Ceratodus. On the shores of these rivers lived labyrinthodonts (Latiscopus) and reptiles such as Malerisaurus and Trilophosaurus. Also living on the margins of the lakes were the archosaurs Leptosuchus, Nicrosaurus and Rutiodon and the dicynodont Placerias. Postosuchus lived in the uplands along with Coelophysis and other archosaurs such as Desmatosuchus and Typothorax. Postosuchus was one of the largest animals in that ecosystem and preyed on herbivores such as Trilophosaurus, Typothorax and Placerias''.
