Eogyrinus
''Pholiderpeton'' (from el, φολῐ́δος , 'horny scale' and el, ἑρπετόν , 'creeping thing') is an extinct genus of embolomere amphibian which lived in the Late Carboniferous period ( Bashkirian) of England. The genus was first named by Thomas Henry Huxley in 1869 to include the species ''P. scutigerum'', based on the disarticulated front half of a skeleton discovered near Bradford, Yorkshire. Associated fossil wood suggests that this specimen died inside a ''Lepidodendron'' tree trunk. In 1987, Jennifer A. Clack suggested that a different embolomere, ''Eogyrinus attheyi'' from Newsham, Northumberland, belonged to the same genus as ''Pholiderpeton''. She subsumed the genus ''Eogyrinus'' into ''Pholiderpeton'' and created the new combination ''P. attheyi''. The anatomy of ''"Eogyrinus"'' ''attheyi'' has been described in detail by A.L. Panchen. Some phylogenetic analyses, such as those by Marcello Ruta & Michael Coates (2007) and David Marjanović & Michel Lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neopteroplax
''Neopteroplax'' is an extinct genus of eogyrinid embolomere closely related to European genera such as ''Eogyrinus'' and '' Pteroplax''. Members of this genus were among the largest embolomeres (and Carboniferous tetrapods in general) in North America. ''Neopteroplax'' is primarily known from a large (~40 cm) skull found in Ohio, although fragmentary embolomere fossils from Texas and New Mexico have also been tentatively referred to the genus. Despite its similarities to specific European embolomeres, it can be distinguished from them due to a small number of skull and jaw features, most notably a lower surangular at the upper rear portion of the lower jaw. Discovery The type species, ''Neopteroplax conemaughensis'', is known from a large skull found in Late Carboniferous shale during railroad renovations in Bloomingdale, Ohio. Although damaged by excavators, most of the left side of the skull can be reconstructed based on surviving fragments. The only other ''Neopteroplax' ...

Palaeoherpeton
''Palaeoherpeton'' is an extinct genus of eogyrinid embolomere which lived in the Pennsylvanian (late Carboniferous) of Scotland. It is primarily known from a series of relatively small but well-preserved skulls. Some of these have among the best braincase and middle ear material known in embolomeres. Originally given the species name ''Palaeogyrinus decorus'', this was later corrected to ''Palaeoherpeton decorum'' when it was determined that '' Palaeogyrinus'' was a name preoccupied by a genus of beetles Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 describ ....

Pteroplax
''Pteroplax'' is an extinct genus of Embolomeri, embolomerous Anthracosauria, anthracosaur. Only one species (''P. cornutus'' Hancock & Atthey, 1868) has been described; the skull table noted is the lectotype of this species. ''Pteroplax'' dates from the Pennsylvanian (geology), late Carboniferous Period, about 315 million years ago. It is known with certainty only from Newsham in Blyth, Northumberland, England. At that site, it shared a coal-swamp lake habitat with the larger embolomere, "''Eogyrinus''" (whose name is a junior synonym of ''Pholiderpeton'' Huxley, 1869). ''Pteroplax'' probably grew up to about in length and was largely aquatic, feeding upon fish and smaller tetrapods. It likely had a long, eel-like body, with short limbs and a long tail. Although ''Pteroplax cornutus'' is known with total certainty only from the type specimen (an isolated skull table), Boyd (1978) described both cranial and postcranial elements from Newsham as probably belonging to this species.

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. The specific aquatic ancestors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carboniferous Vertebrates
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' 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 and 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 and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lineages ...

Embolomeres
Embolomeri is an order of tetrapods or stem-tetrapods, possibly members of Reptiliomorpha. Embolomeres first evolved in the Early Carboniferous ( Mississippian) Period and were the largest and most successful predatory tetrapods of the Late Carboniferous ( Pennsylvanian) Period. They were specialized semiaquatic predators with long bodies for eel-like undulatory swimming. Embolomeres are characterized by their vertebral centra, which are formed by two cylindrical segments, the pleurocentrum at the rear and intercentrum at the front. These segments are equal in size. Most other tetrapods have pleurocentra and intercentra which are drastically different in size and shape. Embolomeres were among the earliest large carnivorous tetrapods, with members such as the crocodilian-like '' Proterogyrinus'' appearing in the Visean stage of the Carboniferous. They declined in diversity during the Permian period, though at least one representative ('' Archeria)'' was common in the Early Permian ...

Geologic Period
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define gl ...
