Extinct genus of fishes
Colobodus 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] [ 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]
