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.
Coelacanthus is a genus of extinct marine coelacanths known from the late Permian period. It was the first genus of coelacanths described, about a century before the discovery of the extant coelacanth Latimeria. The order Coelacanthiformes is named after it.
Belonostomus is a genus of prehistoric ray-finned fish that was described by Louis Agassiz in 1844. It is a member of the order Aspidorhynchiformes, a group of fish known for their distinctive elongated rostrums.
Apateodus is a genus of prehistoric marine ray-finned fish which was described by Woodward in 1901. It was a relative of modern lizardfish and lancetfish in the order Aulopiformes, and one of a number of prominent nektonic aulopiforms of Cretaceous marine ecosystems.
Amblypterus is an extinct genus of freshwater ray-finned fish that lived during the Gzhelian and Cisuralian epoch in what is now Europe and possibly India and Argentina. Potential indeterminate records stretch as far back as the early Carboniferous.
Enchelion is an extinct genus of prehistoric marine ray-finned fish that lived during the Late Cretaceous. It contains a single species, E. montium known from the upper Cenomanian of the Haqel locality of the Sannine Formation in Lebanon. It is the only member of the family Encheliidae.
Dinopteryx is an extinct genus of prehistoric beardfish from the Late Cretaceous period. It contains a single species, D. spinosus, known from the Santonian of Lebanon. It is the only member of the extinct family Dinopterygidae, which is considered a distinct family of the Polymixiiformes. It was previously placed in the genus Hoplopteryx.
Enchelurus is an extinct genus of prehistoric marine ray-finned fish that lived during the Late Cretaceous. It contains three species, known from the Cenomanian to Campanian of Europe and the Middle East.
Eoanguilla is an extinct genus of prehistoric marine eel that lived during the early Eocene. It contains a single species, E. leptoptera from the Ypresian-aged Monte Bolca site of Italy. It is thought to have been an early marine relative of the modern freshwater eels.
Acrolepis is an extinct genus of prehistoric marine bony fish that lived from the Famennian stage of the Devonian to the early Triassic epoch. Some species from the Early Triassic of Tasmania are also ascribed to Acrolepis.
Acrognathus is an extinct genus of ray-finned fish belonging to the order Aulopiformes. Although no extensive systematic analysis has been performed, it is tentatively placed with the greeneyes in the family Chlorophthalmidae, making it the oldest representative of that family.
Boreosomus is an extinct genus of Triassic marine ray-finned fish. It was first described from the Arctic island of Spitsbergen, hence its genus name, but was later also discovered in other parts of the world. The type species is Boreosomus arcticus.
Ctenothrissa is a prehistoric genus of marine ray-finned fish in the order Ctenothrissiformes. It contains a number of species known from the Late Cretaceous of England and Lebanon.
Colobodus is an extinct genus of marine Triassic ray-finned fish of the family Colobodontidae and order Perleidiformes. Fossils have been found in Europe and China, encompassing the former Tethys Ocean. It could reach body lengths of about 70 cm.
Cylindracanthus is an extinct, enigmatic genus of marine ray-finned fish with fossils known throughout North America, Europe, Asia and Africa from the Late Cretaceous to the late Eocene, with potential Oligocene records and a possible Miocene record also known. It is exclusively known from its distinctive partial remains, which are long cylindrical bony spines that are usually considered rostrum fragments, as well as some associated teeth. These spines are abundant & widespread throughout this timespan, and are useful indicators of a nearshore marine environment, but the taxonomic identity of the fish is still highly uncertain and debated.
Eocoelopoma is an extinct genus of prehistoric scombrid fish, related to mackerels and tunas, known from the Eocene of Eurasia. It contains several species known from the Early Eocene of England and Turkmenistan.
Isurichthys is an extinct genus of prehistoric ray-finned fish, belonging to the family Ariommatidae.
Ichthyokentema ("fish-goad") is an extinct genus of stem-teleost fish that lived during the Late Jurassic. It contains one species, I. purbeckensis, which is known from the Purbeck Group of Dorset, England. I. purbeckensis was originally described as a species of Pholidophorus by William Davies in 1887, but was moved to its own genus by Arthur Smith Woodward in 1941.
Cyclopoma is an extinct genus of marine perciform fish from the Eocene. It is known from the Ypresian to the Lutetian of Europe and eastern North America.
The Matt Formation is an Early Oligocene-aged marine geological formation that outcrops in the Glarus Alps of the Canton of Glarus, Switzerland. It is most notable for its fossiliferous slates found near Engi, known as the Engi slates, Glarner Schiefer or Glarner Fischschiefer, which contain the well-preserved fossils of fishes, birds, and sea turtles. The metamorphization of the rock has led to many of the fossils appearing somewhat distorted.
