''Zhuchengtyrannus'' (meaning "Zhucheng tyrant") is an extinct genus of large carnivorous theropod dinosaur known from the Late Cretaceous period of Shandong Province, China. It is a tyrannosaurine tyrannosaurid, and contains a single species, ''Zhuchengtyrannus magnus''. ==Discovery==
''Zhuchengtyrannus'' was first described and 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'' in reference to its phylogenetic position as a tyrannosaurid. The specific name ''magnus'' meaning "great" in Latin refers to the relatively large size of ''Zhuchengtyrannus''.〔 ''Zhuchengtyrannus'' is known solely from the holotype ZCDM V0031, a nearly complete right maxilla and associated left dentary (lower jaw, both with teeth) housed at Zhucheng Dinosaur Museum. Casts of the holotype, IVPP FV 1794, are held at the Institute of Vertebrate Paleontology and Paleoanthropology. ZCDM V0031 was collected in situ from the Wangshi Group at Zangjiazhuang quarry, Zhucheng City, dating to the Campanian stage, at least 73.5 million years ago. A second tyrannosaurid dentary (ZCDM V0030) and maxilla (ZCDM V0032) have also been collected at Zangjiazhuang quarry. Even though they were not associated with one another, both specimens are different from other tyrannosaurids, including ''Zhuchengtyrannus'', implying the existence of at least one additional tyrannosaurid from the quarry. Apart from the tyrannosaurid material, specimens of ''Sinoceratops'', hadrosaurids (probably ''Shantungosaurus'') and ankylosaurs were recovered from it.〔 ''Zhuchengtyrannus'' was found in an area that was a floodplain in the Cretaceous period and contains one of the highest concentrations of dinosaur bones in the world.
