Albanerpeton

 Albanerpeton is an extinct genus of salamander-like lissamphibian found in North America and Europe. Members of the genus had a robust head and neck which likely allowed them to actively burrow, and they lived in a wide range of environments. This genus of amphibian was the last of its order, surviving until the late Pliocene in southern Europe, and likely went extinct when the region developed its present Mediterranean-type climate.

 Albanerpetontodae is an extinct family of superficially salamander-like lissamphibians. Albanerpetontids include four genera - Albanerpeton, Anoualerpeton, Celtedens, and Wesserpeton - and between 10 and 20 known species, spanning about 160 million years from the Bathonian stage of the Middle Jurassic to the end of the Pliocene. Albanerpetontids were long thought to be salamanders because of their small size and generalized body plans. However, these features are now thought to be ancestral for lissamphibians and not indicative of close relationships between the two groups. Albanerpetontids are now recognized as a distinct clade of lissamphibians separate from the three living orders of amphibians - Anura (frogs), Caudata (salamanders), and Gymnophiona (caecilians). They are thought to be more closely related to frogs and salamanders than to caecilians.
