Zhuchengtyrannus

Zhuchengtyrannus (meaning "Zhucheng tyrant") is a genus of tyrannosaurid theropod dinosaur known from the Campanian stage of the Late Cretaceous of Shandong Province, China. It belongs to the tyrannosaurinae subfamily, and contains a single species, Zhuchengtyrannus magnus.

Zhuchengtyrannus was a large carnivorous theropod, and the holotype has been estimated to have been 10–12 m (33–39 ft) in length and up to 6 short tons (5.4 t) in weight. The holotype dentary is slightly smaller than that of most specimens of Tyrannosaurus rex and slightly bigger than most of Tarbosaurus bataar, but significantly smaller than the corresponding bones of one of the largest Tyrannosaurus specimens ("Sue"). In 2016 Molina-Pérez and Larramendi estimated the (ZCDM V0030) specimen at 9.6 meters (31.5 feet) long, 2.9 meters (9.5 feet) tall at the hips and 4 tonnes (4.4 short tons) in weight.
