About Ammonites

Ammonites are extinct coiled shell marine cephalopods whose shells were divided into chambers by walls with intricate suture patterns. They are more closely related to octopus, squid and cuttlefish than to the nautilus, and they died out around the end Cretaceous extinction about 66 million years ago.
