Frozen in stone for more than 110 million years, this authentic White Spine Ammonite is a remarkable survivor from the ancient seas of the Early Cretaceous Period. Once part of the extinct genus Cleoniceras, this marine cephalopod drifted through warm prehistoric oceans while dinosaurs roamed the continents above.
This Madagascan specimen displays a beautifully preserved spiral shell with pronounced ribbed chambers and natural mineral textures created through millions of years of fossilisation. The soft sandy tones, contrasting calcified details, and naturally weathered surface give the fossil an ancient character that feels truly untouched by time. Its thick shell profile adds impressive depth and dimension, making it an eye-catching display piece from every angle.
Collected near Sakaraha in Madagascar, one of the world’s most famous ammonite fossil regions, this specimen offers a genuine glimpse into prehistoric marine life. Every ammonite from this area is unique, shaped by geological processes that preserved these creatures beneath ancient ocean sediments for countless ages.
