Rhytidosteoidea
Rhytidosteoidea is a superfamily of Temnospondyli 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 ..., early amphibian species that existed during the Carboniferous, Permian, and Triassic periods. The taxon was established in 1965 to accommodate two new species of '' Deltasaurus'', the author recognising an alliance with previously described genera.

Temnospondyli
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 amph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deltasaurus
''Deltasaurus'' is an extinct genus of Carnian Temnospondyli, temnospondyl amphibian of the family Rhytidosteidae. Taxonomy The genus was erected in 1965 by John W. Cosgriff, when describing two new species discovered northwest Australia. The author recognised an affinity with other genera allied to the family Rhytidosteidae that had been uncovered in Africa, and proposed their arrangement to a new Superfamily (biology), superfamily Rhytidosteoidea. It is the most common animal fossil of the Blina Shale, a fossil deposit at the eastern end of the Erskine Range in the Kimberley (Western Australia), Kimberley region of Western Australia. A specimen has also been collected from the Knocklofty Sandstone deposit in Tasmania. The genus places two fossil taxa, ''Deltasaurus kimberleyensis'', the type species which grew to around 90 centimetres in length, and ''Deltasaurus pustulatus'', also described by Cosgriff in 1965. The genus has been variously placed in subsequent arrangeme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indobrachyopidae
''Indobrachyops'' is an extinct genus of temnospondyl amphibian from the Early Triassic of India. It is known from a nearly complete fossil skull that was first described by paleontologists Friedrich von Huene and M. R. Sahni in 1958 from the Panchet Formation in Raniganj Coalfield. ''Indobrachyops'' belongs to a group of mostly semi-aquatic temnospondyls called Stereospondyli, but its exact placement within the group has been uncertain since its first description. Classification Huene and Sahni considered ''Indobrachyops'' to be part of the family Brachyopidae, which includes several aquatic temnospondyls with large rounded heads. However, later studies noted several features of ''Indobrachyops'' that set it apart from brachyopids, including closely spaced nostrils and a different pattern of pits and grooves on the skull roof. In 1979, J. W. Cosgriff and J. M. Zawiskie placed ''Indobrachyops'' in a new family called Indobrachyopidae along with the poorly known temnospondyls '' Ma ...
