The Kayenta Formation is a geological formation in the Glen Canyon Group that is spread across the Colorado Plateau province of the United States, including northern Arizona, northwest Colorado, Nevada, and Utah. Traditionally has been suggested as Sinemurian -Pliensbachian, but more recent dating of detrital zircons has yielded a depositional ...
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. [ 1 ] [ 2 ] 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 mesa is located on the Colorado Plateau near Kayenta, Arizona, and rises to over 8,168 ft (2,490 m). Its highest peak is located on Black Mesa's northern rim, a few miles south of the town of Kayenta. Reliable springs surfacing at several locations mean the mesa is more suitable for continuous habitation than much of the surrounding desert ...
S. kayentakatae was a relatively small dinosaur, reaching 2.5 m (8.2 ft) in length and 30 kg (66 lb) in body mass. [ 12] It had two small, parallel crests which may demonstrate an evolutionary step toward later and larger neotheropods, such as the more advanced and larger Dilophosaurus. Both possess a "weak joint" between the premaxillary and ...
