Ecolsonia
''Ecolsonia'' is an extinct genus of trematopid temnospondyl. Its phylogenetic position within Olsoniformes has been historically debated, but it is presently considered to be a trematopid. History of study The holotype of ''Ecolsonia'' is a partial skull that was collected in 1963 from the VanderHoof quarry in the Early Permian Cutler Formation of New Mexico. The specimen was originally reposited at the now defunct University of California, Los Angeles Vertebrate Paleontology collections. The genus name is for the American paleontologist Everett C. Olson, and the species name is for the geologic provenance. A number of more complete specimens from the Morfin quarry in the Cutler Formation were discovered in 1983 and described by Berman et al. (1985), including a complete skull and large amounts of postcranial material. These specimens are currently reposited at the Carnegie Museum of Natural History. Anatomy Schoch & Milner (2014) listed seven features in the diagnosis of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trematopidae
Trematopidae is a family of dissorophoid temnospondyl spanning the late Carboniferous to the early Permian. Together with Dissorophidae, the family forms Olsoniformes, a clade comprising the medium-large terrestrial dissorophoids. Trematopids are known from numerous localities in North America, primarily in New Mexico, Oklahoma, and Texas, and from the Bromacker quarry in Germany. History of study The clade Trematopidae was first proposed by American paleontologist S.W. Williston in 1910, although it was named as "Trematopsidae" following the historical (but inaccurate) derivation from the genus "''Trematops''" (now synonymized with ''Acheloma''). British paleontologist D.M.S. Watson proposed a related clade in 1919, Achelomidae, for ''Acheloma'', based on perceived differences separating the taxa; this is now considered a junior synonym of Trematopidae following guidelines of historical precedent. 19th century history In 1882, American paleontologist Edward Drinker Cope na ...

Anconastes
''Anconastes'' is an extinct genus of dissorophoid temnospondyl within the family Trematopidae. It is known from two specimens from the Late Carboniferous Cutler Formation of north-central New Mexico in the southwestern United States. The genus name derives from two Greek roots, ''ankos'' ("mountain glen or valley") and ''nastes'' ("inhabitant"), which refers to the type locality of El Cobre Canyon where the specimens were found. The specific name is derived from the Latin word ''vesperus'' ("western"). The more complete specimen, the holotype, is a partial skull with articulated mandibles and a substantial amount of the postcranial skeleton. The less complete specimen, the paratype, consists only of the right margin of the skull with an articulated mandible. Anatomy When originally described, only three other trematopid taxa were recognized: '' Acheloma, Actiobates'', and "'' Trematops''" (now a synonym of ''Acheloma''); '' Ecolsonia'', which is now considered a trematopid by ...

Dissorophids
Dissorophidae is an extinct family of medium-sized, temnospondyl amphibians that flourished during the late Carboniferous and early Permian periods. The clade is known almost exclusively from North America. History of study Dissorophidae is a diverse clade that was named in 1902 by George A. Boulenger. Junior synonyms include Otocoelidae, Stegopidae, and Aspidosauridae. Early in the study of dissorophoids when the relationships of different taxa were not well-resolved and most taxa had not been described, Dissorophidae sometimes came to include taxa that are now not regarded as dissorophids and may have excluded earlier described taxa that are now regarded as dissorophids. Amphibamiforms were widely regarded as small-bodied dissorophids, and at one point, Dissorophidae was also suggested to also include Trematopidae. 19th century In 1895, American paleontologist Edward Drinker Cope named ''Dissorophus'' from the early Permian of Texas. This was the first dissorophid to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 cha ...

Dissorophus
''Dissorophus'' (DI-soh-ROH-fus) (meaning "double roof" for two layers of armor) is an extinct genus of temnospondyl amphibian that lived during the Early Permian Period about 273 million years ago. Its fossils have been found in Texas and in Oklahoma in North America. Its heavy armor and robust build indicate ''Dissorophus'' was active on land, similar to other members of the clade Dissorophidae that are known from the Late Carboniferous to the Early Permian periods. ''Dissorphus'' is distinguished by its small body size, disproportionately large head and short trunk. The American paleontologist Edward Drinker Cope first briefly described ''Dissorophus'' in 1895,Cope. E.D. 1895. A batrachian armadillo. ''American Naturalist'' 29:99/ref> likely deriving the genus name from Ancient Greek δισσός/dissos "double" and ὀροφή/orophe "roof" to refer to the double layer of armor formed by horizontal "spinous branches" at the top of the neural spines of the vertebrae that "tou ...

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 ...

Olsoniformes
Olsoniformes is a clade of dissorophoid temnospondyls. It includes the families Dissorophidae and Trematopidae. Most members of the clade were highly adapted to a terrestrial lifestyle. The clade was named in 2008 and is defined as the least inclusive clade containing ''Dissorophus multicinctus'' (a dissorophid) and ''Acheloma cumminsi'' (a trematopid) but not ''Amphibamus grandiceps, Micromelerpeton credneri,'' and ''Apateon pedestris''. Olsoniforms share various features such as a stout and low ilium and a thin cultriform process. Trematopids are known from the Late Carboniferous and the Early Permian of Europe and across much of North America, while dissorophids are primarily found in Early Permian deposits in the central United States The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cisuralian
The Cisuralian is the first Series (stratigraphy), series/Epoch (geology), epoch of the Permian. The Cisuralian was preceded by the Pennsylvanian (geology), 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 Fly, 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 Ci ...

Cutler Formation
The Cutler Formation or Cutler Group is a rock unit that is exposed across the U.S. states of Arizona, northwest New Mexico, southeast Utah and southwest Colorado. It was laid down in the Early Permian during the Wolfcampian epoch. Description At its type area north of Ouray, Colorado, the Cutler Formation consists of over of bright red sandstone, siltstone, and conglomerate beds alternating with reddish mudstone or clay-rich limestone. Further west, the unit shows great lithological diversity, and can be divided into easily recognizable mappable subunits. Here the Cutler is raised from formation to group rank and its subunits are themselves designated as formations. The unit in its type area remains at formation rank and is often described as the "undifferentiated Cutler". The formation overlies the Hermosa Group and is in turn overlain by either the Dolores Formation (near its type area) or the Moenkopi Formation (further west). It is laterally equivalent to the Abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
