Diagnosis

---|---|---|
M. T. Carrano et al. 2002 | Abelisauroid theropod with anterior four dentary teeth procumbent, the first inclined at 10° above the horizontal and lying in an alveolus that is slung below the ventral margin of the dentary. First alveolus large and ventrally expanded, lying lateral to an anteroposteriorly long dentary symphysis. Lower dentition markedly heterodont: the first four teeth are weakly spoon-shaped, elongate, and terminate in a posteriorly hooked, pointed apex. Anterior dentary teeth bear two weakly serrated posterior carinae and have faint posterior ridges; more posterior teeth are transversely compressed, recurved, and have a serrated posterior carina. | |
M. T. Carrano and S. D. Sampson 2008 | Abelisauroid with: (1) four most anterior dentary teeth procumbent, with the first set in a large, ventrally expanded alveolus that is almost horizontal in orientation, (2) a strongly heterodont lower dentition, grading from elongate, weakly serrated, apically round with labiolingually positioned carinae (anteriorly) to increasingly recurved, transversely compressed, with mesiodistally positioned carinae (posteriorly) (modified from Sampson et al. 2001: 504). | |
M. T. Carrano et al. 2012 | Abelisauroid with: (1) four anteriormost dentary teeth procumbent, with first set in large, ventrally expanded alveolus that is almost horizontally oriented; and (2) strongly heterodont lower dentition, grading from elongate, weakly serrated, apically round teeth with labiolingually positioned carinae (anteriorly) to increasingly recurved, transversely compressed teeth with mesiodistally positioned carinae (posteriorly) (all from Sampson et al. 2001). |
