Lycaenops ornatus is a carnivorous therapsid that lived during the Permian era. They are mammal like reptiles and were there way before the dinosaurs stole all the fame. Therapsids are the far ancestors of mammals (you and me) and they are awesome.
The skeleton above is shamelesly stolen from this picture of the specimen of the New York Museum. The critter down there is my attempt at reconstructing it (badly).
