Keraterpeton

Keraterpeton is an extinct genus of lepospondyl amphibian from the Carboniferous period of Europe and North America.

Keraterpeton was a salamander-like creature about 30 centimetres (12 in) long. Its tail was remarkably long taking up two thirds of the animal's total length, and was laterally flattened, presumably to aid in swimming. Its skull was round and short, especially when compared to its Permian relative, Diplocaulus. Its hind legs had five toes, and were longer than the forelimbs, which had only four toes.
