Al igual que su 'primo', el mítico Tiranosaurio rex, era un depredador temible con potentes mandíbulas, enormes patas traseras y unos brazos proporcionalmente diminutos. Medía cuatro metros de altura, 11 metros de la cabeza a la cola y pesaba seis toneladas. Así era el 'Zhuchengtyrannus magnus', una nueva especie de dinosaurio carnívoro cuyos restos fosilizados se han descubierto en China.

Abstract
Tyrannosaurids are primarily gigantic, predatory theropod dinosaurs of the Cretaceous. Here we report a new member of the tyrannosaurid clade Tyrannosaurinae from the Upper Cretaceous Wangshi Group of Zhucheng, Shandong Province, China, based on a maxilla and associated dentary. The discovery of this animal, here named Zhuchengtyrannus magnus gen. et sp. nov., adds to the known diversity of tyrannosaurids in Asia. Z. magnus can be identified by a horizontal shelf on the lateral surface of the base of the ascending process, and a rounded notch in the anterior margin of the maxillary fenestra. Several additional features contribute to a unique combination of character states that serves to further distinguish Z. magnus from other taxa. Comparisons with other tyrannosaurids suggest that Zhuchengtyrannus was a very large theropod, comparable in size to both Tarbosaurus and Tyrannosaurus.

Siendo made in China seguro que vivían menos y peor que los originales
