This is a Guanlong
Guanlong (meaning "crowned dragon") is a genus of extinct proceratosaurid tyrannosauroidfrom the Late Jurassic of China. The taxon was first described in 2006 by Xu et al., who found it to represent a new taxon related to Tyrannosaurus. The name is derived from Chinese; when translated to English, it means something like "crowned dragon of the five colored gems". Two individuals are currently known, a partially complete adult and a nearly complete juvenile. These specimens come from the Oxfordian period, of the Chinese Shishugou Formation.
Guanlong was discovered in the Dzungaria area of China by a joint expedition by scientists from the Institute of Vertebrate Paleontology and Paleoanthropology and George Washington University, and named by Xu Xing and others in 2006. Guanlong comes from the Chinese words for "crown" and "dragon", referring to the crest. The specific epithet (äş”ĺ˝©ĺ† éľ™), wucaii (Hanyu Pinyin: wĹcái), means "five colours" and refers to the colours of rock of the Wucaiwan, the multi-hued badlands where the creature was found
