       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. There is a high degree of size variation amongst Aetosauroides specimens ranging from a little over a meter to just over two meters. There is speculation that this size difference maybe down to sexual dimorphism, with males being larger than females.
