Archeopelta was a quadrupedal low slung reptile with a build similar to that of a crocodile. Archeopelta also would have had armoured scutes protecting its body in a similar manner to a crocodile. As a member of the Doswelliidae, Archeopelta would have also been related to Doswellia and Tarjada. These are seen as predators of smaller animals, though their armour may have protected them from rauisuchians and the early ancestors of the dinosaurs.
- An unusual new archosauriform from the Middle–Late Triassic of southern Brazil and the monophyly of Doswelliidae, J. B. Desojo, M. D. Ezcurra & C. L. Schultz - 2011.
