Eophycis is an extinct genus of prehistoric morid gadiform fish that lived during the early Oligocene epoch in the Paratethys Sea, where it is known from both the eastern and western regions. It represents the oldest fossil record of the Moridae.
Balistomorphus is an extinct genus of prehistoric triggerfish during the early Oligocene epoch in what is now Canton Glarus, Switzerland, where fossils are known from the Matt Formation. It inhabited the marine environment of the Paratethys.
Dorsolepis is an extinct genus of prehistoric marine ray-finned fish that lived during the early Anisian age in what is now France (Alsace) and Germany (Baden-Württemberg). Fossils were found in the Grès à Voltzia in Alsace and in the Buntsandstein in Baden-Württemberg.
Bregmacerina is an extinct genus of prehistoric marine ray-finned fish, most likely a codlet, that lived during the early part of the Miocene epoch. It contains a single species, B. antiqua, from the Burdigalian Sakaraul Horizon Formation of North Caucasus, Russia.
Acentrophorus is an extinct genus of prehistoric freshwater and marine ray-finned fish from the Roadian to the Wuchiapingian of England, Germany (Kupferschiefer), Italy and Russia. There may also be a Triassic occurrence in Australia.
Caprovesposus is an extinct, prehistoric surgeonfish that inhabited the Paratethys Sea during the Oligocene. It is known from a single species, C. parvus, from what is now the North Caucasus, Russia. Potential specimens are known from the Miocene of Egypt, but these are poorly preserved and this attribution is uncertain.
Seriola is a genus of ray-finned fish, with many species commonly known as amberjacks. Nine extant species are currently recognized, although these were formerly split into many more. Also, several species are currently placed in several other genera of the Carangidae that were originally described under Seriola. They are a large, carnivorous finfish popularly known for the firm texture and rich flavour of their flesh, which make them an ideal fish for aquaculture. Because specimens caught can weigh up to 100 kg (220 lb), and are powerful swimmers and hunters, they are also highly prized by sport fisherman.
Proscinetes is an extinct genus of prehistoric pycnodontiform ray-finned fish from the Jurassic.
Eurynotoides is an extinct genus of prehistoric bony fish in the family Eurynotoididae of the order Eurynotoidiformes.
Korutichthys is an extinct genus of prehistoric marine bony fish that lived during the Lopingian epoch in what is now Krasnoyarsk Krai, Russia. It was first referred to the family Amblypteridae, a view that was later questioned.
Macrosemius is an extinct genus of macrosemiid fish known from the Late Jurassic of Germany.
Saurorhynchus is an extinct genus of carnivorous bony fish that lived during the Early and Middle Jurassic epochs. Fossils have been found in Europe and North America (Canada). It is commonly found in pelagic and lagoonal deposits, but mostly marine. Largest specimens can grow up to 1.9 metres (6.2 ft).
Palimphyes is an extinct genus of marine ray-finned fish known from the Paleogene period. It was a euzaphlegid, an extinct family of scombroid fish related to the escolars and snake mackerels.
Peipiaosteus is an extinct genus of prehistoric chondrostean ray-finned fish. Its fossils are found in the Early Cretaceous Jiufotang Formation, Pani Lake, Liaoning Province, China.
