ABSTRACT Silvanerpeton miripedes gen. et sp. nov. is a small gracile anthracosauroid. The holotype is an almost complete articulated specimen in black shale. Its anthracosaur characters include tabular-parietial contact, with a tabular horn and a moderate surangular crest indicating relationship with the embolomeres. It has gastrocentrous vertebrae with poorly ossified centra and neural arches, and the presacral vertebral count is estimated to be over 30. There are a number of apparently primitive characters as found in other anthracosauroids include a closed palate, mobile basal articulation, and an intertemporal. It differs from the other recognised species of anthracosaur at East Kirkton, Eldeceeon rolfei, in vertebral count, number of ribs, interclavicle shape, relative limb length, and in having an unossified tarsus, and a pedal phalangeal count of 23455. Disarticulated bones from East Kirkton including large limb and vertebral elements may belong to this taxon, to Eldeceeon rolfei or to as yet unidentified taxa.
