Diagnosis
ReferenceDiagnosis
D. W. E. Hone et al. 2011A large tyrannosaurine theropod dinosaur distinguished from other tyrannosaurine taxa by the following features of the maxilla: 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. Zhuchengtyrannus magnus also possesses the following unique combination of characters: the ventral margin of the antorbital fenestra lies well above that of the ventral rim of the antorbital fossa, and the anteroposterior length of the maxillary fenestra is more than half the distance between the anterior margins of the antorbital fossa and fenestra.
Zhuchengtyrannus magnus can be distinguished from the contemporaneous Asian tyrannosaurine Tarbosaurus bataar by the absence of a subcutaneous flange on the posterodorsal part of the jugal ramus of the maxilla, and the absence of a ventrally convex palatal shelf that covers the bulges of the roots of the posterior teeth in medial view.
