Zatrachys
''Zatrachys'' is an extinct genus of large and flat-headed zatracheidid temnospondyl from the early Permian of North America. History of study ''Zatrachys'' was named by American paleontologist Edward Drinker Cope in 1878 for the type species, ''Z. serratus'', based on a partial skull from the early Permian of Texas. Additional material has been reported from the early Permian of New Mexico and Oklahoma. Urban et al. (2007) reported material attributed to ''Z. serratus'' from the late Carboniferous and the early Permian of West Virginia. This is the only record of ''Zatrachys'' in the Carboniferous. ''Zatrachys microphthalmus'' is now placed within '' Dasyceps''. Anatomy Like all zatracheidids, ''Zatrachys'' is easily recognized by the presence of a large opening in the snout, the internarial fontanelle or fenestra. Of the three genera of zatracheidids, that of ''Zatrachys'' is the largest, extending as far back as to fully divide the nasals and to partially divide the fro ...

Zatrachydidae
Zatracheidae (sometimes mistakenly spelled Zatrachydidae or Zatrachysdidae) is a family of Late Carboniferous and Early Permian temnospondyl amphibians known from North America and Europe. Zatracheidids are distinguished by lateral (sideways) bony protuberances of the quadratojugal bone of the skull, and a large opening in the snout called the internarial fontanelle (sometimes the internarial fenestra) that is bordered by enlarged premaxillae. The skull is flattened, with small orbits or eye sockets set far back. The opening in the snout may have housed a gland for producing a sticky substance so that prey would adhere to the tongue. If so, this indicates that these animals spent a large part of their time on land. History of study There are three genera of zatracheidids: '' Acanthostomatops'' Kuhn, 1961; '' Dasyceps'' Huxley 1859; and '' Zatrachys'' Cope, 1878. Only ''Dascyeps'' is represented by a species in addition to the type species. The name Zatracheidae was first coin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasyceps
''Dasyceps'' is an extinct genus of zatracheidid temnospondyl from the early Permian of England. History of study ''Dasyceps'' was originally named in 1850 for the type species, ''D. bucklandi'', which honors English paleontologist William Buckland, but under the now defunct genus "''Labyrinthodon''," which is now regarded as a junior synonym of the Triassic capitosaur ''Mastodonsaurus''. The new genus name for the species was created by Thomas Huxley in 1859. A detailed description of the taxon was given in German by the German paleontologist Friedrich von Huene Friedrich von Huene, born Friedrich Richard von Hoinigen, (March 22, 1875 – April 4, 1969) was a German paleontologist who renamed more dinosaurs in the early 20th century than anyone else in Europe. He also made key contributions about v ... in 1910. The most recent description is that of Paton (1975).

Temnospondyli
Temnospondyli (from Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian, and Triassic periods. A few species continued into the Jurassic and Cretaceous periods. Fossils have been found on every continent. During about 210 million years of evolutionary history, they adapted to a wide range of habitats, including freshwater, terrestrial, and even coastal marine environments. Their life history is well understood, with fossils known from the larval stage, metamorphosis, and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted to life on land. Although temnospondyls are considered amphibians, many had characteristics, such as scales and armour-like bon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Autapomorphy
In phylogenetics, an autapomorphy is a distinctive feature, known as a derived trait, that is unique to a given taxon. That is, it is found only in one taxon, but not found in any others or outgroup taxa, not even those most closely related to the focal taxon (which may be a species, family or in general any clade). It can therefore be considered an apomorphy in relation to a single taxon. The word ''autapomorphy'', first introduced in 1950 by German entomologist Willi Hennig, is derived from the Greek words αὐτός, ''autos'' "self"; ἀπό, ''apo'' "away from"; and μορφή, ''morphḗ'' = "shape". Discussion Because autapomorphies are only present in a single taxon, they do not convey information about relationship. Therefore, autapomorphies are not useful to infer phylogenetic relationships. However, autapomorphy, like synapomorphy and plesiomorphy is a relative concept depending on the taxon in question. An autapomorphy at a given level may well be a synapomorphy at ...

Acanthostomatops
''Acanthostomatops'' is an extinct genus of zatracheidid temnospondyl Temnospondyli (from Greek language, Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order (biology), order of small to giant tetrapods—often considered Labyrinthodontia, primitive amphi ... from the Lower Permian Döhlen Basin of Saxony. History of study ''Acanthostomatops'' was originally named as the type species ''Acanthostoma vorax,'' in 1883. However, the genus name ''Acanthostoma'' was previously used for a polychaete worm back in 1813, and the present name was given in 1961. Detailed descriptions of the taxon were given by Steen & Brough (1937), with an emphasis on the ontogeny of the taxon based on the large sample size given by Boy (1989) and Witzmann & Schoch (2006). Werneburg (1998) described a larval specimen of ''A. vorax'', but this was later proven to be a specimen of the micromelerpetid '' Branchierpeton amblystomum''. Anatomy ...

Platyhystrix
''Platyhystrix'' (from el, πλατύς , 'flat' and el, ῠ̔́στρῐξ , 'porcupine') was a temnospondyl amphibian with a distinctive sail along its back, similar to the unrelated synapsids, ''Dimetrodon'' and ''Edaphosaurus''. It lived during the boundary between the latest Carboniferous and earliest Permian periods in Red Beds of Texas and Oklahoma, Texas, about 300 million years ago. Palaeobiology ''Platyhystrix'' may have been preyed upon by larger temnospondyls such as ''Eryops'', or by larger carnivorous reptiles, which were becoming more common and diverse in the drier climate of the Permian. The skull was large and strongly built, with a frog-like face. ''Platyhystrix'' had a compact body, reaching long including the tail, and its short, sturdy legs indicate a mainly terrestrial life. ''Platyhystrix'' appeared rather unusual: the dorsal vertebrae were extraordinarily lengthened, and in life they probably formed a skin-covered sail. This structure was possibly for ...

Cisuralian Temnospondyls Of North America
The Cisuralian is the first series/epoch of the Permian. The Cisuralian was preceded by the Pennsylvanian and followed by the Guadalupian. The Cisuralian Epoch is named after the western slopes of the Ural Mountains in Russia and Kazakhstan and dates between 298.9 ± 0.15 – 272.3 ± 0.5 Mya. The Cisuralian is often synonymous with the informal terms early Permian or lower Permian. It corresponds approximately with the Wolfcampian in southwestern North America. The series saw the appearance of beetles and flies and was a relatively stable warming period of about 21 million years. Name and background The Cisuralian is the first series or epoch of the Permian. The Cisuralian was preceded by the last Pennsylvanian epoch (Gzhelian) and is followed by the Permian Guadalupian Epoch. The name "Cisuralian" was proposed in 1982, and approved by the International Subcommission on Permian Stratigraphy in 1996. The Cisuralian Epoch is named after the western slopes of the Ural Mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
