Jurassic fish of North America

Lepidotes (from , 'covered with scales') (previously known as Lepidotus) is an extinct genus of Mesozoic ray-finned fish. It has long been considered a wastebasket taxon, characterised by "general features, such as thick rhomboid scales and, for most of the species, by semi-tritorial or strongly with dozens of species assigned to it. Fossils attributed to Lepidotes have been found in Jurassic and Cretaceous rocks worldwide. It has been argued that Lepidotes should be restricted to species closely related to the type species L. gigas, which are only known from the Early Jurassic of Western and

Ceratodus (from and ) is an extinct genus of freshwater lungfish that was found worldwide during the Mesozoic Era. It has been described as a "catch all", and a "form genus" used to refer to the remains (typically toothplates) of a variety of lungfish belonging to the extinct family Ceratodontidae. Fossil evidence dates back to the Early Triassic. A wide range of fossil species from different time periods have been found around the world in places such as the United States, Argentina, Greenland, England, Germany, Egypt, Madagascar, China, and Australia. Ceratodus is believed to have become ext

Aspidorhynchus (from Ancient Greek ἀσπίς (aspís), meaning "shield", and ῥύγχος (rhúnkos), meaning "snout") is an extinct genus of predatory ray-finned fish from the Middle Jurassic to the earliest Cretaceous. Fossils have been found in Europe, Antarctica and the Caribbean.

Gyrodus (from , 'curved' and 'tooth') is an extinct genus of pycnodontiform ray-finned fish that lived from the Middle Jurassic (Bajocian) to the Early Cretaceous (Barremian).

Caturus (from , 'down' and 'tail') is an extinct genus of predatory marine fishes in the family Caturidae in the order Amiiformes, related to modern bowfin. It has been suggested that the genus is non-monophyletic with respect to other caturid genera.
