Ceratodontidae is an extinct family of lungfish with fossils known worldwide from the earliest Triassic to the Eocene.
Taxonomy
Although the extant Queensland 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 Kemp et al (2017) proposed that Ceratodontidae was more closely related to modern African (Protopteridae) and South American lungfish (Leptosirenidae) than Queensland lungfish.[1] However, Brownstein, Harrington & Near (2023) found Ceratodontidae to lie outside the crown group of modern lungfish, with an estimated Paleozoic divergence from them, whereas Neoceratodontidae had a Mesozoic divergence from Protopteridae and Lepidosirenidae.[2]
Genera
The following genera are known from the family:[3]
- †Arganodus
- †Ariguna
- †Ceratodus
- †Epiceratodus
- †Lupaceratodus Galula Formation, Tanzania, Cretaceous
- †Metaceratodus
- †Microceratodus (?)
- †Potamoceratodus
- †Tellerodus
- †Retodus
Paraceratodus was also classified in this family but phylogenetic evidence supports it being the most basal member of Ceratodontoidei.[1][4]
