Arctolepis is an extinct genus of placoderm arthrodire fish which lived during the Early Devonian period (408 – 307 million years ago).[1] Fossils of Arctolepis have been found in what is now Norway and Michigan.[2]
Classification
Within Arthrodira, Arctolepis is considered a member of "Phylctaenii", a paraphyletic grouping within the clade Phlyctaenioidei, basal to the suborder Brachythoraci. Arctolepis is most closely related to Heintzosteus and Dicksonosteus.[3]
Arctolepis contains the following six species:
- †Arctolepis brevis Heintz, 1929
- †Arctolepis decipiens Woodward, 1891
- †Arctolepis lata Heintz, 1929
- †Arctolepis lewini Heintz, 1929
- †Arctolepis longicornis Heintz, 1929
- †Arctolepis solnoerdali Heintz, 1929
