Artist Portia Sloan worked with the Chinese scientists who discovered the new dinosaur to produce this drawing of what it might have looked like.

Scientist Xu Xing and colleagues found the tyrannosauroid, an early relative of T. rex, in Liaoning province in China. The species, named Dilong paradoxus, provides the first direct fossil evidence that tyrannosauroids had hairlike primitive feathers.

This research was supported in part by the National Geographic Society's Committee for Research and Exploration.
