Reiszerpeton Renascentis
''Reiszerpeton'' is an extinct genus of dissorophid temnospondyl known from the Early Permian Archer City Formation of Texas. It is known solely from the holotype, MCZ 1911, a complete skull. This specimen was originally referred to the amphibamiform '' Tersomius texensis''. A reappraisal of the holotype of ''T. texensis'' and a number of other referred specimens by Maddin et al. (2013) noted a number of differences from both ''T. texensis'' and amphibamiforms more broadly that suggested affinities with the Dissorophidae. This was confirmed by a phylogenetic analysis, which placed it as the sister taxon to the Eucacopinae (''Cacops'' + ''Zygosaurus'' + ''Kamacops''). ''Reiszerpeton'' is known only from the type species, ''R. renascentis'', which was named for Canadian paleontologist Robert Reisz Robert Rafael Reisz is a Canadian paleontologist and specialist in the study of early amniote and tetrapod evolution.

Conjunctio
''Conjunctio'' is an extinct genus of dissorophid temnospondyl amphibian from the early Permian of New Mexico. The type species, ''Conjunctio multidens'', was named by paleontologist Robert L.

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 ...

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] |
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] |
Phonerpeton
''Phonerpeton'' is an extinct genus of dissorophoid temnospondyl within the family Trematopidae that is known from the early Permian The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. 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). Material referred to the taxon comes from the Archer City, Nocona, and Petrolia Formations and was collected between 1934 and 1952 by parties led by A.S. Romer, L.I. Price, and ...

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 ...

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] |
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.
