奧塞內爾·查利斯·馬什

馬什出生於紐約州洛克波特（Lockport）。1860年從耶魯學院畢業，並且前往雪菲爾科學學校（Sheffield Scientific School）研讀地質學與礦物學。之後又到到柏林、海德堡與弗羅茨瓦夫研究古生物學與解剖學。

1866年，馬什回到美國，並且成為耶魯大學的脊椎動物古生物學家。並說服他的叔叔喬治·皮巴第（George Peabody）在耶魯大學建立關於自然史的皮巴第博物館（Peabody Museum）。

1871年5月，馬什發現了第一具美洲翼龍的化石。同時他也發現了早期馬類的遺骸。馬什描述了一些白堊紀有齒鳥類（例如“魚鳥”Ichthyornis與“黃昏鳥”Hesperornis）、飛行爬蟲類，以及侏儸紀恐龍（例如異特龍與迷惑龍）。

19世紀末，馬什與當時的另一位古生物學家愛德華·德克林·科普（Edward Drinker Cope）展開了一場激烈的化石發現競賽，又稱為“化石戰爭”（Bone Wars），他們倆人在這段期間發現了超過120個恐龍物種。而他自己就發現了80種物種

馬什於1899年逝世，安葬於紐哈芬的園林街墓園（Grove Street Cemetery）

Marsh's finds formed the original core of the collection of Yale's Peabody Museum of Natural History. The museum's Great Hall is dominated by the first fossil skeleton of Brontosaurus that he discovered, which was reclassified as Apatosaurus for a time. However, an extensive study published in 2015 concluded that Brontosaurus was a valid genus of sauropod distinct from Apatosaurus.「6」

He donated his home in New Haven, Connecticut, to Yale University in 1899. The Othniel C. Marsh House, now known as Marsh Hall, is designated a National Historic Landmark. The grounds are now known as the Marsh Botanical Garden.

Marsh named the f ollowing dinosaur genera: Allosaurus(1877), Ammosaurus(1890), Anchisaurus(1885), Apatosaurus(1877), Atlantosaurus(1877), Barosaurus(1890), Brontosaurus(1879), Camptosaurus(1885), Ceratops(1888), Ceratosaurus(1884), Claosaurus(1890), Coelurus(1879), Creosaurus(1878), Diplodocus(1878), Diracodon(1881), Dryosaurus(1894), Dryptosaurus(1877), Labrosaurus(1896), Laosaurus(1878), Nanosaurus(1877), Nodosaurus(1889), Ornithomimus(1890), Pleurocoelus(1891), Priconodon(1888), Stegosaurus(1877), Torosaurus(1891), Triceratops(1889). He named the subordersCeratopsia(1890),Ceratosauria(1884),Ornithopoda(1881),Stegosauria(1877), andTheropoda. He also named the familiesAllosauridae(1878),Anchisauridae(1885),Camptosauridae(1885),Ceratopsidae(1890),Ceratosauridae,Coeluridae,Diplodocidae(1884),Dryptosauridae(1890),Nodosauridae(1890),Ornithomimidae(1890),Plateosauridae(1895), andStegosauridae(1880). He also named many individual species of dinosaurs. The dinosaur Othnieliawas named in 1977 by P. Galton as a tribute to Marsh, as was Marshosaurus bicentesmus(Madsen, 1976).
