Saurosuchus

Saurosuchus was a 20-foot pseudosuchian (a distant ancestor of crocodiles) which lived in Argentina during the middle Triassic Period about 230 million years ago. It was the largest carnivorous animal in its environment in terms of both length and weight, and it was likely the top predator within the Ischigualasto Formation, but that was before the dinosaurs arrived. Saurosuchus lived side-by-side with the meat-eating dinosaurs, but eventually carnivorous dinosaurs like Herrerasaurus, which were faster, more agile, and possibly more intelligent, drove these creatures to extinction.
