Travel back over 110 million years to the warm prehistoric seas of the Early Cretaceous Period with this beautiful White Spine Ammonite fossil from Madagascar. Belonging to the extinct genus Cleoniceras, this ancient marine creature once drifted through oceans alongside giant marine reptiles while dinosaurs dominated the land.
This specimen showcases the intricate ribbed spiral pattern that makes ammonites some of the world’s most recognisable fossils. Its natural white mineralisation and contrasting darker chamber details create a striking appearance that collectors and fossil enthusiasts love. Over millions of years, the original shell was buried beneath ancient seabeds where minerals slowly replaced the organic material, preserving this incredible piece of natural history in stone.
Fossils from the Sakaraha region of Madagascar are highly prized for their exceptional preservation and detailed textures. Every ammonite tells a story of Earth’s ancient oceans and the remarkable creatures that once inhabited them.
