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 Ferdina ...

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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 nam ...

Amphibamidae
The Amphibamidae are an extinct family of dissorophoid temnospondyls known from Late Carboniferous-Early Permian strata in the United States. Classification Amphibamidae has traditionally included small-bodied, terrestrial dissorophoids. The name is attributed to Moodie (1909), but it was rarely used because it originally referred only to '' Amphibamus''. Similar monogeneric families were also erected for other small, terrestrial dissorophoids (e.g., Doleserpetontidae), and most of the taxa now recognized as amphibamiforms were placed within the Dissorophidae. Clack & Milner (1993) revived the Amphibamidae to include ''Amphibamus, Platyrhinops, Doleserpeton,'' and '' Tersomius'.'' Daly (1994) further expanded the composition of the Amphibamidae to include the newly described ''Eoscopus'' as well as the Early Triassic form ''Micropholis''. She suggested that the micromelerpetids were also amphibamids, which has not been validated by more recent workers. Subsequent phylogenet ...

Polytomy
An internal node of a phylogenetic tree is described as a polytomy or multifurcation if (i) it is in a rooted tree and is linked to three or more child subtrees or (ii) it is in an unrooted tree and is attached to four or more branches. A tree that contains any multifurcations can be described as a multifurcating tree. Soft polytomies vs. hard polytomies Two types of polytomies are recognised, soft and hard polytomies. Soft polytomies are the result of insufficient phylogenetic information: though the lineages diverged at different times – meaning that some of these lineages are closer relatives than others, and the available data does not allow recognition of this. Most polytomies are soft, meaning that they would be resolved into a typical tree of dichotomies if better data were available. In contrast, a hard polytomy represents a true divergence event of three or more lineages. Applications Interpretations for a polytomy depend on the individuals, that are represe ...

Doleserpeton
''Doleserpeton'' is an extinct, monospecific genus of dissorophoidean temnospondyl within the family Amphibamidae that lived during the Upper Permian, 285 million years ago. ''Doleserpeton'' is represented by a single species, ''Doleserpeton annectens'', which was first described by John R. Bolt in 1969.Sigurdsen, Trond, and John R. Bolt. "The Lower Permian Amphibamid Doleserpeton (temnospondyli: Dissorophoidea), the Interrelationships of Amphibamids, and the Origin of Modern Amphibians." Journal of Vertebrate Paleontology. 30.5 (2010): 1360-1377. Print. Fossil evidence of ''Doleserpeton'' was recovered from the Dolese Brothers Limestone Quarry in Fort Sill, Oklahoma. The genus name ''Doleserpeton'' is derived from the initial discovery site in Dolese quarry of Oklahoma and the Greek root "herp-", meaning "low or close to the ground". This transitional fossil displays primitive traits of amphibians that allowed for successful adaptation from aquatic to terrestrial environments. In ...
