Zhuchengtyrannus[2] | Z. magnus | Shandong, China | Wangshi Series | A partial skull | A tyrannosaurine tyrannosaurid about the size of Tarbosaurus. Zhuchengtyrannus can be distinguished from all other tyrannosaurines by a single autapomorphy, the presence of a horizontal shelf on the lateral surface of the base of the ascending process of the maxilla, and a rounded notch in the anterior margin of the maxillary fenestra. Zhuchengtyrannus also possesses a ventral margin of the antorbital fenestra that lies well above that of the ventral rim of the antorbital fossa. Additionally, the total length of the maxillary fenestra is more than half the distance between the anterior margins of the antorbital fossa and fenestra. Unlike the contemporaneous Tarbosaurus, Zhuchengtyrannus lacks a subcutaneous flange on the posterodorsal part of the jugal ramus of the maxilla, and a ventrally convex palatal shelf that covers the bulges of the roots of the rear teeth in medial view. | |
