Ammonites are extinct members of the cephalopod group of mollusks. Only a limited number of species have survived to the present day which includes the squid and the chambered nautilus. Ammonites had a multi-chambered shell, and added more chambers as it grew, always living in the outer chamber.  They lived in the Cretaceous period some 63 to 130 million years ago.
