Paracyclotosaurus is an extinct genus of temnospondyl, which would have appeared similar to today's salamander – but much larger, measuring up to 2.45 m (8.0 ft) long and weighing between 159 and 365 kg. 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 an extinct genus of prehistoric marine coelacanth which lived during the Late Devonian period.
Brachyopoidea is a superfamily of temnospondyls that lived during the Mesozoic. It contains the families Brachyopidae and Chigutisauridae. The earliest records of brachyopids are from the Lower Triassic in Australia. The latest-surviving member of the superfamily is the chigutisaurid Koolasuchus from the Early Cretaceous of Australia.
Acroplous is an extinct genus of dvinosaurian Temnospondyli within the family Eobrachyopidae.
Bothriceps is an extinct genus of stereospondyl temnospondyl. It is a member of the infraorder Trematosauria and is the most basal brachyopomorph known. It may be 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.
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. This specimen may represent a larval stage, as denoted by the presence of external gills, making it the first evidence of larval development in stereospondyls.
Subcyclotosaurus is an extinct genus of carnivorous mastodonsaurid temnospondyl. It is known from a single partial skull from the Hawkesbury Sandstone formation in Australia.
Brookvalia is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Middle Triassic epoch.
Helichthys is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch in what is now South Africa.
Agecephalichthys is an extinct genus of prehistoric freshwater "palaeonisciform" ray-finned fish that lived during the Anisian age. It contains a single species, A. granulatus from the Hawkesbury Sandstone in what is now New South Wales, Australia.
Chrotichthys is an extinct genus of prehistoric freshwater ray-finned fish that lived in the Anisian stage of the Middle Triassic epoch. It contains a single species, C. gregarius, known from the Terrigal Formation of New South Wales, Australia.
Urosthenes is an extinct genus of prehistoric bony fish that lived during the Lopingian to Middle Triassic epochs in what is now New South Wales, Australia.
Xenobrachyops is an extinct genus of temnospondyl amphibian from the Olenekian Arcadia Formation 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.
