Pholidophorus is an extinct genus of stem-teleost fish. Numerous species were assigned to this genus in the past, but only the type species Pholidophorus latiusculus, from the Late Triassic of Europe, is considered to be a valid member of the genus today.
Leptolepis is an extinct genus of stem-teleost fish that lived in what is now Europe during the Jurassic period.
Gyrosteus is an extinct genus of very large ray-finned fish belonging to the family Chondrosteidae. It comprises the type species, Gyrosteus mirabilis, which lived during the early Toarcian in what is now northern Europe. A possible second species, "Gyrosteus" subdeltoideus, is known from otoliths.
Ceratodus is an extinct genus of lungfish. It has been described as a "catch all", and a "form genus" used to refer to the remains of a variety of lungfish belonging to the extinct family Ceratodontidae. Fossil evidence dates back to the Early Triassic. A wide range of fossil species from different time periods have been found around the world in places such as the United States, Argentina, Greenland, England, Germany, Egypt, Madagascar, China, and Australia. Ceratodus is believed to have become extinct sometime around the beginning of the Eocene Epoch.
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.
Bobbichthys is an extinct genus of ray-finned fish that lived in what is now Chile during the Oxfordian stage of the Late Jurassic epoch.
Domeykos is an extinct genus of ray-finned fish that lived in what is now Chile during the Oxfordian stage of the Late Jurassic epoch. It contains one species, Domeykos profetaensis.
Atacamichthys is an extinct genus of ray-finned fish. It contains one species, Atacamichthys greeni, which lived in what is now Chile during the Oxfordian stage of the Late Jurassic epoch. Atacamichthys is the only member of the family Atacamichthyidae.
Varasichthys is an extinct genus of ray-finned fish that lived during the Oxfordian stage of the Late Jurassic epoch. It contains one species, Varasichthys ariasi, fossils of which have been found in the Domeyko Range of Antofagasta Region, northern Chile. It has been placed in the family Varasichthyidae together with the genera Bobbichthys, Domeykos, Luisichthys and Protoclupea.
Chongichthys is an extinct genus of prehistoric bony fish that lived during the Oxfordian stage of the Late Jurassic epoch. Fossils of the genus have been found in the Quebrada El Profeta of Chile.
Protoclupea is an extinct genus of ray-finned fish that lived from the Oxfordian to the early Tithonian stage of the Late Jurassic epoch. It contains one species, Protoclupea chilensis, fossils of which have been found in the Domeyko Range of Antofagasta Region, northern Chile. The genus has been placed in the family Varasichthyidae together with the genera Bobbichthys, Domeykos, Luisichthys and Varasichthys.
Mioceratodus is an extinct genus of lungfish in the family Neoceratodontidae, which also contains the extant Queensland lungfish. It is known only from Oligocene and Miocene-aged sediments in Australia, although phylogenetic evidence supports it having first diverged from its closest relative, Neoceratodus, during the Late Jurassic or Early Cretaceous period.
Trachymetopon is an extinct genus of prehistoric coelacanth from the Jurassic of Europe. Fossils have been found in the Early Jurassic Posidonia Shale of Germany the Middle Jurassic Marnes de Dives of France, and probably the Late Jurassic Kimmeridge Clay of England. 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 found at the Middle Jurassic Falaises des Vaches Noires of Normandy. This specimen, composed of a 53 cm long palatoquadrate, belongs to an individual 4 metres (13 ft) in length. A basisphenoid found in a museum in Switzerland that likely originates from the same locaity probably belonged to an individual around 5 m (16 ft) long, making Trachymetopon the largest of all coelacanths alongside Mawsonia. 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.
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.
Orthocormus is an extinct genus of prehistoric pachycormiform bony fish. It is known from three species found in Late Jurassic (Kimmeridgian) aged plattenkalk deposits in Bavaria, Germany. The species "Hypsocormus" tenuirostris Woodward 1889 from the late Middle Jurassic (Callovian) Oxford Clay is not closely related to the type species of Hypsocormus, and is more closely related to Orthocormus + Protosphyraena, and thus has sometimes been referred to in open nomenclature as Orthocormus? tenuirostris. The species of Orthocormus reached over a metre in length, and are thought to have been pelagic predators.
Peipiaosteus is an extinct genus of prehistoric chondrostean ray-finned fish. Its fossils are found in the Early Cretaceous Jiufotang Formation, Pani Lake, Liaoning Province, China.
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.
This list of fossil fishes described in 2020 is a list of new taxa of jawless vertebrates, placoderms, acanthodians, fossil cartilaginous fishes, bony fishes, and other fishes of every kind that were described during the year 2020, as well as other significant discoveries and events related to paleoichthyology that occurred in 2020.
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.
Burkesuchus is an extinct genus of basal neosuchians from the Upper Jurassic (Tithonian)-aged Toqui Formation of southern Chile. The genus is currently represented by a single species B. mallingrandensis, named and described in 2021 on the basis of the holotype and additional referred specimens. Burkesuchus mallingrandensis was noticeably small being around an estimated 70 cm in length. The cranium is dorsoventrally depressed and transversely wide posteriorly and distinguished by a posteroventrally flexed wing-like squamosal. Burkesuchus was a small carnivore likely on invertebrates animals such as insects, crustaceans and may had feed on small aquatic vertebrates like fish. B. mallingrandensis did not have the ability to feed on large prey items or tear large chunks of meat like modern day crocodiles do. The holotype SQO.PV 17700, consist of a cervical neural arch, partial neurocranium, four dorsal vertebrae, right scapula, a right coracoid, right humerus, a ulna, left ischium, distal end of the right femur, one cervical and two dorsal osteoderms. The paratype SQO.PV 17701 fossil remains consist of a nearly complete right femur, two doral vertebrae and one dorsal osteoderm. The fossils was discovered in 2014 but was described as a new genus and species on July 23, 2021.
