6" Agatized Ammonite Fossil (Half) - Crystal Chambers

Agatized Ammonite Fossil (Half) - Crystal Chambers #88457

Here is an exquisite cut and polished Cleoniceras ammonite fossil from the Cretaceous of Madagascar. It exhibits gorgeous mineralization within the chambers, each separated by white calcite septa (divisions). The reverse side has a very beautiful, mother of pearl look to it. 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. 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.
