Titanotylopus
''Titanotylopus'' is an extinct genus of terrestrial herbivore the family Camelidae, endemic to North America from the Miocene through Pleistocene 10.3 mya—300,000 years ago, existing for approximately .〔(PaleoBiology Database: ''Titanotylopus'', basic info )〕
Its name is derived from the Greek words Τιτάν, τύλος and πούς — "Titan", "knob" and "foot"; thus, "giant knobby-foot."
==Paleobiology==
''Titanotylopus'' is distinguished from other early large camelids by its large upper canines and other distinguishing dental characteristics, and absence of lacrimal vacuities in the skull. Unlike the smaller, contemporaneous ''Camelops'', ''Titanotylopus'' had relatively broad second phalanges, suggesting that it had true padded "cameltoes," like modern camels.〔Björn Kurtén and Elaine Anderson ''Pleistoceone Mammals of North America'' (New York : Columbia University Press, 1980), pp. 301–302 ISBN 0-231-03733-3〕
The species ''Titanotylopus spatulus'' was characterized by broad, spatula-like incisors. It has been found at Grand View, Red Light, Hudspeth County, Texas, Donnelly Ranch, White Rock, Kansas, Mullen II (Kansas), Sandahl Local Fauna (Nebraska) and Vallecito Creek, Colorado, 111 Ranch, Arizona in North America.
