Colobodus is an extinct genus of marine Triassic ray-finned fish of the family Colobodontidae and order Perleidiformes. Fossils have been found in Europe (France, Germany, Italy, Spain, Switzerland) and China, encompassing the former Tethys Ocean.^[1] It could reach body lengths of about 70 cm (2 ft 4 in).^[2]

The original type species was Colobodus hogardi Agassiz, 1844, the fossils of which are probably destroyed, therefore the new type species C. bassanii was designated.^[3]

Taxonomy

The following species are known:^[1]^[4]

†C. bassanii de Alessandri, 1910 - Late Anisian of Italy & Switzerland (Besano Formation)
†C. maximus (Quenstedt, 1867) - Anisian of Italy (Besano Formation), Anisian to Carnian of Germany (Muschelkalk)
†C. praemaximus Corroy, 1928 - Early Triassic of France
†C. koenigi Stolley, 1920 - Late Anisian of Germany (Muschelkalk) (possibly synonymous with C. bassanii)
†C. baii Sun et al., 2008 - Anisian of Guizhou, China^[5]
†C. giganteus (Beltan, 1972) - Late Ladinian of Spain (Muschelkalk)^[3]
†C. wushaensis Li et al., 2019 - Carnian of Guizhou, China^[6]

Several other species (C. stensioei, C. dealessandrii, C. stolleyi, C. cyclolepis, and C. anguillalepis) were proposed by Mutter (2002) from a single fossiliferous level from the Besano Formation, although their validity is uncertain due to the extreme morphological variety within the group.^[1]^[5]

Records of Colobodus exist outside of Europe and China, but these remains are thought to be highly questionable.^[5]
