Urocordylidae
The Urocordylidae are an extinct family (biology), family of nectridean lepospondyl amphibians. Urocordylids lived during the Late Carboniferous and Early Permian in what is now Europe and North America and are characterized by their very long, paddle-like tails. In life, they were probably newt-like and aquatic. Fossils have been found from Ireland, France, and the eastern United States. The family was named by English naturalist Richard Lydekker in 1889 and includes the well-known genera ''Urocordylus'' and ''Sauropleura'', as well as several others based on less-complete material. The family Urocordylidae is divided into two subfamilies, the Urocordylinae and the Sauropleurinae. The two groups are distinguished by the shapes of their skulls; urocordylines have short, blunt skulls, and sauropleurines have longer, pointed skulls. Description Urocordylids are distinguished by their elongated tails. Each tail vertebra has an upper crest of bone called a neural arch and a lower cr ...

Nectridea
Nectridea is the name of an extinct order of lepospondyl tetrapods from the Carboniferous and Permian periods, including animals such as ''Diplocaulus''. In appearance, they would have resembled modern newts or aquatic salamanders, although they are not close relatives of modern amphibians. They were characterized by long, flattened tails to aid in swimming, as well as numerous features of the vertebrae. Description Nectrideans are a diverse group of tetrapods, including the aquatic Urocordylidae, the presumably terrestrial Scincosauridae, and the bizarre horned members of Diplocaulidae (also known as Keraterpetonidae), which includes the "boomerang-headed" ''Diplocaulus'', one of the most famous genera of prehistoric amphibians (in the traditional sense of the word). By the time the earliest known nectrideans appeared in the Late Carboniferous fossil record, they had already diversified into these families, indicating that basal nectrideans are unknown.

Diplocaulid
The Diplocaulidae ("double cauls") is an extinct family of lepospondyl amphibians that arose during the Late Carboniferous and died out in the Late Permian. They are distinguished from other amphibians, extinct and extant, by the presence of strange, horn-like protrusions jutting out from the rear of their skulls; in some genera said protrusions gave their heads an almost boomerang-like outline.

Lepospondyl
Lepospondyli is a diverse taxon of early tetrapods. With the exception of one late-surviving lepospondyl from the Late Permian of Morocco (''Diplocaulus minumus''), lepospondyls lived from the Early Carboniferous ( Mississippian) to the Early Permian and were geographically restricted to what is now Europe and North America. Five major groups of lepospondyls are known: Adelospondyli; Aïstopoda; Lysorophia; Microsauria; and Nectridea. Lepospondyls have a diverse range of body forms and include species with newt-like, eel- or snake-like, and lizard-like forms. Various species were aquatic, semiaquatic, or terrestrial. None were large (the biggest genus, the diplocaulid ''Diplocaulus'', reached a meter in length, but most were much smaller), and they are assumed to have lived in specialized ecological niches not taken by the more numerous temnospondyl amphibians that coexisted with them in the Paleozoic. Lepospondyli was named in 1888 by Karl Alfred von Zittel, who coined the name t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Batropetes Fritschi
''Batropetes'' is an extinct genus of brachystelechid recumbirostran "microsaur". ''Batropetes'' lived during the Sakmarian stage of the Early Permian. Fossils attributable to the type species ''B. fritschi'' have been collected from the town of Freital in Saxony, Germany, near the city of Dresden. Additional material has been found from the Saar-Nahe Basin in southwestern Germany and has been assigned to three additional species: ''B. niederkirchensis'', ''B. palatinus'', and ''B. appelensis''. Description ''Batropetes'' is small and short-bodied for a microsaur. Its average total body length was about . The orbits are large and the skull is short. ''Batropetes'' possesses scales on its underside that are similar to those of reptiles. ''Batropetes'' is distinguished from ''Carrolla'', another brachystelechid microsaur, by the presence of three cusps on the premaxillary and anterior dentary teeth. In ''Carrolla'', there are only two cusps. Additional diagnostic features see ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
