Field notes

About Zhenyuanlong

What it was like

Zhenyuanlong was a feathered dromaeosaur, a relative of Velociraptor. Its single skeleton is nearly complete and shows large wing feathers on its short arms and long feathers on its tail. It was too heavy to fly, so its wings may have been for display or for keeping eggs warm.

Its world

It lived in the Early Cretaceous, in what is now China. The Yixian Formation it comes from was a land of lakes and forests, often buried by volcanic ash. It shared that world with the feathered tyrannosaur Yutyrannus, the small hunters Sinosauropteryx and Sinornithosaurus, and the plant eater Psittacosaurus.

How it was found

Lü and Brusatte named Zhenyuanlong in 2015. The name ends in the Chinese word for dragon.
