5.25" Agatized Ammonite Fossil (Half) - Madagascar

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 cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
