Intasuchus
''Intasuchus'' is an extinct genus of temnospondyl amphibian from the Middle Permian of Russia. It is known from a single species, ''Intasuchus silvicola'', which was named in 1956. ''Intasuchus'' belongs to the family Intasuchidae and is probably its sole member, although other taxa such as ''Syndyodosuchus'' and ''Cheliderpeton'' have been assigned to the family in the past. ''Intasuchus'' most likely belongs to the group Archegosauroidea, Permian relatives of the large, mostly Mesozoic temnospondyl clade Stereospondyli. Description ''Intasuchus'' has a long, flattened skull that narrows slightly toward the front. Prominent ridges run along the skull surface from the eye sockets to the nostril openings. The otic notch at the back of the skull is relatively narrow in comparison to other temnospondyls, although it extends as a groove along the sides of the skull table. ''Intasuchus'' has large teeth on the roof of its mouth, with a large row between two openings of the palate call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archegosauroidea
Archegosauroidea is an extinct superfamily of Permian temnospondyls. The superfamily is assigned to the clade Stereospondylomorpha and is the sister taxon to the suborder Stereospondyli. It includes the families Actinodontidae and Archegosauridae, and possibly the genus ''Intasuchus'', which is placed within the monotypic family Intasuchidae. They were fully aquatic animals, and were metabolically and physiologically more similar to fish than modern amphibians.Florian Witzmann; Elizabeth Brainerd (2017).

Cheliderpeton
''Cheliderpeton'' (often misspelled ''Chelyderpeton'') is an extinct genus of temnospondyl amphibian. It lived during the Early Permian in what is now Europe. Fossils have been found from the Ruprechtice horizon of the Intrasudetic Basin of Bohemia in the Czech Republic, as well as the Saar-Nahe Basin of southwestern Germany. ''Cheliderpeton'' had a 16 cm skull, and reached about 65 cm in length.http://www.angellis.net/Web/PDfiles/amphs.pdf The type species of ''Cheliderpeton'' is ''Chelidosaurus vranyi'', named in 1877 by the Czech (people), Czech paleontologist Antonin Fritsch and found from the Czech Republic. The preoccupied generic name, referring to the trunk armour of turtles, was first changed into ''Chelydosaurus'' in 1885 and finally into ''Cheliderpeton'' in 1887. A second species named ''C. latirostre'' was described in 1993 by J. A. Boy from Germany, after having been assigned to ''Archegosaurus''. It differs from the type in having a less extensive preor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Temnospondyl
Temnospondyli (from Greek language, Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order (biology), order of small to giant tetrapods—often considered Labyrinthodontia, primitive amphibians—that flourished worldwide during the Carboniferous, Permian, and Triassic periods. A few species continued into the Jurassic and Cretaceous periods. Fossils have been found on every continent. 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 considered amphibians, many had cha ...

Guadalupian
The Guadalupian is the second and middle series/epoch of the Permian. The Guadalupian was preceded by the Cisuralian and followed by the Lopingian. It is named after the Guadalupe Mountains of New Mexico and Texas, and dates between 272.95 ± 0.5 – 259.1 ± 0.4 Mya. The series saw the rise of the therapsids, a minor extinction event called Olson's Extinction and a significant mass extinction called the end-Capitanian extinction event. The Guadalupian was previously known as the Middle Permian. Name and background The Guadalupian is the second and middle series or epoch of the Permian. Previously called Middle Permian, the name of this epoch is part of a revision of Permian stratigraphy for standard global correlation. The name "Guadalupian" was first proposed in the early 1900s, and approved by the International Subcommission on Permian Stratigraphy in 1996. References to the Middle Permian still exist. The Guadalupian was preceded by the Cisuralian and followed by the Lop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archegosaurus Dyscriton
''Archegosaurus'' is a genus of temnospondyl amphibian which lived during the Asselian to Wuchiapingian stages of the Permian, around 299-253 million years ago. The remains of this animal, consisting of at least 90 partial skeletons (mostly skulls), have been found in Germany. The name ''Archegosaurus'' was coined by Goldfuss in 1847. ''Archegosaurus'' is a member of Archegosauridae and is that family's type genus. Classification In 1938, paleontologist Margaret C. Steen described a temnospondyl from the Permian-age Ruprechtice assemblage in northeast Bohemia. Steen named it ''Memonomenos dyscriton'' on the basis of a skull that was narrower than others in the Ruprechtice. It was classified as an anthracosaur, a group closely related to reptiles. Both ''Memonomenos'' and embolomere anthracosaurs had vertebrae that were divided into several parts, including a pleurocentrum and intercentrum. Animals with this type of divided vertebrae were said to be rachitomi. During the early tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ance ...

Sclerocephalus Haeuseri
''Sclerocephalus'' is an extinct genus of temnospondyl amphibian from the lowermost Permian of Germany and Czech Republic with four valid species, including the type species ''S. haeuseri''. It is one of the most completely preserved and most abundant Palaeozoic tetrapods. ''Sclerocephalus'' was once thought to be closely related to eryopoid temnospondyls, but it is now thought to be more closely related to archegosauroids. It is the only genus in the family Sclerocephalidae. Description and lifestyle The adults animals reached a body length of ca. 150 cm, and had an elongate trunk and a laterally compressed tail. In some specimens lateral line sulci are retained. These body features suggest an aquatic mode of life, with aquatic larvae that probably breathed with external gills like modern tadpoles, while the adults breathed with lungs. ''Sclerocephalus'' underwent significant changes during its ontogeny, for example the eyes are much larger and the tail much longer in lar ...
