Temporal range: Viséan [1]
Scientific classification Edit this classification
Domain: Eukaryota
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Family: Cosmoptychiidae
Gardiner, 1963
Genus: Cosmoptychius
Traquair, 1877
Species:
C. striatus
Binomial name
Cosmoptychius striatus
( Agassiz, 1835)
Synonyms
  • Amblypterus striatus Agassiz, 1835
  • Cosmoptygius Traquair, 1877 (misspelling)

Cosmoptychius is an extinct genus of freshwater and estuarine ray-finned fish that lived during the Mississippian epoch. [1] [2] It contains a single species, C. striatus from the Visean of Scotland. [3] It has a wide stratigraphic range in the Wardie Shale, with many specimens known. [4] [5]

Initially classified as either a palaeonisciform (a now- paraphyletic group of basal actinopterygians) [6] or the earliest stem-group neopterygian, it is now generally considered a stem-group actinopteran. [7]
