In Depth Polesinesuchus is one of a growing number of aetosaur genera that are steadily being discovered from Triassic aged rock formations in South America. Polesinesuchus is a stagonolepid aetosaur, meaning that it was more similar to genera such as Stagonolepis. Further Reading - A new aetosaur from the Upper Triassic of the Santa Maria … Read more
In Depth Stagonolepis had the typical aetosaur body form, quadrupedal, short legs and osteoderms than ran down the length of the body. This form could be described as crocodile-like, but caution should be exercised before assuming that Stagonolepis lived like a crocodile as well. Stagonolepis had neither piercing or slicing teeth, but peg-like teeth adapted … Read more
In Depth Coahomasuchus is a genus of aetosaur that lived in North America during the late Triassic. Like relatives, Coahomasuchus had plate like osteoderms that ran down the length of the back and under the throat. With a length of about one and a half meters, Coahomasuchus is one of the smaller aetosaurs. Further Reading … Read more
In Depth Desmatosuchus is one of the better known aetosaurs that were squat quadrupedal archosaurs that fed upon low growing vegetation. This diet is suggested by the presence of peg like teeth that were best suited for stripping off fronds of fern-like vegetation. Not only is Desmatosuchus one of the better known of its group … Read more
In Depth 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 … Read more
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
