Euchambersia

''Euchambersia'' was a therocephalian therapsid that lived during the Late Permian epoch, approximately 250 million years ago, in what is now South Africa.
==Description==

''Euchambersia'' was a unique therocephalian. It apparently had venom glands connected to its canine teeth. Like snakes, the teeth of ''Euchambersia'' were adapted to inject venom to kill its prey. A recess behind each canine tooth housed the venom gland, while grooves down the outer sides of the canine teeth delivered the venom into the puncture wound,〔(http://kfolinsb.public.iastate.edu/folinsbee_journal_of_verteb.pdf )〕 together with powerful jaws this made it a very efficient predator to hunt the herbivorous dicynodonts and pareiasaurs it encountered. The discovery of another therocephalian, Ichibengops, from Zambia, Africa, may indicate that venom was more common in therocephalians than previously believed, as the specimen had grooves above its teeth not unlike those of Euchambersia.〔http://www.sciencedaily.com/releases/2015/08/150813162339.htm〕
