In Depth

       Pelorocephalus lived towards the end of the Triassic,‭ ‬a time just before the temnospondyl amphibians declined to be only a small portion of their former selves.‭ ‬Pelorocephalus was typical of the temnospondyl body type,‭ ‬resembling a large heavily built salamander-like creature that in the instance of Pelorocephalus grew to around one meter long,‭ ‬though there is some variance between the species.‭ ‬With the land dominated by reptiles such as archosaurs,‭ ‬rausuchians and even very primitive dinosaurs,‭ ‬Pelorocephalus would have been restricted to hunting in the water where these other predators could not venture into.

       As a member of the Chigutisauridae,‭ ‬Pelorocephalus is considered to be more closely related to genera such as Compsocerops,‭ ‬Keratobrachyops,‭ ‬Koolasuchus,‭ ‬Kuttycephalus and Siderops.‭ ‬Some genera that are closely related to Pelorocephalus were some of the last temnospondyl amphibians known to have survived,‭ ‬with Siderops living in the Jurassic and Koolasuchus living in the Cretaceous.
