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.
Neopholidophoropsis is an extinct genus of stem-teleost ray-finned fish that lived in what is now Germany during the Aptian stage of the Early Cretaceous epoch. It contains one species, Neopholidophoropsis serrata.
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.
Antofagastaichthys 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, A. mandibularis, which is known from several fragmentary specimens discovered in the El Profeta Formation of Antofagasta Province.
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.
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.
Asthenocormus is an extinct genus of pachycormiform ray-finned fish. A member of the edentulous suspension feeding clade within the Pachycormiformes, fossils have been found in the Upper Jurassic plattenkalks of Bavaria, Germany.
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.
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.
Pholidophoristion is an extinct genus of stem-teleost ray-finned fish that lived in what is now Europe from the Late Jurassic to the Early Cretaceous.
Pholidorhynchodon is an extinct genus of ray-finned fish that lived in the Triassic. Its fossils have been found in Italy, in the Zorzino Limestone Formation in Cene.
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.
Crossognathiformes is an extinct order of ray-finned fish that lived from the Late Jurassic to the Eocene. Its phylogenetic placement is disputed; some authors have recovered it as part of the teleost stem group, while others place it in a basal position within crown group Teleostei.
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.
Goulmimichthys is an extinct genus of ray-finned fishes in the family Pachyrhizodontidae. The genus, first described by Cavin in 1995, is known from various Turonian age formations. The type species G. arambourgi from the Akrabou Formation in the El Rachidia Province of Morocco, and other fossils described are G. gasparini of the La Frontera Formation, Colombia, and G. roberti from the Agua Nueva Formation of Mexico.
