Fossil Nautilus are characterized by involute or more or less convolute shells that are generally smooth, with compressed or depressed whorl sections, straight to sinuous sutures, and a tubular, generally central siphuncle.

Having survived relatively unchanged for millions of years, nautiluses represent the only living members of the subclass nautiloidea and are often considered “living fossils”.
