Ammonite fossils are extinct marine mollusks, which died out in the Late Cretaceous Period, 65 million years ago. The earliest traces of Ammonite date back to 420 million years ago, while the last known traces fall to 60 million years ago.
The two species of ammonites which produce the beautiful gem ammonite, are the Placenticeras Meeki, and the Placenticeras Intercalare, from the class Cephalopoda, and the order Ammonoidea. They vary in size from several inches up to two feet or more in diameter. Some of these ammonites surely broke apart before becoming imbedded in the shale where they were trapped. Others succumbed to time and pressure, and were crushed apart. Still others suffer decomposition when the forces of erosion work on them, as they approach the surface, and exposure to the elements.
These creatures that lived in these shells swam in open waters, filling chambers of the shell with gas to maintain buoyancy. Ammonites are found all over the world, however, a large majority of these ammonites comes out from Morocco.
