In Depth 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 … Read more
