Warrenisuchus
''Warrenisuchus'' is an extinct genus of temnospondyl amphibian from the Early Triassic of Queensland, Australia. It belongs to a diverse group of Triassic temnospondyls called Capitosauria. The type species ''Warrenisuchus aliciae'' was erected in 2009. ''W. aliciae'' was originally described as a species of ''Parotosuchus'' in 1988, which is known from other species that have been found in Europe, Africa, and Antarctica. In 2000 it was then assigned to a new genus called ''Rewanobatrachus'' along with the newly named species ''R. gunganj'', which was declared the type species of the genus. However, ''R. gunganj'' was later reclassified as a species of ''Watsonisuchus'', invalidating the name ''Rewanobatrachus'' and requiring that ''R. aliciae'' be placed in its own genus, which was named ''Warrenisuchus''. However, several studies suggest that ''Warrenisuchus aliciae'' may be a species of ''Watsonisuchus'' as well. Unlike most capitosaurs, ''Warrenisuchus'' is known from many juv ...

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 it ...

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic span the in ...

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 ...

Tatrasuchus Wildi
''Tatrasuchus'' is an extinct genus of temnospondyl amphibian from the Middle Triassic of Poland. It is classified as a member of the family Cyclotosauridae or Mastodonsauridae. It is closely related to the genus ''Cyclotosaurus''. The type species, ''Tatrasuchus kulczyckii'', was named in 1996. Damiani (2001) considered genus '' Kupferzellia'' Schoch (1997) from Middle Triassic of Germany to be a junior synonym of ''Tatrasuchus'', and recombined its type species, ''K. wildi'' as the second species of ''Tatrasuchus''. This classification was followed by some authors, e.g. Fortuny ''et al.'' (2011); other authors, e.g. Schoch (2008), maintain ''Tatrasuchus'' and ''Kupferzellia'' as distinct genera.

Cyclotosaurus Robustus
''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 ...

Stanocephalosaurus Pronus
''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.
