''Phthinosuchus'' is an extinct genus of therapsid from the Middle Permian of Russia. ''Phthinosuchus'' is the sole member of the family Phthinosuchidae. ''Phthinosuchus'' may have been one of the most primitive therapsids, meaning that its ancestors may 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. Like the other early therapsids, it was probably sprawling and carnivorous. ==See also==
