Ceratodontidae is anextinctfamily oflungfish with fossils known worldwide from the earliestTriassic to theEocene.
Although the extantQueensland lungfish was formerly also classified in this family due to its similar appearance, phylogenetic and morphological evidence indicates that it belongs in a different family,Neoceratodontidae. A morphological study by Kempet al (2017) proposed that Ceratodontidae was more closely related to modernAfrican (Protopteridae) andSouth American lungfish (Leptosirenidae) than Queensland lungfish.[1] However, Brownstein, Harrington & Near (2023) found Ceratodontidae to lie outside thecrown group of modern lungfish, with all modern lungfish more closely related to each other than to Ceratodontidae.[2]
The following genera are known from the family:[3]
Paraceratodus was also classified in this family but phylogenetic evidence supports it being the most basal member ofCeratodontoidei.[1][4]
