Dinodontosaurus (meaning "terrible-toothed lizard") is a genus of dicynodont therapsid. It was one of the largest herbivores of the Triassic (about 8 feet (2.4 m) long and weighing a few hundred pounds) and had a beak corneum. It lived in the Middle Triassic but disappeared in the Upper Triassic.

Species

• Dinodontosaurus turpior^[1] is the most common species of dicynodont that existed in the Middle Triassic, and more common in the fossil layers that age in Rio Grande do Sul, in geopark of paleorrota. They are found mainly in the Paleontological Site Chiniquá in São Pedro do Sul and Candelária, where a group of ten pups^[2] were found together, demonstrating that these animals had strategies for coexistence in a group and caring for their offspring.

• Dinodontosaurus pedroanum ^[3] was a species of dicynodonts herbivore that lived in the region of paleorrota, Brazil (8 fossils collected) and Argentina (2 fossils collected). It was described the first time by Tupi Caldas in 1936 and is synonymous Dinodontosaurus oliveirai, Romer 1943.
