6.7" Cut & Polished, Agatized Ammonite Fossil - Madagascar

This is a beautiful, 6.7" wide, cut and polished Cleoniceras ammonite fossil from Ambatolafia, Madagascar. These ammonites are Late Cretaceous (Albian Stage) stage in age, or approximately 110 million years old.

It 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.

Both halves are included along with a pair of display stands.

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.
