Biology:Colobodus
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]
