Eryopidae are a family of medium to large Permian temnospondyli amphibians, known from North America and Europe. They are defined cladistically as all Eryopoidea with interpterygoid vacuities (spaces in the interpterygoid bone) that are rounded at the front; and large external nares (Laurin and Steyer 2000). Not all of the genera poreviously included in the Eryopidae (Carroll 1988) are retained under the cladistic revisions.
