Trematopids
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 name ...

Acheloma
''Acheloma'' (also known as ''Trematops milleri'') is an extinct genus of temnospondyl that lived during the Early Permian. The type species is ''A. cumminsi''. History of study ''Acheloma'' was named by Edward Drinker Cope in 1882 based on a partial skull with associated postcranial elements from the Arroyo Formation of Texas; the specimen is currently reposited at the American Museum of Natural History in New York. Subsequent discoveries of large trematopids from the Arroyo Formation were named as different species of ''Trematops'' (''T. milleri, T. willistoni''), but these have since been synonymized with ''Acheloma cumminsi''. ''Trematops stonei'' from the Washington Formation of Ohio and ''Trematops thomasi'' from Oklahoma have also been synonymized with ''A. cumminsi''. A second species of ''Acheloma'' was described by Polley & Reisz (2011) from the Richards Spur locality in Oklahoma. Anatomy Schoch & Milner (2014) provide nine characters in their diagnosis of ''A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tambachia
''Tambachia'' is an extinct genus of dissorophoid temnospondyl within the family Trematopidae. It is known from the Early Permian Tambach Formation (the lowermost unit of the Upper Rotliegend) near the town of Tambach-Dietharz in Thuringia, Germany. ''Tambachia'' is the first trematopid to have been discovered outside the United States. Discovery The holotype specimen of ''Tambachia trogallas'', known as MNG 7722, has been found from an outcrop of the Tambach Formation at the Bromacker locality in the Thuringian Forest of central Germany. It consists of a skull and much of the postcranial skeleton. The only major portion of the skeleton that is missing is the presacral vertebral column. The Bromacker locality is a sandstone quarry that is well known for tetrapod trackways and articulated skeletons of terrestrial and semiterrestrial amphibians and reptiles. MNG 7722 was found in red-bed fluvial deposits consisting of well consolidated mudstones in flat-bedded channel fills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mattauschia
''Mattauschia'' is an extinct genus of trematopid temnospondyls from the Late Carboniferous of the Czech Republic. Taxonomy The type species of ''Mattauschia'', ''M. laticeps'', was named ''Limnerpeton laticeps'' by Fritsch (1881) for a small post-metamorphic specimen from Late Carboniferous coal deposits in the Czech Republic. Milner and Sequeira (2003) synonymized it and the nominal species ''Limnerpeton macrolepis'' with ''Mordex, Mordex calliprepes'', interpreting them as representing growth stages of one trematopid species.Milner, A.R. and Sequeira, S.E.K. 2003. Revision of the amphibian genus Limnerpeton (Temnospondyli) from the Upper Carboniferous of the Czech Republic. Acta Palaeontologica Polonica 48 (1): 123–141. Milner (2018) eventually recognized ''laticeps'' as distinct from the ''M. calliprepes'' holotype, so he erected ''Mattauschia'' for ''laticeps'', which includes the lectotype specimen NMP M470/471 as well as the paralectotype NMP M639 and ''Limnerpeton macrol ...

It is the last ... of Texas. History of study ''Phonerpeton'' was first named by Dilkes (1990), with ''Phonerpeton pricei'' as the only species. The genus name comes from the Greek words '''phonos''' (murderous) and '''herpeton''' (creeper). The holotype of ''P. pricei'' was previously described by Olson (1941) as ''Acheloma pricei''. Dilkes also synonymized this species with ''Acheloma whitei'', which was also described by Olson (1941).

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 ...

Rotaryus
''Rotaryus'' is an extinct genus of Early Permian trematopid dissorophoid temnospondyl known from the Free State of Thuringia of central Germany. Discovery ''Rotaryus'' is known only from the holotype MNG 10182, articulated partial well-preserved skull and both mandibles and a closely associated partial postcranial skeleton. The postcranial skeleton includes several articulated neural arches with ribs, most of the left shoulder girdle, humeri, right radius and ulna, and a femur. It was collected from the uppermost part of the Tambach Formation, dating to the Artinskian stage of the Late Cisuralian Series (or alternatively upper Rotliegend), about 284-279.5 million years ago. It was found in the lowermost formational unit of the Upper Rotliegend Group or Series of the Bromacker Quarry, the middle part of the Thuringian Forest, near the village of Tambach-Dietharz. ''Rotaryus'' is only the second trematopid species to be reported from the Bromacker locality, and outside of Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert R
Robert Lee Rayford (February 3, 1953 – May 15 1969), sometimes identified as Robert R. due to his age, was an American teenager from Missouri who has been suggested to represent the earliest confirmed case of HIV/AIDS in North America based on evidence which was published in 1988 in which the authors claimed that medical evidence indicated that he was "infected with a virus closely related or identical to human immunodeficiency virus type 1." Rayford died of pneumonia, but his other symptoms baffled the doctors who treated him. A study published in 1988 reported the detection of antibodies against HIV. Results of testing for HIV genetic material were reported once at a scientific conference in Australia in 1999; however, the data has never been published in a peer-reviewed medical or scientific journal. Background Robert Rayford was born on February 3, 1953, in St. Louis, Missouri to Constance Rayford (September 12, 1931 – April 3, 2011) and Joseph Benny Bell (March 24, 1 ...
