Barinasuchus arveloi

Barinasuchus was the largest, and longest lived genus of Sebecid; with remains ranging from Mid Eocene rocks of Argentina and Mid Miocene rocks of Peru and Venezuela. The largest known terrestrial predator of the Cenozoic era; Barinasuchus stalked the savannahs and forests of South America preying on the large Notoungulates, rodents, and other prey animals of the continent. Like other Sebecids, the skull of Barinasuchus was laterally compressed, with jaws filled with flat, knife-like serrated teeth. These features make Sebecids morphologically similar in shape to the large non-avian dinosaurs of the Mesozoic.
