Dissorophids
Dissorophidae is an extinct family of medium-sized temnospondyls 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 described as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platyhystrix
''Platyhystrix'' (from Greek: πλατύς ''platús'', 'flat' and Greek: ῠ̔́στρῐξ ''hústrix'', 'porcupine') is an extinct 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 throughout what is now known as the Four Corners, Texas, and Kansas about 300 million years ago. Not much is known about ''Platyhystrix'', with a majority of the fossils found composed of the distinct neural spines, and fractured skull fragments. There is only one species within the genus, ''Platyhystrix rugosus''. Its phylogenetic relationships to other members of the family Dissorophidae have been debated in recent years, due to its unique cranial features, and recent discoveries as to the origins of modern day lissamphibians. Synonyms and alternate spellings include: ''Zatrachys apicalis, Ctenosaurus rugosus, Platyhy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aspidosaurus
''Aspidosaurus'' is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae.

Iratusaurus
''Iratusaurus'' is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae. It was described by Gubin (1980) on the basis of a fragmentary posterior skull. It is estimated to have been comparably large to ''Kamacops'', another Russian dissorophid, but little more can be said about it, and it is rarely mentioned in comparative descriptions and has never been tested in a phylogenetic analysis. Distinguishing features include a large, triangular otic notch and a median crest on the postparietals.

Astreptorhachis
''Astreptorhachis'' is an extinct genus of Late Carboniferous dissorophoid temnospondyl within the family Dissorophidae. It is known only from one species, ''Astreptorhachis ohioensis'', that was collected from Jefferson County, Ohio by the Ohio Geological Survey in 1953 and described by Peter Vaughn in 1971. The holotype and only known specimen consists of a few neural spines and is currently reposited in the Smithsonian Museum of Natural History. The genus name derives from the Greek words ''astreptos'' ("inflexible") and ''rhachis'' ("backbone"). The specimen was recognized as being similar to the dissorophid '' Platyhystrix rugosus'' from the southwestern United States in have greatly elongate neural spines. ''Astreptorhachis'' is differentiated from ''Platyhystrix'' by the fusion of successive neural spines and the extensively developed tubercles that cover the external surfaces. It is speculated that the elongation of the spines served to stiffen the backbone, being advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fayella
''Fayella'' is an extinct genus of dubious temnospondyl from the Early Permian (Guadalupian) of Oklahoma. Taxonomy The holotype of ''Fayella chickashaensis'', FMNH UR 1004, comprises a brain case with part of basicranium, basipterygoid processes, and part of otic complex. It was found in the Chickasha Formation of Oklahoma. Olson (1972) referred a complete specimen (UCLA VP 3066) to ''Fayella'' based on cranial similarities. However, Gee et al. (2018) declared ''Fayella'' a ''nomen dubium'', assigning it to Temnospondyli indeterminate and coining '' Nooxobeia'' for UCLA VP 3066, which is definitely a dissorophid.Bryan M. Gee; Diane Scott; Robert R. Reisz (2018). "Reappraisal of the Permian dissorophid Fayella chickashaensis". Canadian Journal of Earth Sciences. 55 (10): 1103–1114. doi:10.1139/cjes-2018-0053.

Robert L
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' () "fame, glory, honour, praise, renown, godlike" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin.Reaney & Wilson, 1997. ''Dictionary of English Surnames''. Oxford University Press. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe, the name entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including En ...

Broiliellus
''Broiliellus'' is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae. ''Broiliellus'' is most closely related to the genus '' Dissorophus'', and both have been placed in the subfamily Dissorophinae. ''Broiliellus'' is known from five species from the Early Permian: the type species is ''Broiliellus texensis,'' and the other species are ''Broiliellus brevis,'' ''Broiliellus olsoni, Broiliellus arroyoensis,'' and ''Broiliellus reiszi''. An additional species, ''Broiliellus novomexicanus'', which was originally named '' Aspidosaurus novomexicanus'', is now thought to fall outside the genus as a member of the subfamily Eucacopinae. History of study ''Broiliellus'' was first named by American paleontologist S.W. Williston in 1914 based on two nearly complete skulls in articulation with postcranial material from the early Permian of Texas; this species was given the name ''Broiliellus texensis'', the genus name being for the German paleontologist Ferd ...

Samuel Wendell Williston
Samuel Wendell Williston (July 10, 1852 – August 30, 1918) was an American educator, entomologist, and Paleontology, paleontologist who was the first to propose that birds developed flight Origin of birds#Origin of bird flight, cursorially (by running), rather than arboreally (by leaping from tree to tree). He was a specialist on the flies, Diptera. He is remembered for Williston's law, which states that parts in an organism, such as arthropod limbs, become reduced in number and specialized in function through evolutionary history. Early life Williston was born in Boston, Massachusetts to Samuel Williston and Jane A. Williston née Turner. As a young child, Williston's family travelled to Kansas Territory in 1857 under the auspices of the New England Emigrant Aid Company to help fight the extension of slavery. He was raised in Manhattan, Kansas, attended public Manhattan High School, high school there, and graduated from Kansas State Agricultural College (now Kansas State Uni ...
