Diagnosis
ReferenceDiagnosis
X.-C. Wu et al. 2020It differs from other tyrannosauroids in the following combination of derived characters: (1) in lateral view, the interfenestral strut (between the antorbital fenestra and maxillary fenestra) is broad and covers more than 85% of the cranio-caudal length of the maxillary fenestra; (2) in lateral view, the ventral part of the antorbital fossa, ventral to the antorbital fenestra at the point just posterior to the tooth row is deeper than the subcutaneous surface below it; (3) the posteroventral end of the promaxillary recess on the medial surface stops above the fifth maxillary alveolus; (4) in medial view, the narrow septum between the promaxillary recess and maxillary antrum becomes broad ventrally and bears a small but deep fossa on its base: (5) in medial view, the anterior part of the maxillary antrum is nearly as large as the maxillary fenestra; (6) in lateral view, the dorsal row of the dentary foramina extends along the midheight of the dentary; (7) both anterior and posterior carinae bear a similar number of denticles per unit length (about 16 measured from the middle section of the tooth crown) in the maxilla and dentary teeth; and (8) the well-developed posterior process of the pubic foot forms an acute angle (about 70°) relative to the shaft of the bone.
