6.85" Cut & Polished Ammonite Fossil - Crystal Chambers

Here is a gorgeous cut and polished Cleoniceras ammonite fossil quarried in the Mahajanga Province of Madagascar. It's Early Cretaceous (Albian Stage) in age, or approximately 110 million years old.

These fossils exhibit beautiful mineralization within the chambers, each separated by white calcite septa (divisions). Some of the chambers are preserved as crystal lined pockets. This highly polished, exotic ammonite makes a superb display piece with great historical appeal. It comes with a pair of acrylic display stands.

Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
