Plectocretacicus is an extinct genus of prehistoric ray-finned fish that lived during the lower Cenomanian. [1] It contains a single species, P. clarae. Plectocretacicus is the earliest known member of the order Tetraodontiformes.
Livoniana is a genus of prehistoric lobe-finned fish which lived during the Devonian period.
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.
Eubiodectes is an extinct genus of prehistoric bony fish that lived during the Cenomanian.
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.
Agecephalichthys is an extinct genus of prehistoric freshwater bony fish that lived during the Anisian age in what is now New South Wales, Australia.
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.
Garnbergia is an extinct genus of prehistoric bony fish that lived during the Anisian stage of the Middle Triassic epoch.
Ganopristodus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish from the Devonian.
Euporosteus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Iowadipterus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Paraceratodus is an extinct genus of prehistoric lungfish. Only one species, P. germaini, is known from the latest Permian or earliest Triassic period of Madagascar. Phylogenetic evidence supports it being the most basal member of the suborder Ceratodontoidei, which contains modern lungfish, and as with the rest of the order it likely diverged during the late Carboniferous.
Boreolepis is an extinct genus of prehistoric bony fish that lived during the Wuchiapingian age in what is now Clavering Island, Greenland, and Vologda Oblast, Russia.
Cretatriacanthus is an extinct genus of prehistoric ray-finned fish. It contains a single species, C. guidotti.
Dialipina is an extinct genus of prehistoric, marine osteichthyan. It was initially thought to be an early, basal actinopterygian, but recent phylogenetic analyses suggest that it may instead be a stem-osteichthyan.
Sundayichthys is an extinct genus of prehistoric bony fish that lived during the Carboniferous period in what is now South Africa. Fossils were recovered from the Upper Witteberg Series.
Egertonia is an extinct genus of prehistoric bony fish. The earliest occurrences of the genus in the fossil record are from the Late Cretaceous of Madagascar and India.
Korutichthys is an extinct genus of prehistoric marine bony fish that lived during the Lopingian epoch in what is now Krasnoyarsk Krai, Russia. It was first referred to the family Amblypteridae, a view that was later questioned.
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.
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.
Morrolepis is an extinct genus of prehistoric coccolepidid "palaeoniscoid" ray-finned fish that lived during the Late Jurassic and earliest Cretaceous epochs in Europe, Asia and North America.
