7.3" Cut/Polished Ammonite Pair - Agatized

Here is an 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 scepta (divisions). Some of the chambers are preserved as crystal lined pockets. The reverse side has a very beautiful, mother of pearl look to it. 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 squids with shells. These cephalopods had eyes, tentacles, and spiral shells. Though their shells resemble that of a nautilus, they are actually more closely related to living octopuses. Ammonites appeared in the fossil record about 240 million years ago, barely surviving several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
