Unlike saurischians, ornithischians had no teeth in the front of their mouth and they had bonelike tendons in the back region. The common ancestor of these dinosaurs was much like archosaurs. Archosaurs were small, long-legged carnivores that walked and ran on their hind limbs meaning that they were bipedal.
