Phthinosuchus discors |

Phthinosuchus was a therapsid (mammal-like reptile) that lived in the Late Permian of Russia. Phthinosuchus is the sole member of its family and suborder, although Phthinosaurus may be a relative. Phthinosuchus is one of the most primitive therapsids, and its ancestors must have branched off early from the main therapsid line.
Phthinosuchus was 1.5 m long with a 20 cm skull, and looked much like the Sphenacodontids, such as Dimetrodon and Sphenacodon. Its temporal fenestrae were larger than those of the Sphenacodontids.[1][2] Like the other early therapsids, it was probably scaly skinned, sprawling, and carnivorous.
