Pronotacanthus sahelalmae is an extinct spiny eel that lived in marine environments of what is now Lebanon during the Santonian. [1]
Zeuchthiscus is a genus of prehistoric ray finned fish that lived in Australia during the Early Triassic Period. It is believed to have been a nektonic omnivore. Closely related fish had a wide distribution in the northern hemisphere.
Porolepiformes is an order of prehistoric lobe-finned fish which lived during the Devonian period. The group contains two families: Holoptychiidae and Porolepididae.
Osteolepidae is a family of prehistoric lobe-finned fishes which lived during the Devonian period.
Mesoclupea showchangensis is an extinct ichthyodectiform ray-finned fish that lived in freshwater environments in what is now China during the Early Cretaceous epoch. It differs from its sister genus, Chuhsiungichthys, primarily by having a more posteriorly-placed dorsal fin.
Chrysolepis is a genus of prehistoric lobe-finned fish that lived during the Late Devonian period.
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.
Australosomus is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic epoch.
Arctosomus is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch.
Helichthys is an extinct genus of prehistoric bony fish that lived during the Early Triassic.
Trachelacanthus is an extinct genus of prehistoric bony fish that lived during the Late Permian 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.
Dorsolepis is an extinct genus of prehistoric bony fish that lived during the Anisian stage of the Middle Triassic epoch.
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.
Kentuckia is an extinct genus of prehistoric bony fish.
Pleuropholis is an extinct genus of prehistoric ray-finned fish.
Ptycholepiformes are an extinct order of prehistoric ray-finned fish that existed during the Triassic period and the Early Jurassic epoch. The order includes the genera Acrorhabdus, Ardoreosomus, Boreosomus, Chungkingichthys, Ptycholepis, and Yuchoulepis. Although several families have been proposed, some studies place all these genera in the same family, Ptycholepididae.
Tarasiiformes is an extinct order of prehistoric ray-finned fish.
Peltopleuridae were an extinct family of prehistoric bony fish. It is classified with the order Peltopleuriformes.
Thoracopteridae is an extinct family of prehistoric bony fish; classified with the order Peltopleuriformes. This lineage of Triassic flying fish-like Perleidiformes converted their pectoral and pelvic fins into broad wings very similar to those of their modern counterparts. However, this group is not related to modern flying fish from the family Exocoetidae, instead being a case of convergent evolution.
