Pintosaurus

Pintosaurus is an extinct genus of basal procolophonid[1] parareptile from Late Permian or Early Triassic (Changhsingian stage, or early Triassic) deposits of northeastern Uruguay. It is known from the holotype FC-DPV 1181, a partial skull. It was collected from the Buena Vista Formation of the Paraná Basin, in Colonia Orozco, Cerro Largo Department. It was first named by Graciela Piñeiro, Alejandra Rojas and Martín Ubilla in 2004 and the type species is Pintosaurus magnidentis. The specific name means "large dentary" in Greek.[2]
