Diagnosis
ReferenceDiagnosis
T. Tortosa et al. 2014Majungasaurinae are defined by the combination of the following synapomorphies: (1) an antorbital fenestra anteroposteriorly expanded, (2) a parietal forming an anteriorly widening triangular plate associated with an elevated posterior narrow sagittal crest [also present in Carnotaurus (Bonaparte and Novas, 1985; Paulina Carabajal, 2011a), but lower in other brachyrostrans suc has Aucasaurus (Paulina Carabajal, 2011b), Abelisaurus (Bonaparteand Novas, 1985; Paulina Carabajal, 2011b), and Ekrixinatosaurus(Novas, 2009)]; (3) two foramina for the middle cerebral vein lying close to the sagittal plane and located on both sides of the supraoccipital crest; (4) an occipital condyle with a wide dorsal groove
