Caption: Ammonite fossils. Fossilized shells of two unidentified ammonites. Ammonites are extinct cephalopods that lived between 380 and 65 million years ago. They are distantly related to the modern-day nautilus and lived in coastal waters and inland seas. Many different species of ammonite existed during different geological periods. Their remains can be used for the accurate dating of marine rocks. Ammonites are therefore known as zone fossils. These specimens are from the Cretaceous period, 135 to 65 million years ago. The iridescent colours of the fossils are due to the presence of the mineral aragonite, which is composed of calcium carbonate.
