A possible close relative of the genus Cacops, Aspidosaurus is noted for having a single row of bony armour plates than ran down its spine. Aspidosaurus had fairly slender teeth that were the same size throughout the mouth. These were probably used to seize small animals such as fish, amphibians and possible early reptiles.
