Xyne is an extinct genus of prehistoric herring that lived during the Upper Miocene subepoch. [1]
There are two species described: the type species, X. grex, and a second, deeper-bodied species, X. fitgeri. Fossils are known from the Dicalite Quarry and Diatom Hill in California. [2]
Plectocretacicus is an extinct genus of prehistoric ray-finned fish that lived during the lower Cenomanian. It contains a single species, P. clarae. Plectocretacicus is the earliest known member of the order Tetraodontiformes.
Coccodus is an extinct genus of extinct pycnodontid fish that lived during the lower Cenomanian. The various species had a pair of massive, curved spines emanating from the lower sides of the head, and one curved spine on the top of its head. Unlike most pycnodontids, Coccodus species had a comparatively long body, giving the living animals a superficial resemblance to a scaly chimaera.
Judeichthys is an extinct genus of prehistoric ray-finned fish that lived during the lower Cenomanian. There is one currently known species †Judeichthys haasi which was found near Ramallah in Israel.
Elopopsis is an extinct genus of prehistoric bony fish that lived from the Cenomanian to Campanian.
Eubiodectes is an extinct genus of prehistoric bony fish that lived during the Cenomanian.
Domeykos is an extinct genus of prehistoric bony fish that lived during the Oxfordian stage of the Late Jurassic epoch.
Varasichthys is an extinct genus of prehistoric bony fish that lived during the Oxfordian stage of the Late Jurassic epoch. Fossils have been found in the Domeyko Range of Antofagasta Region, northern Chile. The genus has been compared with other South American fishes as Luisiella and Protoclupea.
Aetheolepis mirabilis is an extinct species of prehistoric archaeomaenid ray-finned fish that lived in freshwater environments in what is now Western Australia and New South Wales. A. mirabilis is easily distinguished from other archaeomaenids by having a deep, discoid-shaped body. Fossils of A. mirabilis have been found in the Talbragar River fossil beds of New South Wales and the Colalura Sandstone of Western Australia. Named first by A.S. Woodward in 1865 along with other Talbragar fish.
Absalomichthys velifer is an extinct, prehistoric manefish that lived during the Upper Miocene of what is now Southern California. Its dorsal fin was huge in comparison with living species.
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.
Austropleuropholis is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic epoch.
Parasemionotus is an extinct genus of prehistoric bony fish that lived in the Induan age of the Early Triassic epoch in what is now Madagascar. It is the name giving genus of the family Parasemionotidae. This family includes the genera Albertonia, Candelarialepis, Jacobulus, Lehmanotus, Qingshania, Stensioenotus, Suius, Thomasinotus, Watsonulus and possibly additional genera like Promecosomina. Parasemionotidae had a global distribution during the Early Triassic. Species of this family are found in Greenland, Madagascar, Canada, India, China, United States and possibly Australia.
Protoclupea is an extinct genus of prehistoric bony fish that lived from the Oxfordian to the early Tithonian stage of the Late Jurassic epoch. Fossils have been found in the Domeyko Range of Antofagasta Region, northern Chile. The genus has been compared with other South American fishes as Luisiella and Varasichthys.
Athrodon is a genus of extinct pycnodontid that lived in shallow seas in what is now England and France from the Late Jurassic until the genus extinction during the start of the late Cretaceous. The various species are very similar in splenial bone and tooth morphology to Mesodon. Otherwise, no articulated or complete specimen is known: all fossils specimens are bone fragments and disarticulated teeth.
Clidoderma is a genus of righteye flounders containing one extant species and two described fossil species from Japan.
Notelops is an extinct genus of prehistoric ray-finned fish.
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.
Plectrypops is a genus of soldierfish containing two extant species, with one species in the Indo-Pacific, and another in the western Atlantic and the Caribbean. They are red and reach a length of approximately 15 cm (6 in). Members of this genus are also known from fossil remains.
Phareodus is a genus of freshwater fish from the Paleocene to the Eocene of Australia, Europe and North and South America.
Ophiopsiella is an extinct genus of prehistoric ray-finned fish closely related to the bowfin.
