Fossil representation: Partial post cranial skeleton that was partially articulated.

       Aetobarbakinoides is considered to be one of the oldest aetosaurs currently known to us.‭ ‬Only Aetosauroides from Argentina and Stagonolepis from Scotland can match Aetobarbakinoides for age,‭ ‬but together they show that even in the earliest known appearances of aetosaurs,‭ ‬they were already widespread across what would become South America and Europe.
       Aetobarbakinoides is the first aetosaur that has been named from a description focused upon something else other than the appearance of the osteoderm armour.‭ ‬Instead of the armour,‭ ‬the description of Aetobarbakinoides was based upon the appearance of the vertebrae.‭ ‬Although the vertebrae of Aetobarbakinoides are noted to bear similarities with the vertebrae of Desmatosuchus,‭ ‬they are still very different to any other currently known aetosaur.
       In life Aetobarbakinoides would have been like other aetosaurs in that it would have been a squat quadrupedal reptile that was protected from the teeth of predators by an arrangement of osteoderm armour across the back.‭ ‬Although the skull of Aetobarbakinoides is unknown at the time of writing,‭ ‬other aeotsaurs are known to have been herbivorous without any exceptions known so far,‭ ‬so by association Aetobarbakinoides probably had a herbivorous diet.
