Extinct genus of fishes
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.
