Eryopoidea are a taxon of late Carboniferous and Permian temnospondyli amphibians, known from North America and Europe. Carroll includes no less than ten families, [cite book | author = Carroll, R. L. | year = 1988 | title = Vertebrate Paleontology and Evolution | publisher = W.H. Freeman & Co.] but Yates and Warren replace this with a cladistic approach and include only two Permian families, the Eryopidae and Zatrachydidae. [cite journal | author = Yates, A. M. & Warren, A. A. | year = 2000 | title = The phylogeny of the 'higher' temnospondyls (Vertebrata: Choanata) and its implications for the monophyly and origins of the Stereospondyli | journal = Zool. J. Linnean Soc. | volume = 128 | pages = 77–121] They define the Eryopoidea as all Euskelia in which the choana are relatively rounded and the iliac blade vertical. A similar definition but without the Euskelia is provided by Laurin and Steyer. [cite web | author = Laurin. M and Steyer, J-S | year = 2000 | url = http://tolweb.org/tree?group=Temnospondyli | title = Phylogeny and Apomorphies of Temnospondyls - Tree of Life project]
