Opalised Cleoniceras Ammonite Fossil 50x50mm Madagascar in Presentation Box

These stunning 120-million-year-old Opalised Cleoniceras Ammonite fossils are from the Lower Albian stage of the Cretaceous era and were found in Madagascar.  Cleoniceras is a well-known genus of ammonite distinguished by its finely ribbed, tightly coiled shell and the notable appearance of its opalised mother of pearl like finish when polished.  These marine cephalopods thrived in warm, shallow, silica-rich seas, where the organic material was replaced by the surrounding minerals to become these lovely ammonite fossils that are known for their distinctive shiny appearance.
