Temporal range: Middle Triassic, 240–230 Ma
Rauisuchus tiradentes'' is an extinct basal archosaur which lived in what is now the Geopark of Paleorrota, 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 4 m and was 90 cm high at the hips. It had a weight of around 250 kg.
