According to our research, R

The first around three profile claims reinforce the articulations involving the face facets from the mouth musculature (Schumacher, 1973 ). The region of your abducens bravery foramen is actually originally hypothesized since the a possible synapomorphy help a crocodylomorph + aetosaur clade personal regarding other pseudosuchians (Gower, 2002 ), but newer phylogenetic analyses, along with ours, suggest this apomorphy advanced at least twice-just after inside aetosauriforms as soon as into the crocodylomorphs. But not quantified within this analysis, a great dorsoventrally thickened head rooftop (we.e., nasals, frontals, and you can parietals) is also common of the R. callenderi, erpetosuchids, and aetosaurs.

callenderi and you can aetosaurs share parallels throughout the dimensions of the latest hindlimb to help you forelimb and you can shape of the newest humerus and you may proximal foot factors, regardless if men and women parallels weren’t unambiguous synapomorphies. Read more
