Guanlong is a genus of extinct proceratosaurid tyrannosauroid from 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, translating as "five coloured crowned dragon". 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.
About 3 m (9.8 ft), its fossils were found in the Shishugou Formation dating to about 160 million years ago, in the Oxfordian stage of the Late Jurassic period, 92 million years before its well-known relative Tyrannosaurus. This bipedal saurischian theropod shared many traits with its descendants, and also had some unusual ones, like a large crest on its head. Unlike later tyrannosaurs, Guanlong had three long fingers on its hands. Aside from its distinctive crest, it would have resembled its close relative Dilong, and like Dilong may have had a coat of primitive feathers.
