Anaschisma is a poorly known genus of prehistoric amphibian, from the Late Triassic (Carnian age) of the American Southwest, first described from the Popo Agie Formation of Wyoming. In one early cladistic analysis it appears as an advanced or highly derived form.[1] Some specimens attributed to Anaschisma sp. belong to Apachesaurus [2]
