Line 17:

'''Eryopoidea''' are a taxon of [[Pennsylvanian|late Carboniferous]] and [[Permian]] [[temnospondyli]] amphibians, known from North America and Europe. Carroll includes no less than ten families,<ref>{{cite book | author = [[Robert L. Carroll|Carroll, R. L.]] | year = 1988 | title = Vertebrate Paleontology and Evolution | publisher = W.H. Freeman & Co.}}</ref> but but Yates and Warren replace this with a cladistic approach and include only two Permian families, the [[Eryopidae]] and [[Zatracheidae]].<ref>{{cite journal | author = [[Adam Yates|Yates, A. M.]] & [[Anne Warren|Warren, A.

Linnean Soc. | volume = 128 | pages = 77-121}}</ref> 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.<ref>{{cite web | author = [[Michel Laurin|Laurin.
