Named By: Cabrera - 1944.
Classification: Chordata, Amphibia, Temnospondyli, Stereospondyli, Chigutisauridae.
Species: P. mendozensis, P. cacheutensis, P. ischigualastensis, P. tenax.
Size: About 1 meter long.
Known locations: Argentina.
Time period: Carnian of the Triassic.
Fossil representation: Many individuals.
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
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.
