Huge, 10.2" Sliced Ammonite Fossil (Half) - Crystal Filled

Here is a huge, cut and polished Cleoniceras ammonite fossil from the Cretaceous of Madagascar. These fossils exhibit gorgeous mineralization within the chambers, each separated by white calcite scepta (divisions). Many of the chambers are preserved as deep pockets full of druzy crystals. This highly polished, exotic ammonite makes a superb display piece with tremendous historical appeal.

It comes with an acrylic display stand.

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. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
