5.7 Inch Cut and Polished Ammonite (Half)

Here is a large 5.7 inch wide Cleoniceras ammonite from Morocco which has been cut in half and polished. Found in Madagascar, it lived in the shallow seas during the Middle Cretaceous Period, approximately 110 million years ago. This specimen is simply beautiful with dark agatized cavities some of them lined with calcite crystals. It displays wonderfully on the included stand.

Ammonites were predatory mollusks that resembled squids with shells. These cephalopods had eyes, tentacles, and spiral shells. Though their shells resemble that of a nautilus, they are actually more closely related to living octopuses. Ammonites appeared in the fossil record about 240 million years ago, barely surviving several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
