Description
These whole irridecent ammonites measure between 30-40mm.
These ammonite fossils come from the Cretaceous Period, a geological era spanning approximately 145 to 66 million years ago. Madagascar is world-renowned for its exceptionally preserved ammonite deposits, formed within marine sedimentary environments that once lay beneath warm, shallow Cretaceous seas. The region’s fossil-rich limestone and marl layers provide excellent conditions for the preservation of both external shell structure and internal suture patterns.
