Nautilus

Additional images

This specimen has been sectioned and shows interesting internal structures. The chambers have been infilled with calcite crystal. Also visible is the siphuncle, a tube through which the creature could adjust the amount of gas or water in the chambers. This is not a complete shell – the body chamber is missing (the long outer chamber in which the soft parts were housed).
