Trimerorhachidae
Trimerorhachidae is a family of dvinosaurian temnospondyls, including ''Lafonius'', ''Trimerorhachis'', ''Procuhy'' and ''Neldasaurus''. They were semiaquatic carnivores that lived from the Pennsylvanian (geology), Late Carboniferous to the Early Permian.

Dvinosauria
Dvinosaurs are one of several new clades of temnospondyls named in the phylogenetic review of the group by Yates and Warren 2000. They represent a group of primitive semi-aquatic to completely aquatic temnospondyls, and are known from the Late Carboniferous to the Early Triassic, being most common in the Permian period. Their distinguishing characteristics are a reduction of the otic notch; the loss of a flange on the rear side of the pterygoid; and 28 or more presacral vertebrae. Trimerorhachidae is the most basal family of dvinosaurs. Most other dvinosaurs are placed in the superfamily Dvinosauroidea. Within Dvinosauroidea are two families, Eobrachyopidae and Tupilakosauridae, as well as dvinosaurs that cannot be placed in either family, such as '' Dvinosaurus'' and '' Kourerpeton''. A 2008 phylogenetic analysis found Eobrachyopidae to be paraphyletic, representing a grade of basal dvinosauroids. Below is a cladogram A cladogram (from Greek language, Greek ''clados'' " ...

Trimerorhachis
''Trimerorhachis'' is an extinct genus of dvinosaurian temnospondyl within the family (biology), family Trimerorhachidae. It is known from the Early Permian of the southwestern United States, with most fossil specimens having been found in the Red Beds of Texas and Oklahoma, Texas Red Beds. The type species of ''Trimerorhachis'', ''T. insignis'', was named by American paleontologist Edward Drinker Cope in 1878. Cope named a second species from Texas, ''T. mesops'', in 1896. The species ''T. rogersi'' (named in 1955) and ''T. greggi'' (named in 2013) are also from Texas, and the species ''T. sandovalensis'' (named in 1980) is from New Mexico. Description Largest specimens of ''Trimerorhachis'' reached a length of about 1.5 meters (5 ft), although most have been no more than 1.2 meters (4 ft) in length. ''Trimerorhachis'' has a large triangular head with upward-facing eyes positioned near the front of the skull. The trunk is long and the limbs are relatively short. The presence o ...

Temnospondyl Families
Temnospondyli (from Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent. A few species continued into the Jurassic and Early Cretaceous periods, but all had gone extinct by the Late Cretaceous. During about 210 million years of evolutionary history, they adapted to a wide range of habitats, including freshwater, terrestrial, and even coastal marine environments. Their life history is well understood, with fossils known from the larval stage, metamorphosis and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted to life on land. Although temnospondyls are amphibi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Procuhy
''Procuhy'' is an extinct genus of dvinosaurian temnospondyl amphibian in the family Trimerorhachidae represented by the type species ''Procuhy nazariensis'' from the Early Permian of Brazil. History of study ''Procuhy'' was named in 2015 on the basis of a partial skull from the lower part of the Pedra de Fogo Formation in Parnaíba Basin, which is about 278 million years old. The genus name comes from the words for 'frog' (prôt) and 'fire' (cuhy) in the local Timbira language, Timbira language of the Macro-Jê languages, Macro-Jê group and refers to the name of the Pedra de Fogo Formation. The species name comes from the Nazaria Municipality where the holotype was collected from. A second specimen, discovered in 2015, was described by Marsicano et al. (2021), who provided a more complete description of this taxon. Anatomy Both specimens of ''P. nazariensis'' are relatively fragmentary, and the taxon is diagnosed only by a unique combination of characters rather than by a ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nomenclature Mammal order The technical term for mammals in the order (biology), order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, on the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods of the Carboniferous Period (or the upper of two system (stratigraphy), subsystems of the Carboniferous System). It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal Bed (geology), beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian ...
