Field Guide to the Oviraptorosaur

OviThis bizarre dinosaur is unlike any other known to science, representing a brand new species of oviraptorosaur that has yet to be named.

Oviraptorosaurs were unusual theropods (generally meat-eating dinosaurs) that lived during the Cretaceous Period, between 130-65 million years ago. Our oviraptorosaur is both the largest and the geologically youngest oviraptorosaur yet discovered.

This dinosaur has a startling array of features. It is armed with long, intimidating claws, yet it has no teeth. The bones are lightweight, but strong. The skull is capped with an unusual crest. The skeleton poses several intriguing riddles. What do these anatomical features reveal about oviraptorosaurs, a group of dinosaurs long shrouded in mystery? Where does this dinosaur fit on the evolutionary tree of life? Explore this Field Guide to learn more!
