Nautiloid
Nautilus
Chambered nautilus
Nautilus is the living chambered nautilus of the Indo-Pacific, the last shelled cephalopod; its fossil record as the genus proper extends into the Cenozoic, and 'fossil nautilus' in trade is usually Eutrephoceras, Cimomia or Aturia. Modern Nautilus shells have been CITES Appendix II since 2017, so a cut-and-polished shell needs export permits. Fossil nautiloids are not covered by CITES.
