Opalized Cleoniceras group
A spectacular large opalized ammonite group from Madagascar, dating to the Cretaceous Albian period (approximately 100–145 million years ago). This impressive fossil features a beautifully preserved Cleoniceras ammonite accompanied by another ammonite species, creating a striking natural composition.
Over millions of years, the original shell material was replaced by opalized minerals, giving the fossils their distinctive color, texture, and fossilized brilliance. The exceptional preservation and large size make this specimen particularly eye-catching.
Both scientifically fascinating and visually captivating, this one-of-a-kind piece makes a remarkable decorative display and a standout addition to any fossil or natural history collection.
