Ammonites are cephalopods, Literally head/foot (in Latin cephala – head and podus foot). These creatures are related to Octopus and squid but the Cephalopods of today have lost their shells. Ammonites had hard external shells. Ammonites lived during the Jurassic and Cretaceous periods of Earth history which lasted about 140 million years. They became extinct after the cretaceous mass extinction but are survived today by a relative called the nautilus.
