Diagnosis
ReferenceDiagnosis
R. A. Coria et al. 2002Two unambiguous synapomorphies support the monophyly of carnotaurs (term used to refer to members of the Carnotaurini): the presence of hyposphene–hypantrum articulations in the proximal and middle sections of the caudal series, and cranial processes in the epipophyses of the cervical vertebrae. Several other synapomorphies provide further support for the monophyly of carnotaurs. These, however, are ambiguously optimized because they are not preserved in other abelisaurs. These ambiguous synapomorphies include: a very broad coracoid (coracoid maximum width three times the distance across the scapular glenoid area), a humerus with a large and hemispherical head, an extremely short ulna and radius (ulna to humerus ratio 1:3 or less), and frontal prominences (swells or horns) that are located laterally on the skull roof.
