Berycopsis is an extinct genus of marine ray-finned fish from the Late Cretaceous period. Fossils are known from England, Germany, and Lebanon. A potential specimen is known from the Czech Republic.
Caproberyx is an extinct genus of marine acanthomorph ray-finned fish, possibly a holocentrid, from the Late Cretaceous.
Bathysoma is an extinct genus of marine lampriform ray-finned fish from the early-mid Paleocene. It contains a single species, B. lutkeni from Sweden. Its fossils are common in exposures of the Danian København Limestone Formation at Limhamns kalkbrott, one of the largest quarries in northern Europe. A single specimen is also known from an erratic boulder from the Selandian Lellinge Greensand Formation of southern Sweden.
Allothrissops is an extinct genus of marine ray-finned fish in the family Ichthyodectiformes, or bulldog fish. It is known from the Late Jurassic of Germany, where it has been found in the famous Solnhofen Limestone.
Archaeozeus is an extinct genus of marine ray-finned fish from the Ypresian epoch Fur Formation of Denmark. It contains a single species, A. skamolensis, and is the only member of the family Archaeozeidae. It is considered the most basal member of the order Zeiformes.
Aulopopsis is an extinct genus of prehistoric marine ray-finned fish that lived during the lower Eocene. It is considered a relative of lizardfish in the order Aulopiformes, but its exact taxonomic placement is uncertain. Some authorities place it with the Aulopidae, while others place it with the Giganturoidae.
Aulolepis is an extinct genus of prehistoric marine ray-finned fish that lived during the upper Cenomanian and early Turonian. It contains a single species, A. typus from the Chalk Group of the United Kingdom.
Aipichthyoides is an extinct genus of prehistoric marine bony fish that lived during the lower Cenomanian in what is now the West Bank. Formerly classified in the Polymixiiformes, it is now thought to be a distant relative of oarfish and opahs.
Aphanepygus is an extinct genus of prehistoric marine holostean ray-finned fish that lived during the upper Cenomanian. It inhabited the former Tethys Ocean, with remains known from Lebanon and Croatia. Its exact affinities are uncertain, although it is usually recovered as a relative of the macrosemiids. However, other authorities recover it in the Ionoscopiformes.
Adriacentrus is an extinct genus of prehistoric marine bony fish that lived in the Turonian in what is now Croatia. It contains a single species, A. crnolataci. Formerly considered a beryciform fish, it is now known to be more closely related to the squirrelfish (Holocentridae).
Berycopsia is an extinct genus of beardfish that lived during the Turonian stage of the Late Cretaceous. It contains a single species, B. inopinnata, that inhabited marine habitats of the Tethys Sea around what is now Croatia.
Aphnelepis is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Late Jurassic epoch. It contains a single species, A. australis, from the Talbragar River beds of New South Wales, Australia.
Africentrum is an extinct genus of prehistoric soldierfish that lived during the Upper Miocene subepoch of what is now Malta. It contains a single species, A. melitense. It has been either recovered as the sister genus to Myripristis or in a polytomy with all the other genera in the subfamily.
Berybolcensis is an extinct genus of prehistoric marine ray-finned fish that lived in the early Eocene. It contains a single species, B. leptacanthus, from the Monte Bolca lagerstatten of Italy. It was a member of the Holocentridae, making it related to modern squirrelfish and soldierfish, although it was more basal than either, and is thought to have diverged from their common ancestor around the Cretaceous-Paleogene boundary. It is thought to be related to Tenuicentrum, another basal holocentrid from the same formation.
Asialepidotus is an extinct genus of prehistoric marine ray-finned fish that lived during the Ladinian stage of the Middle Triassic epoch. It contains a single species, A. shingyiensis, from Guizhou, China.
Besania is an extinct genus of prehistoric marine ray-finned 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.
Anaethalion is an extinct genus of prehistoric marine and freshwater ray-finned fish related to modern tarpons and ladyfish. It is known from the Late Jurassic to the Early Cretaceous of Europe and northeasterrn Asia, roughly encompassing the Tethys Ocean.
Brannerion is an extinct genus of prehistoric marine bonefish. Fossils of the genus were found in the Romualdo Formation of the Santana Group, Araripe Basin, northeastern Brazil. It is considered a basal member of the Albuliformes.
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.
Caeus is an extinct genus of prehistoric marine ray-finned fish, closely related to the modern milkfish. It contains a single species, C. leopoldi from the Early Cretaceous of the Pietraroja Plattenkalk, Italy. It is one of the largest teleosts known from the Pietraroja formation, and is known by only a single specimen.
