Ammonite Fossils

Ammonites are an extinct subclass of cephalopods, whose present-day descendants include the octopus, squid, and nautilus. Ammonites lived in the late Cretaceous period making them approximately 65 to 400 million years old. Their well-preserved fossilized shells are found today and often are cut and polished. Small ammonites are often used in jewelry design, while larger pieces are prized as display keepsakes.
