Diagnosis
ReferenceDiagnosis
J. B. Desojo et al. 2012Medium-sized aetosaur (around 2 meters in total length) distinct from other archosaurs by the following combination of characters (autapomorphies indicated by an asterisk): cervical vertebrae with prezygapophyses widely laterally extended through most of the anterior edge of the diapophysis* and with hyposphene; midcervical vertebrae with anterior articular facet width more than 1.2 times wider than the posterior one* and without ventral keel; anterior and mid-dorsal vertebrae without lateral fossa in the centrum, and postzygapophyses mainly posteriorly projected; anterior caudal vertebrae with extremely anteroposteriorly short prezygapophyses*; elongated humerus and tibia in relation to axial skeleton (including humerus with a length/transverse width at midlength ratio greater than 12)*. The paramedian osteoderms of Aetobarbakinoides present a radial ornamentation composed of grooves and pits and with a weakly raised anterior bar. This osteoderm morphology is also exhibited by Paratypothorax and Rioarribasuchus, but Aetobarbakinoides differs from these taxa in the presence of proportionally transversely narrower and strongly ventrally flexed paramedian osteoderms.
