These fossils are 100% genuine Opalised Cleoniceras Ammonites. Discovered in the Mahajanga jungle in Madagascar, they are from the Lower Albian stage of the Cretaceous era about 110 million years ago.
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.
These marine cephalopods thrived in warm, shallow, silica-rich seas, where the organic material was replaced by the surrounding minerals to become these remarkable ammonite fossils that are known for their distinctive opalised mother of pearl like finish.
