Pristisomus is an extinct genus of prehistoric bony fish that lived during the Anisian age (Middle Triassic epoch) in what is now New South Wales, Australia. [1] Fossils are derived from the Sydney sandstone. [2]
Pristisomus comes from the Latin 'pristis' meaning 'sea monster' or 'shark' and the Greek 'soma' meaning 'body'.
Axelia is an extinct genus of prehistoric lobe-finned fish, which belonged to the family of Coelacanthidae. It lived during the Smithian age of the Early Triassic epoch in what is now Spitsbergen, Svalbard. Fossils were found in the "Fish Niveau" of the Lusitaniadalen Member of the Vikinghøgda Formation.
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.
Agecephalichthys is an extinct genus of prehistoric freshwater bony fish that lived during the Anisian age in what is now New South Wales, Australia.
Parasemionotus is an extinct genus of prehistoric bony fish that lived in the Induan age of the Early Triassic epoch in what is now Madagascar. It is the name giving genus of the family Parasemionotidae and the order Parasemionotiformes.
Mylacanthus is an extinct genus of prehistoric coelacanth lobe-finned fish that lived during the Smithian age of the Early Triassic epoch in what is now Svalbard.
Scleracanthus is an extinct genus of prehistoric coelacanth lobe-finned fish. It lived during the Early Triassic epoch in what is now Spitsbergen, Svalbard.
Boreolepis is an extinct genus of prehistoric bony fish that lived during the Wuchiapingian age in what is now Clavering Island, Greenland, and Vologda Oblast, Russia.
Boreosomus is an extinct genus of Triassic ray-finned fish. It was first described from the Arctic island of Spitsbergen, but was later also discovered in other parts of the world. The type species is Boreosomus arcticus.
Corunegenys is an extinct genus of prehistoric bony fish that lived during the Late Triassic epoch in what is now New South Wales, Australia.
Colobodus is an extinct genus of Triassic bony fish of the family Colobodontidae and order Perleidiformes. Fossils have been found in Europe and China. It could reach body lengths of about 70 cm.
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.
Uydenia is an extinct genus of prehistoric bony fish from the Cisuralian of Kazakhstan.
Sargodon is an extinct genus of neopterygian ray-finned fish that lived during the Middle and Late Triassic epochs in what is now Europe.
Gyrolepis is an extinct genus of prehistoric ray-finned fish from the Middle-Late Triassic epochs in what is now Europe. It is known both from complete specimens and isolated skeletal elements, such as scales or teeth.
Prohalecites is an extinct genus of ray-finned fish from the Ladinian and possibly Carnian (Triassic) of Italy. It is the oldest known teleosteomorph, a group that includes extant teleosts and their close fossil relatives.
Ptycholepiformes are an extinct order of prehistoric ray-finned fish that existed during the Triassic period and the Early Jurassic epoch. The order includes the genera Acrorhabdus, Ardoreosomus, Boreosomus, Chungkingichthys, Ptycholepis, and Yuchoulepis. Although several families have been proposed, some studies place all these genera in the same family, Ptycholepididae.
Ardoreosomus is an extinct genus of ray-finned fish. It was described from the Induan aged Candelaria Formation of Nevada, United States, which was located near the equator during the Early Triassic epoch. It contains only one species, A. occidentalis (monotypy).
Parasemionotiformes is an extinct order of neopterygian ray-finned fish that existed globally during the Triassic period. It comprises the families Parasemionotidae and Promecosominidae. Many of the included genera are monotypic and most species lived during the Early Triassic epoch.
Turseodus is an extinct genus of ray-finned fish found in Late Triassic freshwater sediments of the United States. Two species have been described, T. acutus from the Lockatong Formation of Pennsylvania, and T. dolorensis from the Chinle Formation of Colorado.
