DescriptionThis is a nautiloid cephalopod, a straight-shelled relative of the modern Pearly Nautilus or Chambered Nautilus. The squid-like animal inhabited the large open end of a tapered shell. The chambers provided buoyancy as well as added strength to the shell. Other modern cephalopod molluscs include squids (some of which have a small internal shell), the shell-less octopuses and the internally-shelled cuttlefish.
