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
