The Sipuncula or Sipunculida is a class containing about 162 species of unsegmented marine annelid worms. The name Sipuncula is from the genus name Sipunculus, and comes from the Latin siphunculus meaning a "small tube".
Polychaeta is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm and the sandworm or clam worm Alitta.
Monte Bolca is a lagerstätte near Verona, Italy that was one of the first fossil sites with high quality preservation known to Europeans, and is still an important source of fossils from the Eocene.
A scolecodont is the jaw of a polychaete annelid, a common type of fossil-producing segmented worm useful in invertebrate paleontology. Scolecodonts are common and diverse microfossils, which range from the Cambrian period to the present. They diversified profusely in the Ordovician, and are most common in the Ordovician, Silurian and Devonian marine deposits of the Paleozoic era.
The Gempylidae are a family of perciform fishes commonly known as snake mackerels or escolars. The family includes about 25 species.
Frogfishes are any member of the anglerfish family Antennariidae, of the order Lophiiformes. Antennariids are known as anglerfish in Australia, where the term "frogfish" refers to members of the unrelated family Batrachoididae. Frogfishes are found in almost all tropical and subtropical oceans and seas around the world, the primary exception being the Mediterranean Sea.
Odontogriphus is a genus of soft-bodied animals known from middle Cambrian Lagerstätte. Reaching as much as 12.5 centimetres (4.9 in) in length, Odontogriphus is a flat, oval bilaterian which apparently had a single muscular foot, and a "shell" on its back that was moderately rigid but of a material unsuited to fossilization.
Mene rhombea is an extinct perciform fish belonging to the family Menidae. During the Middle Eocene, about 48 to 40 mya, these fishes lived in the Tethys Ocean, a large tropical sea in the area corresponding to the current Mediterranean. This ocean was extended between the continents of Gondwana and Laurasia. At this time, where Monte Bolca is today, M. rhombea, and its relative, M. oblonga, lived in a tropical lagoon.
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.
Bajaichthys elegans is an extinct Lutetian zeid from the Monte Bolca Lagerstätten.
Euzaphlegidae is a family of extinct escolar-like fish closely related to the snake mackerels. Fossils of euzaphlegids are found from Paleocene to Late Miocene-aged marine strata of Europe, the Caucasus Mountains, India, Iran, Turkmenistan, Italy, and Southern California.
Eozanclus brevirostris is an extinct relative of the Moorish idol that lived during the late Ypresian epoch of the Eocene in what is now Monte Bolca, northern Italy. It differs from its living relative by having a much shorter snout.
Sparnodus is an extinct genus of prehistoric perciform fish in the family Sparidae. Species of this genus were nektonic carnivore. These fishes lived in the Cenozoic Era, in Oligocene and Paleocene.
This list of fossil fish species is a list of taxa of fish that have been described during the year 2012. The list only includes taxa at the level of genus or species.
The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments.
Blochius longirostris is a species of prehistoric fish belonging to the family Blochiidae. This fish lived in the middle Eocene and its fossils have been found exclusively in the well-known Monte Bolca (Italy).
Giovanni Serafino Volta (1764–1842) was an Italian priest, naturalist, and palaeontologist, best known for his studies of fossil fish from Monte Bolca.
Flabelligeridae is a family of polychaete worms, known as the 'cage worms', notable for their cephalic cage: the chaetae of the first chaetigers form a fan-like arrangement surrounding the eversible head.
