Zhenyuanlong (jhen-wahn-long)

Zhenyuanlong (meaning "Zhenyuan's dragon" from Chinese Pinyin; 龙 Lóng means dragon) is an extinct genus of dromaeosaurs that existed during the early Cretaceous period in what is now China.

This type specimen preserved a nearly complete skeleton missing half of the tail, but containing traces of feathers, including long tail feathers and large wings.

It is known from a single specimen belonging to the species Zhenyuanlong suni.


Zhenyuanlong suni was a mid-sized dromaeosaurid comparable in length to the similar Tianyuraptor. It was perhaps up to 2 meters (6.6ft) in life. It had short arms compared to the size of its body and had a fan of long feathers on them, like wings. It's currently the largest non-avian dinosaur with complex feathers known.

The only specimen of Zhenyuanlong was found by a farmer near Sihedang in Jianchang, Liaoning Province in China. It was later studied at the Jinzhou Paleontological Museum. There, the type species was also named and described by paleontologists.
