Ariekanerpeton is an extinct genus of seymouriamorph from the lower Permian. Fossils have been found from Tajikistan representing over 900 individuals of various stages of ontogenic development.[1] However, it is thought that none of these specimens are of fully mature animals as poor bone ossification is present and the neural arches are paired and disarticulated from the pleurocentra.[2]
Ariekanerpeton is thought to have been more closely related to Discosauriscus and Seymouria than to Utegenia due to the absence of gastralia or a postorbital-supratemporal contact. However, it is not a member of the family Discosauriscidae or the family Seymouriidae. There are no dermal scales present on post-metamorphic specimens as there are on Discosauriscus.[3] Lateral lines are present in the skulls of larval individuals but are lost soon after metamorphosis. Unlike Utegenia and Discosauriscus, Ariekanerpeton is thought to have inhabited relatively arid environments.[4]
