Oviraptor was a small, lightly built predatory or omnivorous dinosaur that brooded its eggs in a manner similar to birds. It lived in the Late Cretaceous Period, about 100 million to 65 million years ago, in eastern Asia. It was about 1.8 metres 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 and tearing. The skull had a large and peculiar cranial crest and the jaws lacked teeth, but were probably sheathed with a horny, beak-like covering, effective for feeding on hard objects, such as seeds or cracking eggs.
