Abstract
Two new crocodyliform specimens found in a recently discovered locality from the Late Cretaceous of Patagonia (Argentina) are described herein. One of them comprises an almost complete skull found in articulation with the lower jaws, while the other consists of the anterior region of the lower jaws and fragmentary remains of the palate. These two specimens differ in the morphology of their lower jaws (e.g., height of mandibular symphysis, pattern of ornamentation on ventral surface of mandibular ramus, concavity of medial surface of splenials, shape of splenial-dentary suture on ventral surface of mandibular symphysis) and probably belong to different taxa. The more complete specimen is considered to be a new taxon, Araripesuchus buitreraensis, diagnosed by the combination of the following characters (autapomorphic characters are indicated with an asterisk): long and acute anterior process of frontals extending anteriorly between the nasals; frontals extending into supratemporal fenestra; narrow ...Keywords
