description Guanlong wucaii Overview

Guanlong wucaii was a small, early tyrannosauroid theropod that lived in what is now northwestern China during the Late Jurassic, about 160 million years ago. It is distinguished by a large, thin crest along the top of its skull, a structure generally interpreted as ornamental rather than suited to combat. Guanlong helps document the early history of the tyrannosaur lineage, long before its later members evolved very large bodies and massive skulls.
