Lycaenos biting. Lycaenops, a genus of carnivorous therapsid, lived during the Permian, about 270.6-251 mya, in what is now South Africa. Lycaenops had a long and slender skull, with a set of dog-like fangs set into both its upper and lower jaws.[2] These pointed canine teeth were ideal for the use of stabbing and/or tearing at the flesh of any large prey that it came upon. Lycaenops most likely hunted small vertebrates such as reptiles and dicynodonts.
