Eugnathides is an extinct genus of prehistoric bony fish that lived from the Oxfordian to the early Tithonian stage of the Late Jurassic epoch. [1] Eugnathides may have been similar to Sphaerodontes (from the Late Jurassic of Cuba). [2]
Bobbichthys is an extinct genus of marine ray-finned fish that lived in what is now Chile during the Oxfordian stage of the Late Jurassic epoch. It was a member of the Varasichthyidae, a family of potentially crossognathiform fish.
Chongichthys is an extinct genus of marine ray-finned fish that lived during the Oxfordian stage of the Late Jurassic epoch. It contains one species, C. dentatus from the Quebrada El Profeta of Chile. It is named after Chilean geologist Guillermo Chong.
Hungkiichthys is an extinct genus of prehistoric bony fish that lived during the Late Jurassic epoch.
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.
Saurostomus is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic epoch.
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.
Songanella is an extinct genus of prehistoric bony fish that lived during the early Tithonian stage of the Late Jurassic epoch.
Leptolepides is an extinct genus of prehistoric ray-finned fish that lived during the early Tithonian stage of the Late Jurassic epoch.
Eichstaettia is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic epoch.
Liodesmus is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic epoch.
Asthenocormus is an extinct genus of large marine pachycormiform ray-finned fish. It contains a single species, A. titanius. A member of the edentulous suspension feeding clade within the Pachycormiformes, fossils have been found in the Upper Jurassic plattenkalks of Bavaria, Germany.
Eurycormus is an extinct genus of prehistoric bony fish that lived from the Callovian stage of the Middle Jurassic epoch to the early Tithonian stage of the Late Jurassic epoch.
Proleptolepis is an extinct genus of ray-finned fish belonging to the family Leptolepidae.
Proscinetes is an extinct genus of prehistoric pycnodontiform ray-finned fish from the Jurassic.
Eomesodon is an extinct genus of prehistoric ray-finned fish. It lived during the Late Triassic and Jurassic.
Macrosemius is an extinct genus of macrosemiid fish known from the Late Jurassic of 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.
Saurorhynchus is an extinct genus of carnivorous bony fish that lived during the Early and Middle Jurassic epochs. Fossils have been found in Europe and North America (Canada). It is commonly found in pelagic and lagoonal deposits, but mostly marine. Largest specimens can grow up to 1.9 metres (6.2 ft).
Plesiococcolepis is an extinct genus of prehistoric ray-finned fish. It belongs to the family Coccolepididae and is known from the Early Jurassic of Lingling-Hengyang, Hunan, China.
