Peirosaurus is an extinct genus of peirosaurid crocodylomorph known from the Late Cretaceous period (late Maastrichtian stage) of Minas Gerais, southern Brazil. It contains a single species, Peirosaurus torminni. It is the type genus of the family Peirosauridae.
==Discovery== Peirosaurus is known from the holotype DGM 433-R, fragmentary skull (left premaxilla bearing five teeth, isolated maxillary and dentary teeth and left palpebral bone) and partial postcranial skeleton including radius, ulna, left pubis and ischium, some presacral and a single caudal vertebrae, ribs, haemal arches and dermal plates. It was collected by Llewellyn Ivor Price in 1947-1949 at the Price Quarry 3, Peirópolis Site near Uberaba, in the Serra da Galga Formation (Bauru Group), dating to the late Maastrichtian stage of the Late Cretaceous, about 68-66 million years ago.
