Shirerpeton is an extinct genus of albanerpetonid amphibian from the Early Cretaceous Kuwajima Formation, which is located in Japan.[1] The type species is Shirerpeton isajii, which was described by Masumoto & Evans in 2018.[2] Shirerpeton represents the first record of Albanerpetontidae in East Asia and the holotype is SBEI 2459, a small block bearing most of a disarticulated but associated skull with some postcranial elements present aswell.[2] Shirerpeton probably had a ballistic tongue akin to that of a chameleon.[3][4]
