Oviraptosaurs

The first oviraptosaur to be discovered had a crushed skull and was lying on a nest of fossilized dinosaur eggs. The eggs belonged to an herbivore called Protoceratops. At the time of its death, the oviraptosaur was probably trying to steal the eggs to eat, and since its skull was crushed, it may have been caught and killed by an adult Protoceratops. Oviraptosaurs probably also ate berries and insects, as well as scavenging on the carcasses of dead animals.

Oviraptor philoceratops This oviraptosaur had a short head with powerful, toothless jaws. Two bony prongs pointed down from the roof of the mouth. The prongs may have been used to crush eggs or the shells of freshwater mollusks.

Oviraptosaur facts

• Oviraptosaurs i lived toward the end of the Cretaceous period.

• Their brain cavity was large, which suggests that they were intelligent.

• Skeletons have been found only in Mongolia.

Head decorations Many oviraptosaurs had tall, bony head crests. Ingenia lacked a head crest, but it might have had brightly colored skin instead.

Bony head crest

Head crests Different oviraptosaurs had differently shaped crests. A modern bird, the cassowary, has a crest to butt its way through forest undergrowth. perhaps oviraptosaurs used their crest for a similar purpose.

Cassowaries also butt their way through vegetation when escaping from predators.

Cassowary head

Slim and agile Oviraptosaurs were small and lightly built, with hollow bones. They had slim but muscular back legs and could run quite fast. Their large hands had curved fingers ending in large, grasping claws.
