Skull of Thylacoleo carnifex. Like other thylacoleonids, Thylacoleo had blade-like third premolar teeth in the upper and lower jaws, that functioned as the carnassial teeth, with these teeth being present much further forwards in the jaw than in other mammals. [19] [20] Compared to earlier thyacoleonids, the third premolars were considerably ...
