Gephyrostegus
''Gephyrostegus'' is an extinct genus of gephyrostegid reptiliomorph amphibian. It was a small animal, 22 cm in total length, of generally lizard-like build and presumably habit. It had large eyes and a large number of small, pointed teeth, indicating it was an active insectivorous hunter. The remains have been found in Nýřany, Czech Republic, dating from around 310 million years ago (upper Carboniferous). Originally thought to have been a seymouriamorph, the phylogenetic position is uncertain, and now it belongs to the family Gephyrostegidae, together with the genus '' Bruktererpeton''. Several phylogenetic studies indicate that ''Gephyrostegus'' is only distantly related to amniotes, more distantly than diadectomorphs, lepospondyls and seymouriamorphs were. At 22 cm snout-vent length, ''Gephyrostegus'' is one of the smallest (if not ''the'' smallest) advanced reptiliomorphs found. The type species is ''Gephyrostegus bohemicus'', the type of which is the specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplovertebron
''Diplovertebron'' (from el, διπλοῦς , 'double' and la, vertebron, 'vertebra') is an extinct genus of embolomere that lived in the Late Carboniferous period (Moscovian), about 310 million years ago. ''Diplovertebron'' was a medium-sized animal, around 50 cm in length. Members of the genus inhabited European Carboniferous swamps in what is now the Czech Republic. They were closely related to larger swamp-dwelling tetrapods like '' Proterogyrinus'' and ''Anthracosaurus''. However, ''Diplovertebron'' were much smaller than these large, crocodile-like creatures. Known from a single species, ''Diplovertebron punctatum,'' this genus has had a complicated history closely tied to ''Gephyrostegus'', another genus of small, reptile-like amphibians. History ''Diplovertebron'' was one of many tetrapods found in Czech coal swamps by Antonin Frič in the late 19th century. Its remains were an assortment of disarticulated fossils encased in two slabs of coal, which were des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiliomorphs
Reptiliomorpha (meaning reptile-shaped; in PhyloCode known as ''Pan-Amniota'') is a clade containing the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians). It was defined by Michel Laurin (2001) and Vallin and Laurin (2004) as the largest clade that includes ''Homo sapiens'', but not '' Ascaphus truei'' (tailed frog). Laurin and Reisz (2020) defined Pan-Amniota as the largest total clade containing ''Homo sapiens'', but not '' Pipa pipa'', '' Caecilia tentaculata'', and ''Siren lacertina''. The informal variant of the name, "reptiliomorphs", is also occasionally used to refer to stem-amniotes, i.e. a grade of reptile-like tetrapods that are more closely related to amniotes than they are to lissamphibians, but are not amniotes themselves; the name is used in this meaning e.g. by Ruta, Coates and Quicke (2003). An alternative name, "Anthracosauria", is also commonly used for the group, but is confusi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lepospondyli
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solenodonsaurus
''Solenodonsaurus'' ("single-tooth lizard") is an extinct genus of reptiliomorphs that lived in what is now Czech Republic, during the Westphalian stage. Description ''Solenondosaurus'' had snout-vent length with a skull length . ''Solenodonsaurus'' shows a curious mix of characters making it difficult to place phylogenetically. The teeth lack labyrinthodont folding of the enamel, and it skull has a much smaller otic notch than seen in other reptiliomorph amphibians. Yet general build ties it in with the Diadectomorpha.

Carboniferous Tetrapods Of Europe
The Carboniferous ( ) is a Period (geology), geologic period and System (stratigraphy), system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago (Myr, Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin ''wikt:carbo#Latin, carbō'' ("coal") and ''wikt:fero#Latin, ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Stegocephalia, Tetrapods ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coelostegus
''Coelostegus'' is an extinct genus of Late Carboniferous (late Westphalian stage) basal reptile known from Pilsen of Czech Republic. It is known from the holotype ČGH 3027, a partial skeleton of an immature individual. It was collected in the Nýřany site from the Nýřany Member of the Kladno Formation. It was first named by Robert L. Carroll and Donald Baird in 1972 and the type species is ''Coelostegus prothales''. The most recent phylogenic study of primitive reptile relationships found ''Coelostegus'' to be the basalmost known eureptile Eureptilia ("true reptiles") is one of the two major subgroups of the clade Sauropsida, the other one being Parareptilia.

Eureptilia
Eureptilia ("true reptiles") is one of the two major subgroups of the clade Sauropsida, the other one being Parareptilia. Eureptilia includes Diapsida (the clade containing all modern reptiles and birds), as well as a number of primitive Permo- Carboniferous forms previously classified under Anapsida, in the old (no longer recognised) order " Cotylosauria". Eureptilia is characterized by the skull having greatly reduced supraoccipital, tabular, and supratemporal bones that are no longer in contact with the postorbital. Aside from Diapsida, the group notably contains Captorhinidae, a diverse and long lived (Late Carboniferous-Late Permian) clade of initially small carnivores that later evolved into large herbivores. Other primitive eureptiles such as '' Hylonomus'' and " protorothyrids" were all small, superficially lizard-like forms, that were probably insectivorous. One primitive eureptile, the Late Carboniferous "protorothyrid" '' Anthracodromeus,'' is the oldest kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
