The Guanlong, sometimes referred to as the dragon, was a carnivore theropod dinosaur from the Late Jurassic period. The Guanlong dinosaur resembles a tyrannosaur and was considered too primitive, or early, for their own kind to be discovered. The name Guanlong is a Chinese word that means 'crown dragon'.
The Guanlong name discovery credit is given to Xu Xing, Clark, Forster, Norell, Erickson, Eberth, Jia, and Zhao in 2006. It was discovered by a scientist team from George Washington University and the Institute of Vertebrate Paleontology and Paleoanthropology.
They found that the dinosaur was a partially articulated adult, almost juveniles, from the two specimens description one being the holotype IVPP V14531 and the other specimen from the fully articulated complete remains.
The two specimens were dated back to the Oxfordian stage of the Shishugou Formation near the Dzungaria region in China. It is believed that these dinosaurs existed 163-158 million years ago.
They preyed on small dinosaurs, animals, and mammals. They were often compared to Tyrannosaurs rex on the basis of their food habits. These tyrannosaurs had larger arms and a large crest on their skull compared to later tyrannosaurs.
