This is a 100% genuine opalised Cleoniceras ammonite half fossil. Discovered in the Mahajanga jungle in Madagascar, it is from the Lower Albian stage of the Cretaceous era about 110 million years ago. The fossil has been carefully cut in half and polished inside,
revealing intricate swirls in the organic shell. Agatised sections are also
visible, formed when silica-rich water seeped into the shell’s hollow chambers and
crystallised, leaving translucent pockets with shimmering, geode-like interiors.
Cleoniceras is a well-known genus of ammonite distinguished by its finely ribbed, tightly coiled shell, which has a near-perfect logarithmic spiral reflective of the Fibonacci sequence found across nature.
