Protorosaurus

Protorosaurus ("first lizard") is a genus of lizard-like early archosauromorph reptiles. Members of the genus lived during the late Permian period in Germany and Brazil. Once believed to have been an ancestor to lizards, "Protorosaurus" is now known to be one of the oldest members of the lineage that would eventually lead to archosaurs such as crocodilians and dinosaurs.
Description.
"Protorosaurus" grew up to in length, and was a slender, lizard-like animal, with long legs and a long neck. Its body form suggests that it was fast-moving, although it may have fed primarily on insects. "Protorosaurus" was closely related to "Czatkowiella" from the Early Triassic of Poland.
Discovery.
In 1914, a new ceratopsian dinosaur found by Lawrence Lambe was again given the name "Protorosaurus" (in this sense meaning "before "Torosaurus""). When Lambe found that the name had already been used for the early archosauromorph, he renamed his ceratopsian "Chasmosaurus".
In Geopark of Paleorrota, Rio Grande do Sul, Brazil, 3 vertebrae and some bones of the animal were found.
