What is Ammonite?

Ammonites are the fossil shells of extinct marine animals related to today's octopus, squid and nautilus. They lived in the oceans for over 300 million years and disappeared about 66 million years ago in the same extinction event as the dinosaurs.

The name comes from the Egyptian god Amun, who was shown with coiled ram's horns. Polished ammonites – often cut in half to show their chambers – come mainly from Madagascar and Morocco. The iridescent gem ammolite is made from ammonite shell found in Alberta, Canada.
