Zhuchengtyrannus (meaning "Zhucheng tyrant") is an extinct genus of carnivorous theropod dinosaur from the Late Cretaceous period. It is a tyrannosaurine tyrannosaurid which lived during the Late Cretaceous period in what is now Zhucheng, Shandong Province of China. It is known from a maxilla and associated dentary (lower jaw with teeth) recovered from the Wangshi Group, dating to about 73 million years ago. It measured about 11 m (36 ft) in length and 4 metres (13 ft) in height. The dentary is only slightly smaller than some of the largest known Tyrannosaurus rex jawbones,but significantly smaller than the corresponding bones of the huge Tyrannosaurus fossil "Sue".The dinosaur was found in an area that was a floodplain in the Cretaceous period and which contains one of the highest concentrations of dinosaur bones in the world.

Classification and namingEdit

Zhuchengtyrannus was first named by David W. E. Hone, Kebai Wang, Corwin Sullivan, Xijin Zhao, Shuqing Chen, Dunjin Li, Shuan Ji, Qiang Ji and Xing Xu in 2011 and the type species is Zhuchengtyrannus magnus. The generic name is derived from the word Zhucheng which refers to the type locality, and tyrant. The specific name magnus meaning "great" in Latin refers to the relatively large size of Zhuchengtyrannus.

It is possible that several isolated teeth from the same quarry, previously given the name Tyrannosaurus zhuchengensis, belong to this or a related species. The T. zhuchengensis teeth are characterized by serrations which extend all the way to the base of the tooth crown, a feature not seen in any other tyrannosaurine species. All known teeth of Zhuchengtyrannus are too poorly preserved in this area to compare with T. zhuchengensis, but further finds may clarify their relationship.
