Opalescent Ammonite Fossil . Ammonites from the Bearpaw Formation such as this are regarded as some of the most beautiful fossils known to man. This remarkable display piece shows one side of the ammonite, Placenticeras costatum, within a rocky matrix, dating to the late Cretaceous, around 75 million years ago. The nacre within the shell of this prehistoric creature has turned into a dazzling multicoloured stone, sometimes referred to as Ammolite. The beautiful, iridescent colour, changing with the light, is a unique phenomenon found in fossils of the Bearpaw Formation, Alberta, Canada. A bracket is attached at the back for wall mounting.
