Diagnosis
ReferenceDiagnosis
H. Zaher et al. 2020Spectrovenator ragei n. gen., n. sp. differs from all other abelisaurid theropods by the following unique autapomorphies: posterior ramus of maxilla ornamented with vertically oriented grooves except for the smooth region anterior to the maxilla-jugal suture; lacrimal lateral surface rugose except for smooth ventral region; ventrally bowed posterior process of jugal; nuchal crest with thin and smooth dorsal margin; straight ventral margin of dentaries with deep sulcus on lateral surface; dorsal margin of surangular slightly convex; longitudinal ridge along posteroventral end of mandibular ramus.
