Dipteronotus is an extinct genus of marine stem-neopterygian ray-finned fish that existed during the Middle and Late Triassic epochs 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 that created a spine-like structure.

Taxonomy

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

D. aculeatus (Jörg, 1969) - Early Anisian of France
D. gibbosus Martin, 1980 - Carnian of Morocco (Timezgadiouine Formation)^[4]
D. cyphus Egerton, 1854 - Late Anisian of England (Otter Sandstone Formation)
D. olgiatii Tintori, 1990 - Late Ladinian of Italy (Meride Formation, Monte San Giorgio)

The species D. ornatus Bürgin 1992 from the Besano Formation of Switzerland has been reassigned to the polzbergiid genus Stoppania.^[5]
