Eryosuchus BW
''Eryosuchus'' is an extinct genus of capitosauroid temnospondyl amphibian from the Middle Triassic of northern Russia. It was a very large predator: the largest specimen known could reach up to 3.5 m (11.5 ft) in length, with a skull over 1 m long. History of study ''Eryosuchus'' was named by Ochev (1966) based on the type species, ''E. tverdochlebovi'' from exposures of the Donguz Formation in Orenburgskaya Oblast. In the same publication, Ochev also named ''E. garjainovi'' and ''E. antiquus'', both from the same formation and oblast as ''E. tverdochlebovi''. Several other species previously placed in other genera have sometimes been placed in ''Eryosuchus'', such as "''Stanocephalosaurus''" ''pronus'' from Tanzania and ''"''Stanocephalosaurus" ''rajareddyi'' from India, but this is largely disputed, as is the validity of ''E. antiquus'', which is only based on a lower jaw fragment. These species, as well as more confidently assigned species of ''Eryosuchus,'' we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Triassic
In the geologic timescale, the Middle Triassic is the second of three epochs of the Triassic period or the middle of three series in which the Triassic system is divided in chronostratigraphy. The Middle Triassic spans the time between Ma and Ma (million years ago). It is preceded by the Early Triassic Epoch and followed by the Late Triassic Epoch. The Middle Triassic is divided into the Anisian and Ladinian ages or stages. Formerly the middle series in the Triassic was also known as Muschelkalk. This name is now only used for a specific unit of rock strata with approximately Middle Triassic age, found in western Europe. Middle Triassic fauna Following the Permian–Triassic extinction event, the most devastating of all mass-extinctions, life recovered slowly. In the Middle Triassic, many groups of organisms reached higher diversity again, such as the marine reptiles (e.g. ichthyosaurs, sauropterygians, thallatosaurs), ray-finned fish and many invertebrate groups like ...

Rhineceps Nyasaensis
''Rhineceps'' is an extinct genus of temnospondyl amphibian in the family Rhinesuchidae. ''Rhineceps'' was found in Northern Malawi (formerly Nyasaland) in Southern Africa known only from its type species ''R. nyasaensis''. ''Rhineceps'' was a late Permian (256-258 Mya) semi-aquatic carnivore that lived in streams, rivers, lakes or lagoons. ''Rhineceps'' is an early divergent Stereopondyl within the family Rhinesuchidae, which only existed in the late Permian (Lopingian) and failed to survive the Permian-Triassic extinction unlike other stereospondyl families. History ''Rhineceps'' was originally discovered in the “Upper Bone Beds” of the Chiweta Beds, North Waller Area in Northern Malawi. The fossil was first described and named by Haughton in 1926, whereby he describes the fossil of a left mandibular ramus of ''R. nyasaensis'' as within the genus ''Rhinesuchus'' due to its similarity with the fossils of ''Rhinesuchus whaitsi.'' Watson later determined in a letter to P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Procyclotosaurus Stantonensis
''Procyclotosaurus'' is an extinct genus of stenotosaurid capitosaurian temnospondyl. The type species is ''P. stantonensis''. In 1904, English paleontologist Arthur Smith Woodward described it as a species of ''Capitosaurus'', ''C. stantonensis'', based on a partial skull known as R 3174. In 1958, the species was assigned to the new genus. It is known from the Lower Keuper, a European stratigraphic unit that was deposited during the late Middle Triassic.Witzmann, Florian & Sachs, Sven & Nyhuis, Christian. (2016).

Stanocephalosaurus Birdi
''Stanocephalosaurus'' (stano from Greek stenos, meaning “narrow”, cephalo from Greek kephalē, meaning “head”) is an extinct genus of large-sized temnospondyl amphibians living through the early to mid Triassic. The etymology of its name most likely came from its long narrow skull when compared to other temnospondyls. ''Stanocephalosaurus'' lived an aquatic lifestyle, with some species even living in salt lakes. There are currently three recognized species and another that needs further material to establish its legitimacy. The three known species are ''Stanocephalosaurus pronus'' from the Middle Triassic in Tanzania, ''Stanocephalosaurus amenasensis'' from the Lower Triassic in Algeria, and ''Stanocephalosaurus birdi'', from the middle Triassic in Arizona. ''Stanocephalosaurus rajareddyi'' from the Middle Triassic in central India needs further evidence in order to establish its relationship among other Stanocephalosaurs.

Paracyclotosaurus Crookshanki
''Paracyclotosaurus'' (meaning "Near Wheeled Lizard") is an extinct genus of temnospondyl amphibian, which would have appeared similar to today's salamander – but much larger, measuring up to long and weighing between . It lived in the Middle Triassic period, about 235 million years ago, and fossils have been found in Australia, India, and South Africa. Although they could live on dry land, ''Paracyclotosaurus'' probably spent most of its time in water. They had flattened bodies and elongated heads, almost long, that vaguely resembled those of modern crocodiles. Discovery and naming The type species ''P. davidi'' is only known from one complete specimen recovered from Australia. It was discovered by quarry miners in a brick pit in St. Peters in Sydney, New South Wales. The discovery, made in 1910, was from a large ironstone nodule within Ashfield Shale which contained the nearly complete skeleton. The reconstruction was finished in July 1914, and was initially determin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Cherninia'' is an extinct genus of mastodonsaurid temnospondyl. The type species, ''Cherninia denwai'', is known from the Denwa Formation of India.

Xenotosuchus Africanus
''Xenotosuchus'' is an extinct genus of mastodonsaurid temnospondyl within the family Mastodonsauridae known from the Triassic of South Africa. The genus is based on a skull originally described as ''Parotosuchus'', an animal which it resembled in general build and habit. Description Like many mastodontosaurids, it was a large animal with a large head. Its amphibian life history meant that the distinct shape of the skull roof would change from a generalized tadpole-like skull type through to the distinct adult shape. The head bones are covered in large pits and grooves, indicating extensive dermal armour on the head. Both the upper and lower jaw had tusks, those of the upper jaw being situated on a 2nd row of teeth on the vomer and palatine bone. Contrary to related forms like ''Mastodonsaurus'', the tusks of the lower jaw were of moderate size and did not penetrate the premaxilla.

Vladlenosaurus Alexeyevi
''Vladlenosaurus'' is an extinct genus of capitosaur from Russia. It lived during the late Vetlugian (Early Triassic). Based on the type of deposits it was found in, ''Vladlenosaurus'' probably inhabited lacustrine, or lake, habitats. The type species is ''V. alexeyevi'', named in 2000. Description Unlike the flatter, more rounded snouts of other capitosaurs, ''Vladlenosaurus'' had a wedge-shaped snout. This characteristic is also seen in trematosaurians, although it was independently acquired in both cases as a result of convergent evolution. Classification ''Vladlenosaurus'' is similar in appearance to the benthosuchids, a group of trematosauroid temnospondyls, but is more closely related to mastodonsauroids. Among capitosaurs, it shares many features with the basal form ''Wetlugasaurus'', also from the Early Triassic of Russia. ''Vladlenosaurus alexeyevi'' was even considered to be a species of ''Wetlugasaurus'' in a 2006 study. In a 2011 phylogenetic analysis, the first ...
