Parotosuchus
''Parotosuchus'' is an extinct genus of capitosaurian temnospondyls 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. Phylogeny ''Parotosuchus'' in a cladogram after Novikov (2018) with only Early Triassic Eastern Eur ...

Capitosauridae
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 large compared to most 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 tallest at the ...

Lydekkerinidae
Lydekkerinidae is a family of stereospondyl temnospondyls that lived in the Early Triassic period. During this time period, lydekkerinids were widely distributed, with putative remains reported from Russia, Greenland, India, South Africa, Madagascar, Australia, and Antarctica. In contrast to most other stereospondyls, lydekkerinids were relatively small-bodied (most with skulls less than 10 cm in length). The type genus is ''Lydekkerina'', the namesake of the family and the best-known lydekkerinid. Description The identification of features shared among lydekkerinids (synapomorphies) necessarily varies depending on which taxa are considered to belong to this group (see further in next section). In the most expansive concept, the family includes the eponymous ''Lydekkerina'' (and junior synonyms like '''Broomulus''' and '''Limnoiketes'''), ''Eolydekkerina'' from South Africa, ''Deltacephalus'' from Madagascar, ''Luzocephalus'' from Russia and Greenland (which includes the '''Aqui ...

Qantas (genus)
''Qantas'' is a genus of trematosauroid temnospondyl from the Early Triassic. Fossils have been found from the Kamennyi Yar Formation in Borsky District, Samara Oblast. The type species ''Qantas samarensis'' was named in 2012 and placed in the family Benthosuchidae, as it was viewed as a close relative of ''Benthosuchus''. The subfamily Qantasinae was established to include ''Qantas'', and possibly the genus ''Tirraturhinus''. ''Qantas'' is named after the Australian airline Qantas, which supported the original study of the fossils.

Capitosauria
Capitosauria is an extinct group of large temnospondyl amphibians with simplified stereospondyl vertebrae. Mainly living as piscivores in lakes and rivers, the Capitosauria and its sister taxon Trematosauria were the only major labyrinthodonts that existed during the Mesozoic in ecological niches broadly similar to those of modern crocodiles, and some grew to very large sizes. At 6 meters in length, the Mid-Triassic '' Mastodonsaurus giganteus'' is not only thought to have been the largest capitosaur, but possibly also the largest amphibian to have lived. The latest known remains are from the Rhaetian of Germany and are referred to '' Cyclotosaurus''. Capitosauria was first named by Schoch and Milner (2000) and further described by Yates and Warren (2000), who assigned ''Lydekkerina'' and Mastodonsauroidea to it. It was described by Damiani (2001) under the name Mastodonsauroidea. In their phylogenetic analysis of temnospondyls, Ruta ''et al.'' (2007) placed ''Lydekkerina'' and ...

Thoosuchus
''Thoosuchus'' (meaning "active crocodile") is an extinct genus of basal trematosauroid trematosaurian temnospondyl. Fossils have been found from Russia and date back to the Early Triassic. It is the type genus of the family Thoosuchidae, formerly called the subfamily Thoosuchinae and placed within Benthosuchidae. Efremov, I. A. (1940). Preliminary description of the new Permian and Triassic Tetrapoda from U.S.S.R. ''Trudy Paleontologicheskogo Instituta'' 10:1–140. The benthosuchids were originally composed of the majority of basal trematosaurian forms regarded as the ancestors of the trematosaurids. Discovery and naming Although the genus was first named in 1940, material from one species, ''E. yakovlevi'', was originally tentatively referred to '' Trematosuchus'' in 1926. Russian paleontologist Ivan Yefremov fremovnamed it ''Thoosuchus'' "active crocodile" (from Ancient Greek θοός (thoos) "nimble, active" and σοῦχος (soukhos) "crocodile") in 1940, "in view of ...
