Extinct genus of fishes

Dipteronotus Temporal range: Anisian-Carnian[1] PreꞒ Ꞓ O S D C P T J K Pg N Dipteronotus aculeatus fossil[2] Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: †Perleidiformes Genus: †Dipteronotus Egerton, 1854 Type species †Dipteronotus cyphus Egerton, 1854 Other species †D. aculeatus (Jörg, 1969) †D. gibbosus Martin, 1980 †D. olgiatii Tintori, 1990 Synonyms Praesemionotus Jörg, 1969

***Dipteronotus*** is an [extinct](/source/Extinct) [genus](/source/Genus) of marine [stem](/source/Stem_group)-[neopterygian](/source/Neopterygian) [ray-finned fish](/source/Actinopterygii) that existed during the [Middle](/source/Middle_Triassic) and [Late Triassic](/source/Late_Triassic) [epochs](/source/Epoch_(geology)) in what is now Europe (France, Germany, Italy, England) and Morocco.[2][1] As a typical feature, it had several ridge scales in front of its [dorsal fin](/source/Dorsal_fin) that created a spine-like structure.

## Taxonomy

The following species are known:[1][3]

- ***D. aculeatus*** (Jörg, 1969) - Early [Anisian](/source/Anisian) of France

- ***D. gibbosus*** Martin, 1980 - [Carnian](/source/Carnian) of Morocco ([Timezgadiouine Formation](/source/Timezgadiouine_Formation))[4]

- ***D. cyphus*** Egerton, 1854 - Late Anisian of England ([Otter Sandstone Formation](/source/Otter_Sandstone_Formation))

- ***D. olgiatii*** Tintori, 1990 - Late [Ladinian](/source/Ladinian) of Italy ([Meride Formation](https://en.wikipedia.org/w/index.php?title=Meride_Formation&action=edit&redlink=1), [Monte San Giorgio](/source/Monte_San_Giorgio))

The species *D. ornatus* Bürgin 1992 from the [Besano Formation](/source/Besano_Formation) of Switzerland has been reassigned to the [polzbergiid](https://en.wikipedia.org/w/index.php?title=Polzbergiidae&action=edit&redlink=1) genus *[Stoppania](https://en.wikipedia.org/w/index.php?title=Stoppania&action=edit&redlink=1)*.[5]
