Abstract

Previously thought to be a salamander (Prosirenidae), Albanerpeton Estes and Hoffstetter (Jurassic to Miocene) possesses no known features otherwise restricted to salamanders. Its salamander-like features are only those held in common with small, limbed, non-saltatorial amphibians in general. In still other aspects (including feeding apparatus, dermal bones of the skull, and anterior cervical vertebrae), Albanerpeton appears unique. Already well isolated from salamanders, Albanerpeton seems no nearer phyletically to any other known amphibians, from Devonian to Recent. The relationships of Albanerpeton are most consistently indicated by classification in its own family (Albanerpetontidae, new) and order (Allocaudata, new), perhaps referrable to the Lissamphibia.
