6.1" Cut & Polished Ammonite Fossil (Half) - Madagascar

Cut & Polished Ammonite Fossil (Half) - Madagascar #296417

Here is a beautiful, 6.1" wide, cut and polished Cleoniceras ammonite fossil from Madagascar. These ammonites are Cretaceous in age, approximately 110 million years old. This specimen exhibits gorgeous mineralization within the chambers, each separated by white calcite septa (divisions). This highly polished, exotic ammonite makes a superb display piece with tremendous historical appeal.

This pictured half of the ammonite is included along 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.
