Batrachosaurus is an extinct genus of prehistoric brachyopoid amphibian that lived in Germany during the Middle Triassic (Ladinian). [1] The genus was named by Joseph Fitzinger in 1837 and the type species, B. jaegeri, was named three years later in 1840. It may have been the same animal as Mastodonsaurus . [2]
The Alytidae are a family of primitive frogs. Their common name is painted frogs or midwife toads. Most are endemic to Europe, but three species occur in northwest Africa, and a species formerly thought to be extinct is found in Israel.
Mastodonsaurus is an extinct genus of temnospondyl amphibian from the Middle Triassic of Europe. It belongs to a Triassic group of temnospondyls called Capitosauria, characterized by their large body size and presumably aquatic lifestyles. Mastodonsaurus remains one of the largest amphibians known, and may have exceeded 6 meters in length.
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.
Arizonerpeton is an extinct genus of nectridean lepospondyl. It contains a single species, Arizonerpeton wellsi. It lived in what is now the Swisshelm Mountains of modern-day Arizona, United States. This locality belongs to the Black Prince Limestone Formation, which is dated to the middle Pennsylvanian sub-period of the Carboniferous period.
Angusaurus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae.
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.
Brevidorsum is an extinct genus of dissorophoidean euskelian temnospondyl within the family Dissorophidae.
Branchierpeton is an extinct genus of dissorophoidean euskelian temnospondyl within the family Micromelerpetontidae native to Africa.
Batrachosuchoides is an extinct genus of prehistoric amphibian from the Early Triassic of Russia. It was found in the Baskunchakskaia Series and the Lestanshorskaya Svita.
Ctenerpeton is an extinct genus of nectridean lepospondyl within the family Urocordylidae.
Crinodon is an extinct genus of microsaur within the family Tuditanidae. The type and only species C. limnophyes was found in Carboniferous deposits of Nyrany and described by M. C. Steen in 1938 as Ricnodon limnophyes. It was assigned to the new genus Crinodon by R. L. Carroll and P. Gaskill in 1978.
Cocytinus is an extinct genus of prehistoric amphibian.
Erythrobatrachus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. The sole species Erythrobatrachus noonkanbahensis was separated to a monotypic genus, distinguishing it from related taxa when the description was published in 1972. The type material was a matrix cast revealing the impression of several fragments of skull excavated at the Blina Shale formation in the northwest of the Australian continent. The genus name is derived from ancient Greek, combining terms for red, erythro, with frog, batrachos, to describe the iron staining of the fossilised amphibian specimens. The type location described by the specific epithet was Noonkanbah Station.
Erpetosaurus is an extinct genus of dvinosaurian temnospondyl within the family Eobrachyopidae. Erpetosaurus is only known from the Upper Freeport Coal, Allegheny Group, Middle Pennsylvanian of Linton, Ohio, USA. Some unique features of the temnospondlys are that they have a single fang on each premaxilla on the anterior maxilla for the reception of two dentary fangs; and an elongate, tube-like backside extension of the parasphenoid, both hinting to an aquatic hunting lifestyle.
Deltacephalus is an extinct genus of prehistoric stereospondyl temnospondyl from Madagascar.
Cosgriffius is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae. It was described in 1993 by Samuel P. Welles based on a single partial skull from the well-known Meteor Crater Quarry in Arizona that also produced more abundant remains of the capitosaur Wellesaurus peabodyi. The skull was long and slender, features typically associated with the trematosaurid subfamily Lonchorhynchinae. This is the only trematosaurid known from western North America.
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.
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, US, by S. P. Welles in 1947. The size of the organism is unknown but its skull is about 17in long and weighs 7lbs.
The Bukobay Svita is a Middle Triassic geological unit in Russia. It is composed primarily of red or grey lacustrine sediments, reconstructing a humid and marshy depositional environment. Bukobay is the youngest section of a Triassic terrestrial succession exposed south of the Ural Mountains. It is equivalent to a biostratigraphic unit, the Bukobay Gorizont, which is also called the "Bukobay Horizon" or "Mastodonsaurus" fauna).
