Luvarus is a genus of ray-finned fishes belonging to the family Luvaridae. It is the only extant genus in that family and its only extant species is the cosmopolitan louvar, with one fossil species known from the earliest Eocene of Turkmenistan.
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.
Eoluvarus bondei is a species of extinct bony fish once identified as being a luvar from the Fuller's Earth Ypresian formation of the Barmer District of Rajasthan, India. Later, better quality specimens were found, and E. bondei was reappraised as being a relative of the prehistoric spadefish, Exellia.
Avitoluvarus is a genus of extinct louvar that lived in the Peri-Tethys Sea during the early Paleogene. The first specimens were found from the Danata Formation Lagerstätten, of the Ypresian age of Turkmenistan, where they were originally thought to be smaller or juvenile individuals of the true louvar, Luvarus necopinatus. These specimens were later reexamined, and determined to be a separate genus comprising two species.
Ceratoichthys is an extinct genus of lookdown-like prehistoric jackfish that lived during the late Ypresian epoch, of the Early Eocene. It contains a single species, C. pinnatiformis of Monte Bolca, Italy. It and Vomeropsis are the only known members of the extinct subfamily Vomeropsinae.
Kushlukia is an extinct genus of prehistoric bony fish, closely related to the luvar, that lived during the lower Eocene. K. permira is from Eocene portion of the Danata Formation Lagerstatten, of Turkmenistan. A second, as yet undescribed species is from the Fuller's Earth formation Lagerstatten in the Barmer District, of Ypresian Rajasthan, India.
Calamostoma is an extinct relative of the ghost pipefish that lived during the early Eocene. It contains a single species, C. lesiniforme from the famous Monte Bolca site of Italy. It is one of the few known fossil ghost pipefishes. Calamostoma and the other Bolca solenostomid, Solenorhynchus, are both placed in the extinct subfamily Solenorhynchinae.
Anguilloides is an extinct genus of prehistoric marine eel that lived in the early Eocene. It contains a single species, A. branchiostegalis. Fossils are known from the famous Monte Bolca site of Italy.
Bolcyrus is an extinct genus of prehistoric marine eel that lived during the Early Eocene. It was a member of the family Congridae, which also contains modern conger eels.
Berycomorus is an extinct genus of prehistoric marine ray-finned fish that lived during the late Eocene epoch. It contains a single species, B. firdoussi, from the Pabdeh Formation of Iran.
Balistomorphus is an extinct genus of prehistoric triggerfish during the early Oligocene epoch in what is now Canton Glarus, Switzerland. It inhabited the marine environment of the Tethys Ocean.
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.
Callipteryx is an extinct genus of prehistoric marine trachiniform fish that lived during the early Eocene. It is the only known member of the extinct family Callipterygidae. It is thought to have been a relative of weeverfishes.
Carangodes is an extinct genus of prehistoric ray-finned fish that lived during the early Eocene. It contains a single species, C. bicornis, from the famous Monte Bolca site in Italy. It is the only known member of the extinct perciform family Carangodidae.
Diaphyodus is an extinct genus of prehistoric marine ray-finned fish, generally considered a drumfish, from the Late Paleocene and Eocene, and potentially to the mid-Oligocene of Europe and North America.
Dalpiazella is an extinct genus of prehistoric marine eel from the Eocene of Europe. It contains a single species, D. brevicauda, from the late Ypresian-aged Monte Bolca lagerstatten of Italy. It is though to be closely related to the sympatric genus Paranguilla, with both genera together constituting the family Paranguillidae.
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.
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.
The Danata Formation is an earliest Eocene to Middle Eocene sedimentary succession located in Turkmenistan. It is mostly famous for its fish-bearing horizons (Ichthyofauna). The formation for example crops out in the Kopet Dag mountain range in the border region of Turkmenistan and Iran. It was deposited in a far northeastern arm of the Tethys Sea.
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.
