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