Diplocaulids
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.

Diplocaulus Minimus
''Diplocaulus'' (meaning "double caul") is an extinct genus of lepospondyl amphibians which lived from the Late Carboniferous to the Late Permian of North America and Africa. ''Diplocaulus'' is by far the largest and best-known of the lepospondyls, characterized by a distinctive boomerang-shaped skull. Remains attributed to ''Diplocaulus'' have been found from the Late Permian of Morocco and represent the youngest-known occurrence of a lepospondyl. Description ''Diplocaulus'' had a stocky, salamander-like body, but was relatively large, reaching up to in length. Although a complete tail is unknown for the genus, a nearly complete articulated skeleton described in 1917 preserved a row of tail vertebrae near the head. This was construed as circumstantial evidence for a long, thin tail capable of reaching the head if the animal was curled up. Most studies since this discovery have argued that anguiliform (eel-like) tail movement was the main force of locomotion utilized by ''Di ...

Diploceraspis
''Diploceraspis'' is a genus of lepospondyl amphibian. It lived in North America during the Permian period. It closely resembles its relative, ''Diplocaulus''. It generally sports the same features as ''Diplocaulus'', though it was smaller, measuring over 46 cm. Beerbower originally recognised two species, ''D.burkei'' and ''D.conemaughensis'', but they are no longer regarded as being distinct from one another as their size ranges were found to overlap. Other species include ''D. meritae'' from Nebraska and an indeterminate species from Oklahoma. ''Diplocaulus minimus'' of Late Permian Morocco Morocco (),, ) officially the Kingdom of Morocco, is the westernmost country in the Maghreb region of North Africa. It overlooks the Mediterranean Sea to the north and the Atlantic Ocean to the west, and has land borders with Algeria t ... may be of this genus.

Batrachiderpeton
''Batrachiderpeton'' is an extinct genus of nectridean lepospondyl within the family Diplocaulidae; it was a basal member of the family. The type species is ''B. reticulatum'' and was found in a coal field in Northumberland, England at a locality that also yields the remains of '' Anthracosaurus russelli''.Hancock, A. & Athey, T. (1869). On a new labyrinthodont from the Northumberland coal field, and on the occurrence in the same locality of '' Anthracosaurus russelli''.

Diceratosaurus
''Diceratosaurus'' is an extinct genus of nectridean lepospondyl within the family Keraterpetontidae. Fossils of ''Diceratosaurus'' were first described by Edward Drinker Cope in 1874. The species ''D. brevirostris'' is well known from Jefferson County, Ohio, with approximately 50 specimens having been collected from the Ohio Diamond Coal Mine. The mine was situated in the village of Linton, which became obscure soon after operations were completed and the mine closed in 1921.

Keraterpeton
''Keraterpeton'' is an extinct genus of lepospondyl amphibian, previously included within the monotypic Keraterpedontidae family, from the Carboniferous period of Europe (Czech Republic, England and Ireland)Brownrigg, W. B. (1865). Notes on part of the Leinster Coalfield, with a record of some fossils found therein. ''Dublin Quarterly Journal of Science'' 6, 195–196.Google Scholar and North America (United States); it is the oldest known member of the family Diplocaulidae. The type species is ''Keraterpeton galvani'', named in 1866 as ''Ceraterpeton'' by Robert Etheridge and later amended to ''Keraterpeton'' in 1868 by Thomas Henry Huxley and Edward Percival Wright; three years earlier (in November 1865), they were authorised by William Bookey Brownrigg to describe some fossil vertebrates in his collection, and among them was NHMING F 14735, the holotype of ''Keraterpeton galvani'', which was discovered in the Jarrow Colliery in County Kilkenny, Ireland.

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 ...

Scincosaurus
''Scincosaurus'' is an extinct genus of nectridean lepospondyl within the family Scincosauridae. History ''Scincosaurus crassus'' was first described by Bohemian paleontologist Antonín Frič in volume 1875 of "''Sitzungsberichte der königlichen Böhmischen Gesellschaft der Wissenschaften in Prague''", which at that time was the premiere scientific journal of Bohemia (the modern day Czech Republic). Frič's contribution to this volume was a list of Carboniferous animals he and his associates recently discovered at coal gas mines near the localities of Nýřany and Kounová. His list included short preliminary descriptions for many new genera and species of tetrapods, including '' Microbrachis, Branchiosaurus, Hyloplesion'' (at that time called ''Stelliosaurus''), and ''Sparodus.'' ''Scincosaurus crassus'' was among the new tetrapods from Nýřany, and its short description (erroneously) considered it a robust lacertilian ( lizard), possibly related to ''Sparodus''. A m ...
