Aetosauroides (meaning "Aetosaurus-like") is an extinct genus of aetosaur from the Late Triassic of South America. It is one of three aetosaurs known from South America, the others being Neoaetosauroides and Chilenosuchus. Two species have been named: the type species A. scaglia and a second called A. subsulcatus.
Aetosauroides was proposed to be synonymous with the genus Stagonolepis in 1996 and 2002.[1][2] Smaller specimens of both species were placed with Stagonolepis robertsoni, and larger specimens were considered to be S. wellesi. This synonymy is not entirely accepted, with several studies identifying unique features that distinguish Aetosauroides from Stagonolepis. Among these are maxillae that do not touch the nostrils, oval-shaped holes on the centra of the vertebrae, and a convex margin of the lower jaw. In a 2011 study, A. subsulcatus was proposed to be synonymous with A. scaglia.[3]
