Eryopidae

Eryops (; from Greek , , 'drawn-out' + , , 'face', because most of its skull was in front of its eyes) is a genus of extinct, amphibious temnospondyls. It contains the type species '''', the fossils of which are found mainly in early Permian deposits of the Texas Red Beds, and Eryops grandis from New Mexico. Fossils have also been found in late Carboniferous rocks from New Mexico and early Permian deposits of Oklahoma, Utah, the Pittsburgh tri-state region, and Prince Edward Island. Several complete skeletons of Eryops'' have been found in lower Permian rocks, but skull bones and teeth are its

Eryopidae are an extinct family of medium to large sized amphibious temnospondyls that lived from the latest Carboniferous (Pennsylvanian) to the early Permian period and inhabited North America and Europe. They were apex predators in the stream and lake habitats they inhabited. Their life cycle (exemplified by Onchiodon) consist of a small larvae that grows into a heavily ossified adult. This group are unusual in their variability in their morphology and development.

Clamorosaurus is an extinct genus of temnospondyl amphibian. Fossils of Clamorosaurus have been found in the Inta Formation (Vorkuta series) in Russia. They are dated to about 272.5 million years ago, which was during the Ufimian interval of the Permian.

Stenokranio (from the Greek στενός [stenos] for narrow and κρανίο [kranio] for skull) is a genus of eryopid temnospondyl from the Permo-Carboniferous Remigiusberg Formation of Germany. It is represented by the type species, Stenokranio boldi, which was named for two specimens collected from the Remigiusberg quarry near Kusel, Saar–Nahe Basin, southwest Germany.
