Guanlong is a proceratosaurid theropod dinosaur from the Late Jurassic of China. It was named in 2006 by Xu Xing and his crew. It was a small theropod notable for being one of the earliest ancestors of the famous Tyrannosaurus, as well as having a large crest.


Guanlong was a small theropod with a slender body, a long tail, long arms with three fingers on each hand, a moderately long neck, a long, conical head with large jaws, and a large, oval-shaped crest atop its head. Most of its body (excluding some of its legs and all of its snout) would have been covered in short, fuzz-like feathers.


Guanlong was a predator, preying on lizards, small mammals, pterosaurs, small ornithischians, and smaller theropods. Its teeth had knife-like serrations from front to back, and were used to cut into the hides of large prey.


So far, all we know about Guanlong is that it had a large, likely flamboyant crest atop its head, used for display; whether it was used for attracting mates or for recognition by other members of its species is unknown.

In popular cultureEdit

Guanlong was featured in the 2009 adventure movie Ice Age: Dawn of the Dinosaurs, where a pack of the proceratosaurids harasses Manny the woolly mammoth and his friends while they try to traverse an unbalanced, rocky field; interestingly enough, the director states that Guanlong was supposed to be a substitute for the famous Velociraptor, a small dromaeosaurid often featured in films as a vicious, pack-hunting menace. It was once again featured in the 2011 documentary Dinosaur Revolution, where a hungry pair of the theropods try to eat any small mammal they could find in the Jurassic forests.
