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.
Daedalichthys is an extinct genus of prehistoric ray finned, bony fish that lived during the Early Triassic epoch.
Pholidophoretes is an extinct genus of prehistoric ray-finned fish that lived during the Carnian stage of the Late Triassic epoch.
Luganoia is an extinct genus of prehistoric bony fish that lived during the Anisian and Ladinian ages of the Middle Triassic epoch. Fossils were recovered from the Besano Formation of Monte San Giorgio and Besano area and from the Zhuganpo Member of Guizhou, South China. It was also reported from the Ladinian of Spain.
Besania is an extinct genus of prehistoric bony fish that lived during the Anisian and Ladinian ages of the Middle Triassic epoch in what is now southern/southeastern Switzerland and northern Italy. Fossils were recovered from the Besano Formation of Monte San Giorgio area and the Prosanto Formation of canton Graubünden, Switzerland.
Habroichthys is an extinct genus of prehistoric bony fish that lived during the early Ladinian stage of the Middle Triassic epoch, 242 to 232 million years ago. It has been found in Austria, China, Italy, Slovenia, and Switzerland. It was a small fish measuring 26 cm (10 in) long.
Scleracanthus is an extinct genus of prehistoric coelacanth lobe-finned fish. It lived during the Early Triassic epoch in what is now Spitsbergen, Svalbard.
Acentrophorus is an extinct genus of prehistoric ray-finned fish from the Wuchiapingian of England and Germany (Kupferschiefer). There may also be a Triassic occurrence in Australia.
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.
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.
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.
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.
Hemicalypterus is an extinct genus of prehistoric ray-finned fish that lived during the late Triassic period. It contains a single species, Hemicalypterus weiri. Fossils have been collected in the southwestern United States, including Utah and New Mexico. Hemicalypterus belonged to the family Dapediidae, and like other members of its family, it was a deep-bodied fish with a covering of thick ganoid scales. It differed from other dapediids in lacking scales on the posterior part of the body, and in possessing unusual, multicuspid teeth. These teeth were similar to those of modern-day herbivorous fish, which indicates that Hemicalypterus may have been a herbivore as well.
Ptycholepis is an extinct genus of prehistoric ray-finned fish having the head and opercular bones ornamented with ridges of ganoin, minute teeth, and thick scales.
Meridensia is an extinct genus of prehistoric ray-finned fish that lived during the Anisian and Ladinian ages of the Middle Triassic epoch in what is now southern Switzerland and northern Italy. Fossils were recovered from the Besano Formation of Monte San Giorgio and Besano area at the Swiss-Italian boundary.
Placopleurus is an extinct genus of prehistoric ray-finned fish from the Middle Triassic epoch of Italy, Slovenia, and Switzerland.
Dorypterus is a small, extinct genus of prehistoric ray-finned bony fish. It lived during the Wuchiapingian stage of the late Permian epoch in what is now Germany (Kupferschiefer) and England. It is a hypsisomatic bobasatraniiform with a high dorsal fin. Due to anatomical differences with other bobasatraniiforms, such as the presence of pelvic fins and the reduced scale cover, Dorypterus is placed in its own monotypic family, Dorypteridae.
Acropholis is an extinct genus of prehistoric marine bony fish that lived during the Wuchiapingian age in what is now Greenland and Hesse (Germany).
