Mastodonsauridae
Mastodonsauridae is a family of capitosauroid temnospondyls. Fossils belonging to this family have been found in North America, Greenland, Europe, Asia, and Australia. The family Capitosauridae is synonymous with Mastodonsauridae. Description Size Mastodonsaurids were generally large amphibians, with some length estimates ranging from 3 to 6 meters. Some genera, like '' Mastodonsaurus'' and '' Cyclotosaurus'' were specially large, reaching at least 4 meters or more. Other genera like '' Parotosuchus'' and ''Paracyclotosaurus'' only reached 2 meters or more in length, but it's still pretty large compared to modern-day amphibians. Distinguishing features Some mastodonsaurids including ''Parotosuchus'' were covered in a scaly skin, unlike the smooth skin of modern-day amphibians, and probably moved with an eel-like motion in the water. Another peculiar mastodonsaurid is ''Sclerothorax'', with unusual features including its elongated neural spines. The neural spines are talles ...

Stanocephalosaurus
''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. Like other temnospondyls, ''Stanocephalosaurus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parotosuchus
''Parotosuchus'' is an extinct genus of capitosaurian temnospondyl amphibians within the family Mastodonsauridae. Fossils are known from the Early Triassic of Europe, Africa, Australia, and Antarctica. It was about long and likely lived in aquatic environments such as lakes and rivers. ''Parotosuchus'' was covered in a scaly skin, unlike the smooth skin of modern-day amphibians, and probably moved with an eel-like motion in the water. ''Parotosuchus'' was originally named ''Parotosaurus''. However, the name ''Parotosaurus'' was preoccupied by a genus of skinks, and in 1968 the name ''Parotosuchus'' was proposed as a replacement. The name ''Archotosaurus'' was also proposed as a replacement name in 1976, although the author who proposed this was unaware that ''Parotosuchus'' was already in use. Because the name ''Parotosuchus'' was erected earlier than ''Archotosaurus'', it has priority. References Further reading *Parotosuchus (Temnospondyli: Mastodonsauridae) from the Tr ...

Rhadalognathus
''Rhadalognathus'' was a prehistoric crocodile-like amphibian that belongs to the Mastodonsauridae family. Not much is known about this creature but it lived in the Triassic period. ''Rhadalognathus'' is also the name of the genus in which the organism belongs within. ''Rhadalognathus'' was found in northern Arizona Arizona ( ; nv, Hoozdo Hahoodzo ; ood, Alĭ ṣonak ) is a state in the Southwestern United States. It is the 6th largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is part of the Fou ..., US, by S. P. Welles in 1947.

Xenotosuchus
''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.

Bukobaja
''Bukobaja'' is an extinct genus of mastodonsaurid temnospondyl from the middle Triassic of Russia. It contains a single species, ''Bukobaja enigmatica''. ''Bukobaja'' mainly occurs in the Bukobay Svita as part of the Ladinian?-age "'' Mastodonsaurus'' fauna", a section of Russian Triassic biostratigraphy characterized by ''"Mastodonsaurus" torvus''. It was also present in the underlying Donguz Svita ("''Eryosuchus'' fauna"). ''Bukobaja'' appears to be a valid genus similar to, yet distinct from, ''Mastodonsaurus''. Despite appearing to possess several unique features, ''Bukobaja'' is still known from very few remains. This has led to difficulties in determining its relations more precisely than "Mastodonsauridae ''incertae sedis''". It has also been compared to trematosaurids.

Cherninia
''Cherninia'' is an extinct genus of mastodonsaurid temnospondyl. The type species, ''Cherninia denwai'', is known from the Denwa Formation of India. It is based on a massive skull, ISI A 54, which was originally considered a species of ''Parotosuchus'' in 1998 before being given its own genus in 2001. Another species, ''Cherninia megarhina'', is known from the Upper Ntawere Formation of Zambia Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are t .... ''C. megarhina'' is based on another large skull, BP/1/4223, which had also been previously referred to ''Parotosuchus''. Though not as well-preserved as the skull of ''C. denwai'', BP/1/4233 was described earlier in 1974. It was described by Sharon Chernin, a paleontologist at the Bernard Price Institute and the namesake of the genus. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclotosaurus
''Cyclotosaurus'' is an extinct genus of temnospondyl within the family Mastodonsauridae. It was of great size for an amphibian, had an elongated skull up to . Etymology The name means "round eared lizard" in Ancient Greek, derived from round openings or fenestrae in the cheeks, which are thought to contain structures of the middle ear. History German naturalist Eberhard Fraas erected the genus ''Cyclotosaurus'' in 1889, with ''C. robustus'' (previously ''Mastodonsaurus robustus'') as the type species. Several species are known, mainly from Germany and Poland in Central Europe, as well as East Greenland and Thailand. The relationships between species is unclear. ''"Labyrinthodon" pachygnathus'' Owen, 1842 and ''"L." leptognathus'' Owen, 1842 were transferred to ''Cyclotosaurus'', as ''C. pachygnathus'' and ''C. leptognathus'', by Paton (1974). However, Damiani (2001) assigned the two species to Mastodonsauroidea indeterminate and Stereospondyli indeterminate. Palaeontology ...

Temnospondyl
Temnospondyli (from Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order of small to giant tetrapods—often considered 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 characteristics, such as scales and armour-like bony ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
