context_page_description: Zhuchengtyrannus is a genus of tyrannosaurid theropod dinosaur known from the Late Cretaceous period of Shandong Province, China. It belongs to the tyrannosaurinae subfamily, and contains a single species, Zhuchengtyrannus magnus.
context_section_description: It is possible that several isolated teeth from one of the Zhucheng dinosaur quarries, previously given the name Tyrannosaurus zhuchengensis, belong to this or a related species. The T. zhuchengensis teeth are characterized by serrations that 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.
  
  A phylogenetic analysis published with the description of the tyrannosaurine Lythronax in the journal PLOS One by Loewen et al. 2013, recovered Zhuchengtyrannus as the sister taxon of Tarbosaurus. It also suggests that Zhuchengtyrannus and other currently known Asian tyrannosaurids were part of an evolutionary radiation descending from the same North American stem that later gave rise to Tyrannosaurus, recovered as their closest known relative. Below are the results obtained in their phylogenetic analysis:
