Abstract

Dinnebitodon amarali, a new genus and species of Tritylodontidae, is described from the Early Jurassic Kayenta Formation of northeastern Arizona. It is distinguished from Kayentatherium wellesi by the possession of three (rather than one) upper incisors and upper postcanine teeth with two (rather than three) lingual cusps.
