Eryopidae were a group of medium to large amphibious temnospondyls, ^[2] known from North America and Europe. They are defined as all eryopoids 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 previously included in the Eryopidae (Carroll 1988) are retained under the cladistic revisions.
