Eryopidae
Eryopidae were a group of medium to large amphibious temnospondyli, temnospondyls, known from North America and Europe. They are defined as all Eryopoidea, 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.

Actinodon
''Actinodon'' is an extinct genus of eryopoidean temnospondyl within the family (biology), family Eryopidae. History of study ''Actinodon'' was named in 1866 by French paleontologist Jean Albert Gaudry based on a holotype skull that was collected by Charles Frossard near Meuse, France, Muse in the Autun Basin (Cisuralian, early Permian) of France. The status and relationship of the taxon was long problematic because the holotype was thought to be lost, until it was rediscovered in the collections of the National Museum of Natural History, France, Museum d'Histoire Naturelle in 1996. In the intervening 130 years, a variety of specimens were described by other workers, some of which were attributed to other species or only to the genus level. Werneburg & Steyer (1999) were the most recent to redescribe material of this taxon, and they referred it to the Eryopoidea, eryopoid ''Onchiodon'' as a valid species, while Schoch & Milner (2000) argued that it might be a species of the St ...

Temnospondyli
Temnospondyli (from Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent. A few species continued into the Jurassic and Early Cretaceous periods, but all had gone extinct by the Late Cretaceous. During about 210 million years of evolutionary history, they adapted to a wide range of habitats, including freshwater, terrestrial, and even coastal marine environments. Their life history is well understood, with fossils known from the larval stage, metamorphosis and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted to life on land. Although temnospondyls are amph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stenokranio
''Stenokranio'' (from the Greek στενός tenosfor narrow and κρανίο raniofor 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. Description The type and only species, ''S. boldi'', is diagnosed by three autapomorphic features of the skull that differentiate it from all other eryopids: (1) the relatively narrow posterior skull table, therefore nearly parallel lateral margins of the skull; (2) the short postparietals and tabulars; and (3) the wide ectopterygoid. The two known skulls measure (holotype) and (paratype) and are thought to represent adult, though not fully mature, individuals. The holotype is represented by a nearly complete skull and mandibles, while the paratype is represented by a partial skull, mandible, and ante ...

Eryopoidea
Eryopoidea is a clade of Pennsylvanian (geology), late Carboniferous and Permian temnospondyli, temnospondyl amphibians, known from North America and Europe. Carroll (1998) includes no fewer than ten families, but Yates and Warren (2000) replaced this with a Cladistics, cladistic approach that includes three closely-related families, the Eryopidae, Parioxyidae and Zatrachydidae. They define the Eryopoidea as all members of Euskelia in which the choana are relatively rounded and the iliac blade is vertical. A similar definition (without specifically naming Euskelia) is provided by Laurin and Steyer (2000).

Clamorosaurus
''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. ''Clamorosaurus'' had a skull length of about 23 cm. (9 inches). The vacuities between the pterygoid bones of ''Clamorosaurus'' were rounded at the front. The external nares were large.

Eryops
''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 single species , the fossils of which are found mainly in early Permian (about 295 million years ago) rocks of the Texas Red Beds, located in Archer County, Texas. Fossils have also been found in late Carboniferous period rocks from New Mexico. Several complete skeletons of ''Eryops'' have been found in lower Permian rocks, but skull bones and teeth are its most common fossils. Description ''Eryops'' averaged a little over long and could grow up to , making them among the largest land animals of their time. Adults weighed between . The skull was proportionately large, being broad and flat and reaching lengths of . It had an enormous mouth with many curved teeth, like those of frogs. Its teeth had enamel with a folded pattern, leading to its early classification as a " labyrinthodont" ("maze toothed") ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
