Pholiderpeton

Pholiderpeton (from Greek: φολῐ́δοςfolĭdos, 'horny scale' and Greek: ἑρπετόνherpetón, 'creeping thing') is an extinct genus of embolomereamphibian which lived in the Late Carboniferousperiod (Bashkirian) of England. The genus was first named by Thomas Henry Huxley in 1869 to include the species P. scutigerum, based on the disarticulated front half of a skeleton discovered near Bradford, Yorkshire.

In 1987, Jennifer A. Clack suggested that a different embolomere, Eogyrinus attheyi from Newsham, Northumberland, belonged to the same genus as Pholiderpeton. She subsumed the genus Eogyrinus into Pholiderpeton and created the new combination P. attheyi.

Pholiderpeton scutigerum measured 2 metres (6 ft 7 in) in length, while specimens of P. attheyi had 41 centimetres (16 in) long skull and could measure up to 4 metres (13 ft) long. The latter species was thus among the largest Carboniferous tetrapods, and perhaps one of the largest of its family, the Eogyrinidae.
