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.
Oreochima ellioti is an archaeomaenid ray-finned fish from Lower Jurassic-aged freshwater strata of Antarctica. Fossils come from the Lower Jurassic Carapace Formation (Pliensbachian-Toarcian) of Storm Peak, Antarctica, where a freshwater lake system once existed. O. ellioti is also notable for being one of three archaeomaenid genera found outside of Australia.
Euthynotus is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic epoch. It is generally considered the basalmost pachycormiform.
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.
Swenzia is an extinct genus of coelacanthid fish from the late Jurassic of France. It contains a single species, S. latimerae, which was originally described as Wenzia latimerae. Because the generic name Wenzia was already preoccupied by a snail, the generic name was amended to Swenzia. It is the fossil genus most closely related to the living coelacanth, Latimeria.
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.
Anaethalion is an extinct genus of prehistoric ray-finned fish.
Ascalabos is an extinct genus of ray-finned fish known from the Late Jurassic Solnhofen Limestone of Germany. It contains one species, A. voithii.
Saurorhynchus is an extinct genus of carnivorous bony fish. It is the youngest representative of the family Saurichthyidae and the order Saurichthyiformes. This family is known for its large, elongate jaws, similar to modern Belonidae. Saurichthyidae also includes the Permian genus Eosaurichthys and the Triassic genus Saurichthys.
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.
Orthogonikleithrus is a genus of extinct ray-finned fish that lived during the Late Jurassic period. It lived in lagoonal and restricted shallow subtidal zones.
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.
