Acaenasuchus (from the Greek akaina, meaning "thorn" and suchus, meaning "crocodile")[2] is an extinct genus of pseudosuchian, endemic to what would be presently be known as Arizona during the Late Triassic, specifically during the Carnian and Norian stages of the Triassic.[3] Acaenasuchus had a stratigraphic range of approximately 11.5 million years.[4] Acaenasuchus is further categorized as one of the type fauna that belong to the Adamanian LVF, based on the fauna of the Blue Mesa Member of the Chinle Petrified Forest Formation of Arizona, where Acaenasuchus was initially discovered.[3]
