Oviraptor, (genus Oviraptor), small, lightly built predatory or omnivorous dinosaur that brooded its eggs in a manner similar to birds. Found as fossils in deposits from the Late Cretaceous of eastern Asia and North America, Oviraptor was about 1.8 metres (6 feet) long and walked on two long, well-developed hind limbs. The forelimbs were long and slender, with three long clawed fingers clearly suited for grasping, ripping, and tearing. Oviraptor had a short skull with very large eyes surrounded by a bony ring; it was possibly capable of stereoscopic vision. The skull also had strange cranial crests, and the jaws lacked teeth but were probably sheathed with a horny, beaklike covering.
