Edward Drinker Cope

Edward Drinker Cope (1840–1897) was an American paleontologist and comparative anatomist, as well as a noted herpetologist and ichthyologist. He was a rival of paleontologist Othniel Marsh. In 1891, Marsh's employee John Hatcher discovered Torosaurus, a species larger than Cope's most important find, Monoclonius.
