Eoherpeton watsoni

Eoherpeton watsoni is known from a single crushed skull from the Lower carboniferous of Scotland which was initially attributed by Watson in 1929 to the species Pholidogaster pisciformis. However, Panchen reexamined the skull and erected the new genus Eoherpeton in 1975. Eoherpeton was a rather large (skull measured 15 cm thus a total length estimate of 1 m) early tetrapod of uncertain affinities. It was classified as an Anthracosaur, an Embolomeri, a Gephyrostegid, but can be neither of them.
