Wesserpeton is known from the
holotype NHMUK PV R36521, nearly complete fused
frontals and from the referred materials NHMUK PV R36522–36568 and R36595–36611. All specimens were collected from seven localities of the
Wessex Formation on the southeastern coast of the
Isle of Wight of southern England. The type locality (Bed 38) is exposed at
Yaverland while the rest (Bed L2) are exposed high in the cliff at
Sudmoor Point but have yielded only NHMUK PV R36539, R36522 and R36553–36558. All specimens are dating to the
Barremian stage of the
Early Cretaceous. ==Etymology==
