Rauisuchus

Rauisuchus was a basal archosaur which lived in what is now Brazil during the middle Triassic period (240-230 million years ago). Named after fossil collector Dr. Wilhelm Rau, Rauisuchus belonged to a group of land-dwelling relatives to crocodiles. These reptiles were among the top predators of their day, eating other reptiles for food and maybe hunting early dinosaurs.

Rauisuchus grew to a length of 13 feet (4m) and was 3 feet (90 cm) high at the hips. It had a weight of around 550 lbs (250 kg).
