Paraceratodus is an extinct genus of prehistoric lungfish.{{Cite web|url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=194435|title=Fossilworks: Paraceratodus|website=fossilworks.org|access-date=2019-06-03}} Only one species, P. germaini, is known from the latest Permian or earliest Triassic period of Madagascar.{{Cite journal|last=Kemp|first=A.|date=1994|title=Australian Triassic Lungfish Skulls|journal=Journal of Paleontology|volume=68|issue=3|pages=647–654|issn=0022-3360|jstor=1306207|doi=10.1017/S0022336000025968|bibcode=1994JPal...68..647K |s2cid=131787091 }} Phylogenetic evidence supports it being the most basal member of the suborder Ceratodontoidei, which contains modern lungfish, and as with the rest of the order it likely diverged during the late Carboniferous.{{Cite journal|last1=Kemp|first1=Anne|last2=Cavin|first2=Lionel|last3=Guinot|first3=Guillaume|date=2017-04-01|title=Evolutionary history of lungfishes with a new phylogeny of post-Devonian genera|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|language=en|volume=471|pages=209–219|doi=10.1016/j.palaeo.2016.12.051|bibcode=2017PPP...471..209K |issn=0031-0182|doi-access=free}}
