K. Carpenter 1992(Cranial) Premaxilla does not contact nasals under external nares; lacrymal horn well developed; postorbital rugose, although less than Tyrannosaurus; pro-maxillary fenestra very small; surangular foramen very large. (Postcranial) Postacetabular blade of ilium very long; ischium straight; scapula broadens gradually posteriorly; acromion process of scapula forms a continuous arc with the coracoid.
