This fossil, which was found in 2004, near the town of Monte Alto, in São Paulo state is very well preserved and quite complete. Most importantly, skull material has been found and this can help to link this fossil specimen with today's modern crocodiles. It would have grown to about 2 metres in length and would have been an active predator of smaller animals including dinosaurs. Biomechanical analyses indicate its oreinirostral (dome-shaped) skull was quite efficient, producing relatively high bite forces (between 828–1013 Newtons), with a strong, controlled bite for its body size. [3] Perhaps it was more terrestrial than its modern relatives, using its semi-upright gait to pursue prey.[4]
