Ophiopsis is an extinct genus of prehistoric ray-finned fish belonging to the family Ophiopsidae. Specimens are known from the Tithonian-age Solnhofen Formation of Bavaria, Germany.
The type species, Ophiopsis muensteri, was previously placed in Furo by several authors who mistakenly considered Ophiopsiella procera the Ophiopsis type species. However, Lane and Ebert (2015) noted that Ophiopsis originally included O. muensteri only when first erected by Agassiz (1834), so they re-assigned procera and some Ophiopsis species to the new genus Ophiopsiella.

Pterodactylus is an extinct genus of pterosaurs. It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile.
The operculum is a series of bones found in bony fish and chimaeras that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding.
Pholidophorus is an extinct genus of stem-teleost fish from the Triassic period of Africa, Europe, and South America.
Ichthyodectiformes is an extinct order of marine stem-teleost ray-finned fish. The order is named after the genus Ichthyodectes, established by Edward Drinker Cope in 1870. Ichthyodectiforms are usually considered to be some of the closest relatives of the teleost crown group.
Megalichthys is a genus of prehistoric lobe-finned fish which lived during the Carboniferous period. It is the type genus of the family Megalichthyidae. The type species is M. hibberti. The species M. mullisoni is known from the Catskill Formation of Pennsylvania.
Luisiella is an extinct genus of prehistoric bony fish that lived during the Kimmeridgian stage of the Late Jurassic epoch. Fossils of the genus have been found in either the Cañadón Calcáreo Formation or Cañadón Asfalto Formation in Chubut Province, Argentina.
Metaceratodus is an extinct genus of prehistoric lungfish in the family Ceratodontidae, with an indeterminate specimen known from the Late Triassic (Norian)-aged Lissauer Breccia of Poland and more complete specimens known from the Late Cretaceous of Queensland, Australia and Argentina. The genus was named and described by Frederick Chapman in 1914.
Ptychoceratodus is an extinct genus of prehistoric sarcopterygians or lobe-finned fish originally named as a species of Ceratodus in 1837. It was a lungfish from the Mesozoic era (Triassic-Cretaceous), and the only members of the family Ptychoceratodontidae. One species, P. oldhami, was named in 2018 based on remains from the Carnian-aged Tiki Formation (India). The first named species, which is also the type species, is P. phillipsi, which was named in 1837 by Louis Agassiz as a species of Ceratodus and moved to a separate genus in 1926.
Trachymetopon is an extinct genus of prehistoric coelacanth from the Early Jurassic Posidonia Shale of Germany and the Middle Jurassic of France. Only one species has been named, Trachymetopon liassicum, described by Henning in 1951 from an almost complete specimen found in the Lower Toarcian of Ohmden in Baden-Württemberg. Another specimen is known from the same site, and two older specimens come from the Sinemurian of Holzmaden. The holotype of this species is 1.6 metres in length. A giant specimen of an undetermined species of Trachymetopon is known from the Middle Jurassic of Normandy. This specimen, composed of a 53 cm long palatoquadrate, belongs to an individual 4 metres (13 ft) in length. A study published in 2015 revealed that this coelacanth belongs to the Mawsoniidae. Trachymetopon is one of the few known mawsoniids to have been exclusively marine, while most of the other members of the group have lived in fresh and brackish waters.
Coccolepis is an extinct genus of prehistoric ray-finned fish in the family Coccolepididae. Originally including most species within the family, it is now restricted to two species from the Late Jurassic Solnhofen Limestone of Germany. The holotype of C. bucklandi, designated and described by Louis Agassiz, was thought to be lost but was later rediscovered in Neuchâtel.
Pleuropholis is an extinct genus of prehistoric ray-finned fish.
The Solnhofen Plattenkalk, a collective term of multiple Late Jurassic lithographic limestones in southeastern Germany, is famous for its well preserved fossil flora and fauna dating to the late Jurassic.
This list of fossil fishes described in 2015 is a list of new taxa of jawless vertebrates, placoderms, acanthodians, fossil cartilaginous fishes, bony fishes and other fishes of every kind that have been described during the year 2015, as well as other significant discoveries and events related to paleontology of fishes that occurred in the year 2015. The list only includes taxa at the level of genus or species.
Cladodus is an extinct genus of cartilaginous fishes in the family Cladoselachidae. As the name implies, they are a type of cladodont, primitive sharks with teeth designed to snag fish and swallow them whole, instead of sawing off chunks to swallow.
This list of fossil fishes described in 2016 is a list of new taxa of jawless vertebrates, placoderms, acanthodians, fossil cartilaginous fishes, bony fishes and other fishes of every kind that have been described during the year 2016, as well as other significant discoveries and events related to paleontology of fishes that occurred in the year 2016. The list only includes taxa at the level of genus or species.
Eichstaettisaurus is a genus of lizards from the Late Jurassic and Early Cretaceous of Germany, Spain, and Italy. With a flattened head, forward-oriented and partially symmetrical feet, and tall claws, Eichstaettisaurus bore many adaptations to a climbing lifestyle approaching those of geckoes. The type species, E. schroederi, is among the oldest and most complete members of the Squamata, being known by one specimen originating from the Tithonian-aged Solnhofen Limestone of Germany. A second species, E. gouldi, was described from another skeleton found in the Matese Mountains of Italy. Despite being very similar to E. schroederi, it lived much later, during the Albian stage. Fossils of both species show exceptional preservation due to deposition in low-oxygen marine environments.
Ophiopsiella is an extinct genus of prehistoric ray-finned fish closely related to the bowfin.
Furo is an extinct genus of ray-finned fish belonging to the order Ioniscopiformes that has been found in Europe. The type species is F. orthostomus.
Ginglymodi is a clade of ray-finned fish containing modern-day gars (Lepisosteidae) and their extinct relatives, including the family Lepidotidae and the orders Semionotiformes and Kyphosichthyiformes, and various other extinct taxa. Ginglymodi is one of the two major subgroups of the infraclass Holostei, the other one being Halecomorphi, which contains the bowfin and its fossil relatives.
Coccolepididae is an extinct family of ray-finned fish, known from the Early Jurassic to Early Cretaceous, most of which were originally referred to the type genus Coccolepis. They had a widespread distribution, being found in North and South America, Australia, Asia and Europe. They are mostly known from freshwater environments, though several were marine. They are morphologically conservative, and have poorly ossified endo and exoskeletons, which usually results in poor preservation. This makes it difficult to distinguish species. They are generally small fish, with the largest known specimens reaching a length of 210 mm. Historically, they have been classified as members of “Palaeonisciformes”, a paraphyletic grouping of all non-neopterygian fish, due to their plesiomorphic conservative morphology closely resembling those of many other groups of primitive fish. They have been suggested to be relatives of the Acipenseriformes within the Chondrostei.
