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.
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.
Bolcanguilla is an extinct genus of prehistoric marine eel that lived during the early division of the Eocene epoch. It contains a single species, B. brachycephala from the Monte Bolca site of Italy. Its exact taxonomic affinities within the Anguilliformes remain uncertain.
Ductor is an extinct genus of prehistoric marine ray-finned fish that lived during the early Eocene. It contains a single species, D. vestenae, known from the famous Monte Bolca site of Italy. It is the only member of the family Ductoridae. It is the earliest representative of the suborder Echeneoidei, and is thought to be most closely related to cobias and dolphinfish.
Acanthonemus is an extinct genus of prehistoric marine ray-finned fish that lived from the early Eocene. It contains a single species, A. subaureus, known from the famous Monte Bolca site in Italy. It is the only genus in the extinct family Acanthonemidae.

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.
Sparnodus is an extinct genus of prehistoric perciform fish in the family Sparidae. Species of this genus were nektonic carnivores. These fishes lived in the Cenozoic Era, in the Oligocene and Paleocene.

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 Eocene-aged Monte Bolca fossil site near Verona, Italy was one of the first lagerstatte to be discovered to science, and still has one of the most prominent vertebrate faunas of all Cenozoic lagerstatte. It has the highest fish diversity of all known Cenozoic fossil sites, with many fossils having extremely detailed preservation. In addition, a very high diversity of marine invertebrates & land plants and a small number of land vertebrates are also known.
