Abstract
Two theropod dinosaur pelvic regions from the Dinosaur Canyon Member of the Moenave Formation in northeastern Arizona are assigned to Syntarsus sp. Te trapod fossils from the Moenave Formation, especially the crocodylomorph Pr otosuchus and the ichnotaxon Eubrontes, indicate it is entirely of Early Ju rassic (Hettangian) age. The Moenave Formation thus contains one of a handf ul of Hettangian-age tetrapod assemblages known worldwide.
