Hidden beneath the ancient seabeds of Madagascar for over 110 million years, this remarkable White Spine Ammonite fossil is a genuine relic from the Early Cretaceous oceans. These extinct marine cephalopods, belonging to the genus Cleoniceras, once floated through prehistoric waters while dinosaurs roamed the Earth above.
This specimen features the beautifully preserved spiral shell and distinctive ribbed chamber pattern that make ammonites so captivating to collectors. Natural mineralisation over millions of years has created soft earthy tones with contrasting calcified details, giving the fossil a rugged yet elegant prehistoric appearance. Every ridge and chamber tells a story of survival, burial, and fossilisation deep within ancient marine sediments.
The fossil-rich region near Sakaraha in Madagascar is famous worldwide for producing exceptionally preserved ammonites. Each piece is unique, shaped by geological processes spanning millions of years, making no two specimens exactly alike.
