Diagnosis
ReferenceDiagnosis
A. W. A. Kellner and D. d. A. Campos 1996Theropod dinosaur with anterior part of the skull strongly compressed laterally, narrowest near the 6th premaxillary tooth; anterior portion of premaxilla less broad ("spoon-shaped") than in Baryonyx; and a well developed premaxillary sagittal crest.
M. T. Carrano et al. 2012Spinosaurid with midline ridge on dorsal surface of conjoined premaxillae extending further anteriorly than in Baryonyx and Suchomimus (modified from Kellner & Campos 1996). Angaturama cannot currently be distinguished from Irritator because it is based on non-overlapping skull material.
