Monte Bolca is an Early Eocene-aged geologic site located near Verona, Italy. A Konservat-Lagerstätte, it contains an extremely well-preserved and diverse marine biota, including the most diverse fish fauna of any Cenozoic fossil site, as well as many of the earliest fossil occurrences of modern marine fish groups. It was one of the first fossil sites with high quality preservation known to Europeans, with studies of its biota dating back to the 18th century and earlier, and is still an important source of fossils.
Galeorhinus is a genus of houndshark containing one extant species, the widespread but highly threatened school shark, and several extinct species dating back to the Late Cretaceous (Cenomanian).
Pycnodus is an extinct genus of ray-finned fish from the Eocene period. It is wastebasket taxon, although many fossils from Jurassic or Cretaceous are assigned to this genus, only Eocene species, P. apodus is valid. As its name suggests, it is the type genus of Pycnodontiformes.
Urolophus is a genus of round rays mostly native to the western Pacific Ocean and the Indian Ocean, though one species occurs in the Pacific waters of the Mexican coast. Müller and Henle erected Urolophus in an 1837 issue of Bericht Akademie der Wissenschaften zu Berlin. The name is derived from the Greek oura, meaning "tail", and lophos, meaning "crest". In Urolophus, the outer rims of the nostrils are not enlarged into lobes, but may form a small knob at the back.
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.
Aulorhamphus is an extinct genus of prehistoric marine ray-finned fish that lived from the early to middle Eocene. It contains four species known from the Early Eocene of Italy and the Middle Eocene of Russia. It was an aulorhamphid, an extinct family of syngnathiform fishes.
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.
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.
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."
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.
Platinx is an extinct genus of marine ray-finned fish that inhabited the northern Tethys Ocean during the early to middle Eocene. It was the last surviving member of the ancient order Crossognathiformes, which was a dominant and successful group throughout the preceding Mesozoic era.
The Platyrhinidae are a family of rays, commonly known as thornbacks due to their dorsal rows of large thorns. They resemble guitarfishes in shape. Though traditionally classified with stingrays, molecular evidence suggests they are more closely related to electric rays in the order Torpediniformes.
Eogaleus is an extinct genus of requiem shark from the Eocene epoch. It contains a single species, E. bolcensis. It is known from multiple articulated individuals from the Bolca Konservat−Lagerstätte of the Ypresian of Italy. It was a shallow water species.
Titanonarke is an extinct genus of large electric rays known from the Ypresian age of the Eocene epoch. It currently contains two species from the Bolca Lagerstatte of Italy, T. molini and T. megapterygia. The exceptional preservation of multiple entire individuals has allowed a detailed reconstruction of their lives. Specimens of both species have been found with various ontogenetic stages and with parasitic isopods preserved. One specimen contains a fossilized embryo, showing this species to be viviparous. This species seems to prefer shallow water habitats associated with coral reefs, not unlike modern relatives. Stomach contents reveal a diet which included an extinct large benthic foraminifera genus, Alveolina.
Pseudorhina is an extinct genus of squatiniform shark closely related to modern angelsharks. Fossils are known from the Late Jurassic and Early Cretaceous of Europe.
Lessiniabatis is an extinct genus of highly unusual stingray from the Early Eocene of Italy. It contains a single species, L. aenigmatica. It is known from three specimens, one nearly complete, from the famous Monte Bolca lagerstätte.
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.
Sphyraena bolcensis is an extinct species of prehistoric barracuda known from the Eocene. It is known from the late Ypresian-aged Monte Bolca site of Italy.
Galeorhinus cuvieri is an extinct species of houndshark known from the Early Eocene-aged Monte Bolca site of Italy. It was a close relative of the modern tope or school shark, which it is highly morphologically similar to.
