Diagnosis
ReferenceDiagnosis
M. T. Carrano et al. 2012Megalosauroids possessing the following synapomor phies: (1) two parallel rows of nutrient foramina on lateral surface of maxilla (21(1)); also in Eocarcharia and Shaochilong); (2) vertically striated or ridged paradental plates (140(1)); also in abelisaurids, Megalosaurus and Proceratosaurus); (3) reduced axial parapophyses (166(1)); also in coelophysoids, Eustreptospondylus and Afrovenator); (4) anteriorly inclined posterior dorsal neural spines (192(1)); in parallel with Allosauroidea); and (5) canted distal humeral condyles (236(1)); also in Poekilopleuron, Allosauridae and Fukuiraptor). In addition, among tetanurans these taxa show reversals to the primitive condition for the following features: (1) a short or absent anterior maxillary ramus (12(0)); (2) moderate development of axial diapophyses (167(0)); and (3) no axial pleurocoels (168(0)).
