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 confusingly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gephyrostegus Bohemicus
''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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetrapod
Tetrapods (; ) are four-limbed vertebrate animals constituting the superclass Tetrapoda (). It includes extant and extinct amphibians, sauropsids ( reptiles, including dinosaurs and therefore birds) and synapsids (pelycosaurs, extinct therapsids and all extant mammals). Tetrapods evolved from a clade of primitive semiaquatic animals known as the Tetrapodomorpha which, in turn, evolved from ancient lobe-finned fish (sarcopterygians) around 390 million years ago in the Middle Devonian period; their forms were transitional between lobe-finned fishes and true four-limbed tetrapods. Limbed vertebrates (tetrapods in the broad sense of the word) are first known from Middle Devonian trackways, and body fossils became common near the end of the Late Devonian but these were all aquatic. The first crown-tetrapods (last common ancestors of extant tetrapods capable of terrestrial locomotion) appeared by the very early Carboniferous, 350 million years ago.

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bruktererpeton
''Bruktererpeton'' is an extinct genus of gephyrostegid reptiliomorph known from the Late Carboniferous of the Rhein-Ruhr-District, western Germany. It was first described and named by Jürgen A. Boy and Klaus Bandel in 1973 and the type species is ''Bruktererpeton fiebigi''. Recent phylogenetic analyses confirmed that ''Bruktererpeton'' is a sister taxon of the better known genus ''Gephyrostegus ''Gephyrostegus'' is an extinct genus of gephyrostegid reptiliomorph amphibian.

Eusauropleura
''Eusauropleura'' is an extinct genus of gephyrostegid reptiliomorph from the Pennsylvanian (Late Carboniferous) of Linton, Ohio. The type species and only species, ''Eusauropleura digitata'', was first described by American paleontologist Edward Drinker Cope in 1868 as ''Sauropleura digitata''. In 1930, paleontologist Alfred Romer placed the species in the new genus ''Eusauropleura''. Romer considered ''S. digitata'' to be a reptile or a more primitive relative of reptiles, making it only distantly related to ''Sauropleura'', which is a lepospondyl amphibian. ''Eusauropleura'' is known from ribs and limb bones, but no skull is known. The holotype fossil is preserved in ventral view with a dense coating of small scales covering its underside. The arms and legs are nearly complete. It is similar in appearance to ''Gephyrostegus'' from the Czech Republic, with closely matching body proportions. Compared to ''Gephyrostegus'', ''Eusauropleura'' has a more weakly ossified Ossi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czech Republic
The Czech Republic, or simply Czechia, is a landlocked country in Central Europe. Historically known as Bohemia, it is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec. The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial State of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg monarchy. The Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Empire in 1806, the Cro ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states.
