| Abstract: | A new Late Cretaceous Mesoeucrocodylian from the Adamantina Formation (Bauru Basin), São Paulo State, Brazil is described. The main features of this new species are the short, high oreinirostral rostrum, the large laterally positioned orbital notches and external nares in the anteriormost portion of the rostrum. The mandible is robust and concave-shaped in relation to the skull. The dentition is highly specialized, with two prominent incisiform teeth, a hypertrophied caniniform, and seven molariform teeth. The molariform teeth are ornamented with denticles in their lingual surface and are smooth on their labial surface. The molariforms are elliptical in cross-section, presenting the largest axis in the labial-lingual direction. Such dental characteristics are unique among the terrestrial crocodylomorphs of the Gondwana. |
