''Biarmosuchus'' is an extinct genus of biarmosuchian therapsid that lived around 267 mya during the Middle Permian period.''Biarmosuchus'' was discovered in the Perm region of Russia. The first specimen was found in channel sandstone that was deposited by flood waters originating from the young Ural mountains. ==Description== ''Biarmosuchus'' was a medium-sized predator, similar in size to a large dog, grew up to 1.5–2 m in length with a skull length 15 cm (immature) to 21 cm.It was a lightly built, probably agile animal that would have fed on smaller tetrapods. Their legs are quite long, and the animals were probably quite agile in spite of their size. A large opening for the eye and a small temple opening common in primitive mammal-like reptiles, this lends to a weak bite but how it ate is pure speculation. The teeth contained eight small incisors on the palate, followed by a canine tooth and a further five canine teeth. So together the species contained fourteen upper teeth and twelve lower teeth of small size (Kemp 1982).
