Cosmolepis is an extinct genus of prehistoric marine ray-finned fish that lived during the Early Jurassic epoch.[2] It contains a single species, C. ornatus from the Blue Lias in what is now England. It is the only member of the family Cosmolepididae.[1][3]
It was formerly placed in the Palaeonisciformes, a group of basal ray-finned fishes that is now considered to be paraphyletic.[4][5] It is distinctive for its well-mineralized scales covered in ganoine. Its cheek and jaws have striated ridges of enamel.[6]
Specimens from the Moltrasio Formation of Osteno, Italy have been placed in this species based on non-reliable morphological features common among many "palaeoniscoid" fish, and thus may not be representatives of this taxon.[7]
