}}Discosauriscidae is a family of stegocephalians from the early Permian. They belong to the Seymouriamorpha, but their affinites to extant tetrapods are debated. They have long been considered reptiliomorphs,[2] but some recent analyses suggest that they are stem-tetrapods.[3] References1. ^Klembara, J. (2009).
