Trigonodon is an extinct genus of prehistoric ray-finned fish. Species include Trigonodon jugleri. [1]
Temnodontosaurus is an extinct genus of ichthyosaur from the Early Jurassic period. They lived between 200 and 175 million years ago (Hettangian-Toarcian) in what is now Western Europe and possibly Chile. It lived in the deeper areas of the open ocean. University of Bristol paleontologist Jeremy Martin described the genus Temnodontosaurus as "one of the most ecologically disparate genera of ichthyosaurs," although the number of valid Temnodontosaurus species has varied over the years.
Notobrachyops is a genus of brachyopid temnospondyl amphibian. It is known from a skull roof impression found in the Ashfield Shale of Mortdale, New South Wales, Australia. The Ashfield Shale has also yielded a shark species, a lungfish species, six species of paleoniscid fish, a species of holostean fish, a subholostean fish, and the labyrinthodont amphibian Paracyclotosaurus davidi.
Elonichthys is an extinct genus of prehistoric bony fish. The genus is represented by several species from Carboniferous and Permian of Europe, Greenland, South Africa, and North America.
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.
Crenilepis is an extinct genus of prehistoric bony fish that lived in the seas of present-day Europe during the Anisian stage of the Middle Triassic epoch.
Caruichthys is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch in what is now South Africa. It is known from a single specimen, which was collected from the middle Beaufort Series of Doorn River.
Aeduella is an extinct genus of prehistoric freshwater bony fish that lived during the Gzhelian and Asselian-Sakmarian ages in what is now France, Germany, Switzerland and the Czech Republik.
Bobasatrania is an extinct genus of prehistoric bony fish that survived the Permian-Triassic extinction event. Fossils of Bobasatrania were found in beds of Changhsingian to Ladinian age. It was most speciose during the Early Triassic.
Colobodus is an extinct genus of Triassic bony fish of the family Colobodontidae and order Perleidiformes. Fossils have been found in Europe and China. It could reach body lengths of about 70 cm.
Coccolepis is an extinct genus of prehistoric ray-finned fish in the family Coccolepididae. Originally including most species within the family, it is now restricted to two species from the Late Jurassic Solnhofen Limestone of Germany. The holotype of C. bucklandi, designated and described by Louis Agassiz, was thought to be lost but was later rediscovered in Neuchâtel.
Psilichthys is an extinct genus of prehistoric bony fish from Eumeralla Formation, the Lower Cretaceous epoch of what is now Victoria, Australia, known from single species P. selwyni. This is the first Mesozoic fossil vertebrate named from Victoria.
Igornella is an extinct genus of prehistoric bony fish that lived during the Gzhelian (Stephanian) to Asselian ages in what is now France (Burgundy).
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.
Ophiopsis is an extinct genus of prehistoric ray-finned fish belonging to the family Ophiopsidae. Specimens are known from the Tithonian-age Solnhofen Formation of Bavaria, 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).
Phanerosteon is an extinct genus of prehistoric bony fish from the Carboniferous period. The type species, P. mirabile, was recovered from the Calciferous sandstone series (Pennsylvanian), Scotland. A second species, P. phonax was described from the Serpukhovian aged Bear Gulch Limestone lagerstätte in Montana, United States.
Joffrichthys is a genus of prehistoric bony fish. This North American genus includes three species, J. symmetropterus, J. tanyourus and J. triangulpterus. The last species is known from the Paleocene of the Sentinel Butte Formation of North Dakota.
Tarasiiformes is an extinct order of prehistoric ray-finned fish.
Dorypterus is a small, extinct genus of prehistoric ray-finned bony fish. It lived during the Wuchiapingian stage of the late Permian epoch in what is now Germany (Kupferschiefer) and England. It is a hypsisomatic bobasatraniiform with a high dorsal fin. Due to anatomical differences with other bobasatraniiforms, such as the presence of pelvic fins and the reduced scale cover, Dorypterus is placed in its own monotypic family, Dorypteridae.
