Eryopoidea are a taxon of late Carboniferous and Permian temnospondyli amphibians, known from North America and Europe. Carroll includes no less than ten families,[1] but Yates and Warren replace this with a cladistic approach and include only two Permian families, the Eryopidae and Zatrachydidae.[2] 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.[3]
