Trematopid
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 ...

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] |

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] |
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 ...

Actiobates
''Actiobates'' is an extinct genus of trematopid temnospondyl that lived during the Late Carboniferous. It is known from the Garnett Quarry in Kansas. History of study ''Actiobates peabodyi'' was named in 1973 by Theodore Eaton. The genus name derives from the Greek words ' ("shore") and ' ("walker"), referring to the estuarine nature of the Garnett Quarry deposits, and the specific name is for the American paleontologist Frank Peabody. The taxon is based on a single specimen represented by a partial skull and associated postcranial skeleton that is currently deposited at the University of Kansas Natural History Museum. Anatomy The holotype of ''A. peabodyi'' is dorsoventrally compressed, obscuring many details of the anatomy. Schoch & Milner (2014) listed only one diagnostic feature for the taxon, a quadratojugal excluded from the smooth ventral border of the otic notch. Relationships Eaton (1973) originally classified ''Actiobates'' as a dissorophid but only because he cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dissorophidae
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 d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Cacops
''Cacops'' ("ugly look" for its strange appearance), is a genus of dissorophid temnospondyls from the Kungurian stage of the early Permian of the United States. ''Cacops'' is one of the few olsoniforms (dissorophids and the larger trematopids) whose ontogeny is known. ''Cacops'' fossils were almost exclusively known from the Cacops Bone Bed of the Lower Permian Arroyo Formation of Texas for much of the 20th century. New material collected from the Dolese Brothers Quarry, near Richards Spur, Oklahoma in the past few decades has been recovered, painting a clearer picture of what the animal looked and acted like. History of discovery ''Cacops aspidephorus'' is the most famous dissorophid, in part due to a majority of its skeleton having been known for over a century. Over 50 specimens have been found in the ''Cacops'' Bone Bed in Baylor County, Texas, which is now flooded by the dammed Lake Kemp. However, many of the specimens are covered in calcite, which penetrates the bone tis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnerpeton
''Limnerpeton'' is an extinct genus of dissorophoidean euskelian temnospondyl within the family Amphibamidae. Taxonomy ''Limnerpeton'' is currently restricted to the type species ''L. modestum'', which is dubious but represents an amphibamid. The nominal species ''"Limnerpeton" laticeps'' was later assigned to the trematopid '' Mordex'' but has been placed in a separate trematopid genus '' Mattauschia'' following Milner (2018). The nominal species ''L." macrolepis'' was synonymized with ''laticeps'' by Milner and Sequeira (2003) and Milner (2018). ''"Limnerpeton" elegans'' was reassigned to Micromelerpetontidae and renamed ''Limnogyrinus'' by Milner (1986). ''"Limnerpeton" caducus'' is a junior synonym of '' Oestocephalus'', while ''"Limnerpeton" obtusatum'' was synonymized with '' Microbrachis'' by Carroll and Gaskill (1978).Carroll, R.L. and Gaskill, P. 1978.
