . These included remains of the Cretaceous toothed birds Hesperornis and Ichthyornis, the Cretaceous flying-See also:reptiles (Pteranodon), the See also:swimming reptiles or Mosasauria, and the Cretaceous and See also:Jurassic See also:land reptiles (Dinosauria) among which were the Brontosaurus and Atlantosaurus . The remarkable mammals which he termed Brontotheria (now grouped as See also:Titanotheriidae), and the huge Dinocerata, one being the Uintatherium, were also brought to light by him . Among his later discoveries were remains of See also:early ancestors of horses in America . On becoming See also:vice-See also:president of the American Association for the See also:Advancement of See also:Science in 1875 he gave an address on the " Introduction and See also:Succession of Vertebrate See also:Life in America," summarizing his conclusions to that date . He repeatedly organized and often accompanied scientific exploring expeditions in the Rocky Mountains, and their results tended in an important degree to support the doctrines of natural selection and See also:evolution . He published many papers on these, and found See also:time—besides that necessarily given to the See also:accumulation and care of the most extensive collection of fossils in the See also:world—to write See also:Odontornithes: A Monograph on the Extinct Toothed Birds of See also:North America (188o) ; Dinocerata: A Monograph on an Extinct See also:Order of Gigantic Mammals (1884) ; and The Dinosaurs of North America (1896) . His See also:work is full of accurately recorded facts of permanent value .

He was See also:

long in See also:charge of the See also:division of vertebrate palaeontology in the See also:United States See also:Geological Survey, and received many scientific honours, medals and degrees, American and See also:foreign . He died in New Haven on the 18th of See also:March 1899 . Mag . (1899), p . 237 .
