An illustration of Wesserpeton by Mark Witton, depicting hypothetical territorial behavior

Wesserpeton was a genus of albanerpetonid amphibian from the Cretaceous of England.


Like other albanerpetonids, Wesserpeton resembled a small salamander in its morphology. Unlike modern amphibians, however, albanerpetonids had scaly skin that prevented dessication. Wesserpeton itself measured about 35 centimeters in length from snout to vent.[1]


Wesserpeton was a type of albanerpetonid amphibian. Originally, they were thought to be a type of salamander,[2] but it is now believed that they are not part of any extant group of amphibian.[3]


Wesserpeton evansae was described in 2013 by Steven Sweetman and James Gardner after being discovered in Cretaceous rocks from the Isle of Wight.[4]


Many jaws of Wesserpeton show signs of trauma, and it is possible that this is due to intraspecific competition.[5][6] Similar behavior exists in modern salamanders.[7]
