Prionosuchus is a large carnivorous Temnospondyl amphibian from middle Permian Brazil. It is known as the largest amphibian that ever lived; so far. It is presumed that the Prionosuchus had external gills similiar to modern Axolotl, but it is unknown if the animal truly did possess such a trait. Prionosuchus grew from 8 to 10 metres in length and weighed over 2 tons. This giant carnivore would, likely, have preyed on various fish and land vertebrates that were unfortunate enough to drink from the water Prionosuchus was waiting in with open jaws and over 60 razor sharp teeth. Prionosuchus would have laid its eggs in water like modern day amphibians but would have behaved very much like a modern day indian gharials (Gavialis gangeticus), but far much bigger and speculatively, more aggressive. Due to its smaller limbs, it would have spent much of its time in water waiting for its food to come take a drink. Due to its large size, it would have been able to take nearly anything that came near its lake.

Its speculated that the animal would have acted like Crocodilian species; by sitting at the bottom of its lake and waiting with jaws open for a fish to swim by unaware of the monsters presence then it would have closed its jaws with tremendous speed since its slender, elongated rostrum would have little to no water resistance, trapping the fish then eating it at its leisure.

In the Media

Prionosuchus is featured in Jurassic World: The Game as a Legendary amphibian.
