 In 2000 , paleontologists Adam Yates and Anne Warren produced a revised phylogeny of more derived temnospondyls , naming several new clades . Two major clades were Euskelia and Limnarchia . Euskelia includes the temnospondyls that were once called rhachitomes and includes two subfamilies , the Dissorophoidea and the Eryopoidea . Dissorophoids include small , mostly terrestrial temnospondyls that may be the ancestors of modern amphibians . Eryopoids include larger temnospondyls like Eryops . The second major clade , Limnarchia , includes most Mesozoic temnospondyls , as well as some Permian groups . Within Limnarchia are the superfamily Archegosauroidea and the most derived temnospondyls , the stereospondyls .
