Biarmosuchus tener
Biarmosuchus tenerBiarmosuchus was a slender, long-limbed therapsid that prowled river systems across what is now European Russia during the Middle Permian. Large orbits indicate keen eyesight suited for dim conditions, while sharply differentiated canine teeth allowed it to puncture and subdue struggling prey. Its relatively upright posture provided superior mobility compared to earlier sprawling carnivores, marking an important transitional stage toward mammalian agility.
