Orthocormus is an extinct genus of prehistoric pachycormiform bony fish. [1] It is known from three species found in Late Jurassic (Kimmeridgian) aged plattenkalk deposits in Bavaria, Germany. [2] 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. [3]
Leedsichthys is an extinct genus of pachycormid fish that lived in the oceans of the Middle to Late Jurassic. It is the largest ray-finned fish, and amongst the largest fish known to have ever existed.
Dapedium is an extinct genus of primitive neopterygian ray-finned fish. The first-described finding was an example of D. politum, found in the Lower Lias of Lyme Regis, on the Jurassic Coast of England. Dapedium lived in the late Triassic and Jurassic periods.
Hypsocormus is an extinct genus of pachycormid fish from the Middle to Late Jurassic of Europe. Fossils have been found in Germany, France and the UK.
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.
Luckeus is a genus of prehistoric lobe-finned fish. Luckeus belonged to the group of onychodontid fishes. It lived during the Early Devonian to Middle Devonian period in central Australia.
Pachycormiformes is an extinct order of marine ray-finned fish known from the Early Jurassic to the end of the Cretaceous. It only includes a single family, Pachycormidae. They were characterized by having serrated pectoral fins, reduced pelvic fins and a bony rostrum. Their exact relations with other fish are unclear, but they are generally though to be teleosteomorphs, more closely related to teleosts than to Holostei. Pachycormiformes are morphologically diverse, containing both tuna and swordfish-like carnivorous forms, as well as edentulous suspension-feeding forms, with the latter including the largest ray finned fish known to have existed, Leedsichthys, with an estimated maxiumum length of 16 metres.
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.
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.
Oligopleurus is an extinct genus of prehistoric bony fish that lived during the Kimmeridgian stage of the Late Jurassic epoch.
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.
Ainia is an extinct genus of prehistoric ray-finned fish that lived during the early Toarcian stage of the Early Jurassic epoch.
Ganopristodus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Iowadipterus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
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.
Prohalecites is an extinct genus of ray-finned fish from the Ladinian and possibly Carnian (Triassic) of Italy. It is the oldest known teleosteomorph, a group that includes extant teleosts and their close fossil relatives.
Ligulalepis is an extinct genus of prehistoric bony fish. Ligulalepis was first described from isolated scales found in the Taemas-Wee jasper limestones of New South Wales by Dr Hans-Peter Schultze (1968) and further material described by Burrow (1994). A nearly complete skull found in the same general location was described in Nature by Basden et al. (2000) claiming the genus was closely related to basal ray-finned fishes (Actinopterygii). In 2015 Flinders University student Benedict King found a more complete new skull of this genus which was formally described by Clement et al. (2018), showing the fish to be on the stem of all osteichthyans.
Cavenderichthys talbragarensis is a species of prehistoric bony fish found in the Talbragar Fish beds. Recently, it has been placed as a member of Orthogonikleithridae, alongside Leptolepides, Orthogonikleithrus and Waldmanichthys.

Dorsetichthys is an extinct genus of stem-teleost ray-finned fish from the Early Jurassic period of Europe.
