CLEONICERAS AMMONITES

Cleoniceras Ammonites from Madagascar are prized Cretaceous fossils known for their intricate suture patterns, internal chamber structures and vibrant natural colors, often featuring shades of red, orange, and brown. These Ammonites, dating back around 110 million years, frequently display an iridescent sheen due to Aragonite layers in their shells, giving them a opalescent look.
