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 ...

Nectridean
Nectridea is 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 Lissamphibia, 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.

Sauropleurinae
Sauropleurinae is an extinct subfamily of nectridean tetrapodomorphs. Along with the subfamily Urocordylinae, Sauropleurinae is part of the family Urocordylidae. Like other urocordylids, sauropleurines have long, flattened tails and superficially resemble aquatic newts. They differ from urocordylines in having narrow, pointed skulls. Sauropleurinae includes the genera ''Sauropleura'', ''Crossotelos'', '' Lepterpeton'', and '' Montcellia'', which lived during the Late Carboniferous and Early Permian 01 or 01 may refer to: * The year 2001, or any year ending with 01 * The month of January * 1 (number) Music * '01 (Richard Müller album), ''01'' (Richard Müller album), 2001 * 01 (Urban Zakapa album), ''01'' (Urban Zakapa album), 2011 * ''01011 ... in what is now North America and Europe.

Urocordylinae
Urocordylinae is an extinct subfamily of nectridean tetrapodomorphs that includes several small newt-like species with short skulls and elongated, flattened tails. Urocordylinae belongs to the family Urocordylidae, which also includes the subfamily Sauropleurinae.

Lepospondyli
Lepospondyli is a diverse clade of early tetrapods. With the exception of one late-surviving lepospondyl from the Late Permian of Morocco ('' Diplocaulus minimus''), lepospondyls lived from the Visean stage of the Early Carboniferous 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 coi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplocaulid
The Diplocaulidae ("double cauls") is an extinct family of "nectridean" tetrapodomorphs that arose during the Late Carboniferous and died out in the Late Permian. They are distinguished 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.

Odonterpeton Triangulare
''Odonterpeton'' is an extinct genus of "microsaur" (small Reptile, reptiles or reptile-like Amphibian, amphibians) from the Pennsylvanian (geology), Late Carboniferous of Ohio, containing the lone species ''Odonterpeton triangulare''. It is known from a single partial skeleton preserving the skull, forelimbs, and the front part of the torso. The specimen was found in the abandoned Diamond Coal Mine of Linton, Ohio, a fossiliferous coal deposit dated to the late Moscovian (Carboniferous), Moscovian stage (Westphalian D), about 310 million years ago. ''Odonterpeton'' was very small even among microsaurs, and its skeletal anatomy has been compared to aquatic Salamander, salamanders such as amphiuma. Its habitat was a tropical river and delta environment bustling with fish, amphibians, and rare early reptiles. The three-fingered forelimbs are tiny, and hindlimb evidence is unclear. ''Odonterpeton'' is the sister taxon to ''Joermungandr bolti'' (a scaly four-limbed microsaur from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
