Abstract

New specimens of Ceratosuchus from the transitional Paleocene-Eocene (Clarkforkian) sediments of the Bighorn Basin, Wyoming, indicate that this genus is closely allied to the primitive alligator Allognathosuchus. Ceratosuchus is thus far known only from Clarkforkian horizons, where it is much rarer than Allognathosuchus, suggesting some ecological specialization. Ceratosuchus and Allognathosuchus are both interpreted as generalized omnivorous predators.
