Cleithrolepis is an extinct genus of ray-finned fish that lived in during the Anisian age (Middle Triassic epoch) in what is now Australia (New South Wales, Tasmania) and Libya. A species from the Carnian (Late Triassic) of Germany, C. brueckneri, was also ascribed to Cleithrolepis. [1]
The genus grew to about 30 centimetres (12 in) long. It had a weak lower jaw with teeth only at the tip. [2]
Cleithrolepis lived in rivers, billabongs and lakes in the large braided river system that deposited the Hawkesbury Sandstone in what is now New South Wales, with fossils found in shale lenses within the sandstone. [3] Fossils were also found in Tasmania (Knocklofty Formation) and in a drill core sample from Libya. [4]
The Sydney Basin is an interim Australian bioregion and is both a structural entity and a depositional area, now preserved on the east coast of New South Wales, Australia and with some of its eastern side now subsided beneath the Tasman Sea. The basin is named for the city of Sydney, on which it is centred.
Dicellopyge is an extinct genus of freshwater ray-finned fish that lived during the Anisian age of the Middle Triassic epoch in what is now South Africa. It was originally named "Dicellopygae" by James Brough but the name was later corrected to Dicellopyge by Peter Hutchinson.
Deltasaurus is an extinct genus of Carnian temnospondyl amphibian of the family Rhytidosteidae.
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.
Australosomus is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic epoch in what is now Greenland, Kenya, Tanzania, Madagascar, South Africa and Canada.
Tripelta is an extinct genus of prehistoric bony fish that lived during the Anisian age in what is now New South Wales, Australia.
Dictyopyge is an extinct genus of prehistoric freshwater bony fish. Two species are recognized, D. macrurus and D. meekeri, which both lived during the Carnian age in what is now Virginia, United States.
Helichthys is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch in what is now South Africa.
Sakamenichthys is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch in what is now Madagascar. Fossils were recovered from beds of the Middle Sakamena Formation of the Beroroha basin in the southern part of the island.
Agecephalichthys is an extinct genus of prehistoric freshwater bony fish that lived during the Anisian age in what is now New South Wales, Australia.
Enigmatichthys is a genus of extinct semionotiformid bony fish that lived during the Middle Triassic epoch of what is now Australia.
Eosaurichthys is an extinct saurichthyid ray-finned fish that lived during the late Permian epoch in what is now China. It closely resembles its daughter genus, Saurichthys, in both form and morphology.
Aphelolepis is an extinct genus of prehistoric bony fish that lived during the Ladinian age of the Middle Triassic epoch in what is now Franconia, Germany.
Dorsolepis is an extinct genus of prehistoric bony fish that lived during the Anisian age in what is now France (Alsace). Fossils were found in the Grès à Voltzia.
Alleiolepis is an extinct genus of prehistoric bony fish, which lived during the Ladinian age of the Middle Triassic epoch in what is now Franconia, Germany. It was first named Leiolepis, but because this genus name is preoccupied by an extant lizard, the genus name of the Triassic fish was changed to Aleiolepis.
Archaeomaene is an extinct genus of ray-finned fish that lived in what is now Australia during the Late Jurassic. It is a monotypic genus, containing only the species Archaeomaene tenuis, which is known from the Talbragar River beds of New South Wales.
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.
Pristisomus is an extinct genus of prehistoric bony fish that lived during the Anisian age in what is now New South Wales, Australia. Fossils are derived from the Sydney sandstone.
Geologically the Australian state of New South Wales consists of seven main regions: Lachlan Fold Belt, the Hunter-Bowen Orogeny or New England Orogen (NEO), the Delamerian Orogeny, the Clarence Moreton Basin, the Great Artesian Basin, the Sydney Basin, and the Murray Basin.
Bobasatraniiformes is an extinct order of durophagous ray-finned fish that existed from the late Permian to the Middle Triassic in both marine and freshwater environments. The order includes two families: Bobasatraniidae, with the genera Bobasatrania, Ebenaqua, and Ecrinesomus, and Dorypteridae, comprising only the genus Dorypterus (monotypy). Bobasatraniiformes had a somewhat global distribution; fossils are found in Africa (Madagascar), Asia (Pakistan), Australia, Europe, and North America.
