Rauisuchus was a 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.
