K. Carpenter 1992(Cranial) Premaxillary contacts nasal below external nares; macrymal horn often better developed than in Tyrannosaurus, and the postorbital considerably smoother; posterior part of the dentary not as deep as in Tyrannosaurus. (Postcranial) Wrist composed of five elements. Postacetabular blade of ilium deep, and pubic shaft straight.
T. D. Carr 2010Tyrannosaurid that possesses a narrow in- terfenestral strut of the maxilla; a medial pneumatic recess in the lacrimal; a large posterior pneumatic recess in the palatine, which is deeper than the anterior recess and is at least as deep as the maxillary ramus; a deep choanal process of the palatine.
