}}Aetosaurinae is one of the two subfamilies of aetosaurs, the other being Desmatosuchinae. It is a stem-based taxon defined as all aetosaurs more closely related to Aetosaurus than to the last common ancestor of Aetosaurus and Desmatosuchus.[1] The only synapomorphy that diagnoses the clade Aetosaurinae is the medial offset of the dorsal eminences of the paramedian osteoderms.[2] A phylogenetic study in 2012 found Aetosaurinae to be paraphyletic, with Aetosaurus being the basal-most stagonolepidid and aetosaurines like Calyptosuchus, Neoaetosauroides, and the newly described Aetobarbakinoides being successively more derived taxa leading up to a clade containing Desmatosuchinae and Typothoracisinae. Under this phylogeny, most traditional aetosaurines are more closely related to Desmatosuchus than they are to Aetosaurus, and the clade Aetosaurinae can only include Aetosaurus.[3] References1. ^{{cite journal |last=Heckert |first=A.
