Conjunctio Multidens
''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. Carroll in 1964. History of study The holotype specimen was found in 1911 in the Lower Permian Abo Formation in New Mexico ) , population_demonym = New Mexican ( es, Neomexicano, Neomejicano, Nuevo Mexicano) , seat = Santa Fe , LargestCity = Albuquerque , LargestMetro = Tiguex , OfficialLang = None , Languages = English, Spanish ( New Mexican), Navajo, Ker .... It consists of the skull and postcranial material including femora, humeri, scapulae, pelvis, a section of the vertebral column, and osteoderms. It was originally described by Case et al. (1913) as a referred specimen of ''Aspidosaurus'' (sometimes "''Broiliellus''") ''novomexicanus'' but was subsequently determined to be a distinct species by Carroll (1964).

Permian
The Permian ( ) is a geologic period and 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 period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broiliellus Brevis
''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 Ferdinand B ...

Fossil Taxa Described In 1964
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Cisuralian Temnospondyls Of North America
The Cisuralian is the first series/epoch of the Permian. The Cisuralian was preceded by the Pennsylvanian and followed by the Guadalupian. The Cisuralian Epoch is named after the western slopes of the Ural Mountains in Russia and Kazakhstan and dates between 298.9 ± 0.15 – 272.3 ± 0.5 Mya. The Cisuralian is often synonymous with the informal terms early Permian or lower Permian. It corresponds approximately with the Wolfcampian in southwestern North America. The series saw the appearance of beetles and flies and was a relatively stable warming period of about 21 million years. Name and background The Cisuralian is the first series or epoch of the Permian. The Cisuralian was preceded by the last Pennsylvanian epoch (Gzhelian) and is followed by the Permian Guadalupian Epoch. The name "Cisuralian" was proposed in 1982, and approved by the International Subcommission on Permian Stratigraphy in 1996. The Cisuralian Epoch is named after the western slopes of the Ural Mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dissorophids
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.

Zygosaurus
''Zygosaurus'' is an extinct genus of dissorophid temnospondyl from the Middle-Late Permian of Russia. It was described in 1848 by Eduard Eichwald, making it the first dissorophid to be described and is known from a single species, ''Zygosaurus lucius''. The location of the holotype, and only known specimen, is unknown, and although casts are reposited in several institutions, little is known about this taxon beyond qualitative aspects of the skull (e.g., preorbital length twice as long as postorbital length; skull width greatest at mid-length of orbits). The skull was estimated to be around 20 cm in length, making it one of the largest dissorophids, being only slightly smaller than ''Kamacops ''Kamacops'' is a genus of dissorophid temnospondyls known from the Middle to Late Permian of Russia that was described by Yuri Gubin in 1980.

Kamacops
''Kamacops'' is a genus of dissorophid temnospondyls known from the Middle to Late Permian of Russia that was described by Yuri Gubin in 1980. It is known from a single species, ''Kamacops acervalis,'' material of which is currently reposited in the Paleontological Institute of the Russian Academy of Sciences. ''Kamacops'' is one of the youngest dissorophids, along with '' Iratusaurus'' and '' Zygosaurus'' from Russia and ''Anakamacops'' from China and was one of the largest known dissorophids, with an estimated skull length of 24–30 cm. It is typically recovered as being most closely related to ''Zygosaurus'' and to the North American ''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 Woehri
''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.
