Potentially, Aetosauroides is one of the oldest aetosaurs currently known, and is comparable in age to other genera such as Stagonolepis and Aetobarbakinoides. In fact Aetosauroides has been suggested to be a synonym to Stagonolepis on more than one occasion, though the wider consensus is that it is actually a separate genus. As an aetosaur, Aetosauroides would have been a squat quadrupedal reptile that had a covering of bony osetoderm armour along its back to protect it from the teeth of predators.
