Prehistoric lungfish genera

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

Dipterus (from , 'two' and 'wing') is an extinct genus of freshwater lungfish from the middle Devonian period of Europe and potentially North America. The genus was established by Adam Sedgwick & Roderick Murchison in the year 1828. It was one of the first lungfish to be described by science. thumb|left|Restoration thumb|left|Illustration of Dipterus valenciennesiIn most respects, Dipterus, which was about long, closely resembled modern lungfish. Like its ancestor Dipnorhynchus, it had tooth-like plates on its palate instead of real teeth. However, unlike its modern relatives, in which the do

Ferganoceratodus (from Fergana + Ceratodus) is a genus of prehistoric freshwater lungfish known from worldwide during the Mesozoic. Based on morphological evidence, it has either been recovered as a basal member of the Ceratodontiformes or to be the sister group of the Neoceratodontidae (containing the extant Australian lungfish).

Dipnorhynchus is an extinct genus of marine lungfish from the middle Devonian period (Emsian) of Australia.

Arganodus is an extinct genus of freshwater lungfish that had a wide global distribution throughout much of the Triassic period, with a single species surviving across Gondwana into the Cretaceous. It is the only member of the family Arganodontidae, although it is sometimes placed in the Ceratodontidae or synonymized with the genus Asiatoceratodus.

Soederberghia is an extinct genus of prehistoric lungfish that lived during the late Devonian period.

Griphognathus (from 'riddle') and 'jaw') is an extinct genus of lungfish from the late Devonian period of Europe and Australia.

Rhinodipterus is an extinct genus of prehistoric dipnoan sarcopterygians or lobe-finned fish, that lived in the Frasnian stage of the Devonian period. It is believed to have inhabited shallow, salt-water reefs, and is one of the earliest known examples of marine lungfish.
