Pareiasauria

Scutosaurus ("shield lizard") is an extinct genus of pareiasaurian reptile. Fossils have been found in the Sokolki Assemblage Zone of the Malokinelskaya Formation in European Russia, close to the Ural Mountains, dating to the late Permian (Lopingian) between 259 and 252 million years ago. Its genus name refers to large plates of armor scattered across its body. With a body mass suggested to exceed , it was one of the largest reptiles of the Permian period.

Pareiasaurus (from , "cheek" and , "lizard") is an extinct genus of pareiasauromorph reptile from the Permian period. It was a typical member of its family, the pareiasaurids, which take their name from this genus.

Bradysaurus is a genus of large, primitive and widespread pareiasaur. They possessed a covering of armoured scutes, likely serving as defense against their main predators, the gorgonopsians.

Elginia is an extinct genus of pareiasaurid known from the Late Permian of Scotland and China. It was named for the area around Elgin in Scotland, which has yielded many fossils referred to as the Elgin Reptiles.

Bunostegos ("knobbly [skull] roof") is an extinct genus of pareiasaur parareptile from the Late Permian of the Agadez Region in Niger. The type species, Bunostegos akokanensis, was named from the Moradi Formation in 2003. It was a cow-sized animal with a distinctive skull that had large bony knobs, similar in form to those of other pareiasaurs but far larger. The species appears to have lived in a desert in the centre of the supercontinent of Pangaea.

Shihtienfenia is an extinct genus of pareiasaurid parareptile from the Late Permian of China.

Pareiasaurs (meaning "cheek lizards") are an extinct clade of large, herbivorous reptiles (traditionally considered "parareptiles") that existed during the Permian period. Members of the group were armoured with osteoderms which covered large areas of the body. They first appeared in southern Pangea during the Middle Permian, before becoming globally distributed during the Late Permian. Pareiasaurs were the largest reptiles of the Permian, some reaching sizes over , equivalent to the largest contemporary therapsids. Pareiasaurs became extinct in the end-Permian mass extinction event.

Deltavjatia is an extinct species of pareiasauromorph procolophonoid from the Tatarian stage of the Permian time period. It had a large body of about in length. Deltavjatia was an herbivore and lived in what is now Russia. The first specimen of Deltavjatia was a specimen of a skull and lower mandible (PIN 2212/1), found in the Urpalov Formation in Kotelnich, Vyatka River. Since then, numerous mostly complete skeletons have been found, many of them being so well preserved due to the silty, anaerobic environment of the Kotelnich deposits that fossilised white blood cells are able to be distingui

Arganaceras ("Argana horn") is a medium-sized pareiasaur from the Late Permian Ikakern Formation of Morocco. It was about in length and had a horn-like structure on its snout.

Nanoparia is an extinct genus of pareiasaur known from the Permian of South Africa.
