Abstract
The two quotes above are representative of the controversy concerning the age of Nautilus, the last externally shelled cephalopod. If we accept the first age estimate, we would have to include Nautilus as a living fossil, the end member of a clade that has survived for a long time and undergone little morphologic change.
