Canobius is an extinct genus of marine ray-finned fish that lived in the early Carboniferous period (Viséan) of Glencartholm, Scotland.
Oxyaena is an extinct genus of placental mammals from extinct subfamily Oxyaeninae within extinct family Oxyaenidae, that lived in Europe, Asia and North America during the early Eocene.
Pteronisculus is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic and Middle Triassic epochs of the Triassic period worldwide.
Eocottus is an extinct genus of prehistoric marine ray-finned fish that lived during the early Eocene. It contains a single species, E. veronensis from the Monte Bolca site of Italy.
Eoholocentrum is an extinct genus of prehistoric marine ray-finned fish that lived during the early Eocene. It contains a single species, E. macrocephalum, known from the Early Eocene of Monte Bolca, Italy. It resembled and was closely related to modern squirrelfishes and soldierfishes, and appears to have been more closely related to squirrelfishes. It can be considered a basal or stem member of the Holocentrinae.
Mylomyrus is an extinct genus of prehistoric bony fish that lived from the early to middle Eocene Epoch.
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.
Crenilepis is an extinct genus of prehistoric marine ray-finned fish that lived in the seas of present-day Europe during the Middle Triassic epoch. It contains a single species, C. sandbergi from the Anisian of Germany, Spain, and the Besano Formation of the Swiss-Italian border.
Caruichthys is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Early Triassic epoch. It contains a single species, Caruichthys ornatus, known from what is now South Africa. It is known from a single specimen, which was collected from the middle Beaufort Series of Doorn River.
Bradyurus is an extinct genus of marine ray-finned fish that lived during the Eocene. It contains two species, both known from the Ypresian-aged Monte Bolca site of Italy.
Eolactoria is an extinct genus of highly unusual prehistoric boxfish from the Eocene. It contains a single species, E. sorbinii from the Ypresian-aged Monte Bolca site in Italy.
Archaephippus is an extinct genus of prehistoric spadefish that lived from the early Eocene. It contains a single species, A. asper, known from Italy. Several exquisitely preserved fossils have been found from the Monte Bolca lagerstatten. Some juvenile specimens preserve the vertical striped coloration that they would have likely had in life.
Eoplatax is an extinct genus of prehistoric spadefish that lived during the Early Eocene. It contains a single species, E. papilio, from the Ypresian-aged Monte Bolca site of Italy. As its name suggests are closely allied to the extant genus, Platax, more commonly known as "batfish."
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.
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.
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.
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.
Eolates is an extinct genus of prehistoric lates perch from the Paleogene of Europe. It contains three species, two marine and one freshwater, known from the early-middle Eocene and Late Oligocene.
Eopeyeria is an extinct genus of marine catfish known from the Late Eocene. It contains a single species, E. aegyptiaca from the Qasr el-Sagha Formation of Egypt. It was initially placed in Ariopsis before being placed into its own genus, but is still thought to be a member of Ariidae.
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.
