Kayentatherium

Kayentatherium is an extinct genus of tritylodontid cynodonts that lived during the Early Jurassic. It is one of two tritylodonts from the Kayenta Formation of northern Arizona, United States.

Kayentatherium means "Kayenta Beast", and is named for the geological formation in which it was found, the Kayenta Formation. Kayentatherium is known from several specimens. The specific name honors paleontologist Samuel Welles, who worked with the University of California Museum of Paleontology in much of the pioneering work on the paleontology of the Kayenta Formation.
