Mentosaurus is an extinct genus of prehistoric amphibian. [1] [2] It lived around 247-242 million years ago.
M. waltheri was identified in Germany in 1930 by Walter Karl Johann Roepke. [3]
Almasaurus is an extinct genus of trematosaurian temnospondyl within the family Latiscopidae. It is known from several skulls and some postcranial material found from the Argana Formation in Morocco, which dates back to the Late Triassic.
Actiobates is an extinct genus of trematopid temnospondyl that lived during the Late Carboniferous. It is known from the Garnett Quarry in Kansas.
Abiadisaurus is an extinct genus of prehistoric amphibian from the Temnospondyli clade. It is known solely from the Late Triassic Adigrat Sandstone of Ethiopia.
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. 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.
Bulgosuchus is an extinct genus of prehistoric amphibians, known from an incomplete mandible and a femur recovered from the Bulgo Sandstone at Long Reef in Sydney, Australia. The type species is Bulgosuchus gargantua, which was named in 1999.
Chomatobatrachus is a genus of prehistoric temnospondyl from the Triassic.
Dolichopareias is an extinct genus of prehistoric amphibian.
Notobrachyops is a genus of brachyopid temnospondyl amphibian. It is known from a skull roof impression found in the Ashfield Shale of Mortdale, New South Wales, Australia. The Ashfield Shale has also yielded a shark species, a lungfish species, six species of paleoniscid fish, a species of holostean fish, a subholostean fish, and the labyrinthodont amphibian Paracyclotosaurus davidi.
Limnerpeton is an extinct genus of dissorophoidean euskelian temnospondyl within the family Amphibamidae.
Leiocephalikon is an extinct genus of microsaur within the family Gymnarthridae. The type species is Amblyodon problematicum named by John William Dawson in 1882. Its fossil was found in the Joggins Formation which hailed from Carboniferous period. Although sometimes regarded as primitive gymnarthrids, Leiocephalikon classification is still debated as its fossil is scarce.
Kestrosaurus, occasionally misspelt as Kerstisaurus, is an extinct genus of Triassic capitosauroid temnospondyl amphibian within the family Mastodonsauridae.
Mordex is an extinct genus of temnospondyls from Carboniferous of the Czech Republic.
Ricnodon is an extinct genus of microsaur within the family Hapsidopareiontidae. The genus name means ‘wrinkled tooth’ from Ancient Greek ῥικνός and odôn. The specific name honors Edward Drinker Cope.
Rhinesuchoides is an extinct genus of prehistoric temnospondyl in the family Rhinesuchidae. It contains two species, R. tenuiceps and R. capensis, both from the Karoo Supergroup of South Africa. The latter was formerly a species of Rhinesuchus.
Wellesaurus is an extinct genus of mastodonsauroid temnospondyl. They were amphibious carnivores that lived in freshwater environments.
Palaeomolgophis is an extinct genus of eel-like prehistoric amphibian containing a single species—Palaeomolgophis scoticus. Their limbs are much reduced, and they were probably fully aquatic.
Tupilakosaurus is an extinct genus of dvinosaurian temnospondyl within the family Tupilakosauridae.
Trematosuchus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae from South Africa. The type species was first named by Haughton in 1915 as Trematosaurus sobeyi. It was assigned to its own genus, Trematosuchus, by D.M.S. Watson in 1919.
Trachystegos is an extinct genus of microsaur within the family Pantylidae.
Thoosuchus 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. The benthosuchids were originally composed of the majority of basal trematosaurian forms regarded as the ancestors of the trematosaurids. Although the genus was first named in 1940, material from one species, E. yakovlevi, was originally tentatively referred to Trematosuchus in 1926.
