Paracyclotosaurus is an extinct genus of temnospondyl amphibian, which would have appeared similar to today's salamander – but much larger, at up to 2.3 metres (7.5 ft) long. It lived in the Middle Triassic period, about 235 million years ago, and fossils have been found in Australia, India, and South Africa.
Chagrinia is a genus of prehistoric lobe-finned fish which lived during the Late Devonian period.
Microposaurus is an extinct genus of trematosaurid temnospondyl. Fossils are known from the Cynognathus Assemblage Zone of the Beaufort Group in South Africa and the Rouse Hill Siltstone of Australia that date back to the Anisian stage of the Middle Triassic. These aquatic creatures were the short snouted lineage from Trematosaurinae.
Bothriceps is an extinct genus of stereospondyl temnospondyl. It is a member of the infraorder Trematosauria and is the most basal brachyopomorph known. It is one of the only brachyopomorph that lies outside the superfamily Brachyopoidea, which includes the families Brachyopidae and Chigutisauridae. It shares several similarities to Keratobrachyops, another basal brachyopomorph, and may be closely related to or even synonymous with it.
Blinasaurus is a name of an extinct genus of prehistoric brachyopid found in Triassic geological formations of Australia. The type species is Platyceps wilkinsonii Stephens, 1887. The genus was established by John W. Cosgriff in 1969 to incorporate the type, discovered in New South Wales, and the author's new fossil species, Blinasaurus henwoodi, describing type material found in Blina Shale in the Kimberley region of northwest Australia.
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.
Hadrokkosaurus is an extinct genus of brachyopid temnospondyl amphibian from the Middle Triassic of the southwestern United States. It includes a single species, Hadrokkosaurus bradyi, known from the Moenkopi Formation of Arizona.
Keratobrachyops is an extinct genus of trematosaurian temnospondyl found in the Arcadia Formation of Queensland, Australia. It had been thought to be a basal chigutisaurid but is now thought to be a basal brachyopomorph closely related to the genus Bothriceps, and may even be a synonym of it.
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.
Vanastega is an extinct genus of Triassic temnospondyl amphibian in the family Brachyopidae. It is known from the Cynognathus Assemblage Zone in Burgersdorp, South Africa. The genus contains just one species, Vanastega plurimidens, the type species.
Platycepsion wilksoni is an extinct species of prehistoric amphibian, known from partial skeleton deposited in shale at the Gosford Quarry site of the Terrigal Formation in Australia.
Subcyclotosaurus is an extinct genus of carnivorous prehistoric mastodonsaurid temnospondyl amphibian. It is known from a single partial skull from the Hawkesbury Sandstone formation in Australia.
Aetheolepis is an extinct genus of ray-finned fish which lived in freshwater environments in what is now Western Australia and New South Wales during the Jurassic period. It contains one species, A. mirabilis. Aetheolepis was previously thought to be an archaeomaenid, until a 2016 study instead recovered it as a member of the family Dapediidae. Like other dapediids, it had a deep, discoid-shaped body. Fossils of A. mirabilis have been found in the Talbragar River fossil beds of New South Wales and the Colalura Sandstone of Western Australia. It was named by Arthur Smith Woodward in 1865 along with other Talbragar fish.
Strongylosteus is an extinct genus of prehistoric ray-finned fish that lived during the early Toarcian age of the Early Jurassic epoch. Its type species is Strongylosteus hindenburgi (monotypy). It is related to modern sturgeon and paddlefish (Acipenseroidei), but with a different kind of mouth than common species, made for hunting prey in open waters, with a strong lower jaw, similar to modern beluga.
Bobasatrania is an extinct genus of prehistoric bony fish that survived the Permian-Triassic extinction event. Fossils of Bobasatrania were found in beds of Changhsingian to Ladinian age. It was most speciose during the Early Triassic. The genus was named after the locality Bobasatrana in northeast Madagascar, from where the type species was described.
Xenobrachyops is an extinct genus of temnospondyl amphibian from the Triassic of Australia, describing a single species, Xenobrachyops allos. It is estimated to have been around fifty centimetres long and its diet would have consisted of fish and insects.
Ashfield Shale is part of the Wianamatta group of sedimentary rocks in the Sydney Basin. It lies directly on contemporaneously eroded Hawkesbury sandstone or the Mittagong formation. These rock types were formed in the Triassic Period. It is named after the Sydney suburb of Ashfield. Some of the early research was performed at the old Ashfield Brickworks Quarry. This rock type is often associated with the Inner West and North Shore of the city. However, it has also been recorded at Penrith, Revesby, Bilpin and Mount Irvine.
Batrachosuchus henwoodi is a fossil species of amphibian, first described as Blinasaurus henwoodi by John W. Cosgriff in 1969. The species was placed in a new generic combination when separating the genus Blinasaurus, currently subsumed as a synonym to the genus Platycepsion.
