Staurikosaurus is one of the earliest known dinosaurs. It was a small but active bipedal predator, that preyed on small and medium-sized terrestrial vertebrates such as cynodonts, rhynchosaurs, and herbivorous synapsids. This man size animal probably hunted smaller animals as well as young animals and possibly eggs. The mandible of Staurikosaurus suggests that a sliding joint in the jaw allowed it to move backwards and forwards, as well as up and down. Smaller prey could be worked backwards towards Staurikosaurus’s throat, aided along by its small, backwards-curving teeth. This feature was common in theropods of its time, but would disappear in later theropods.
