Beautiful Inch Dark Color Split Ammonite (Half) #369

Here is a jaw dropping Cleoniceras ammonite from Madagascar which has been cut in half and polished to reveal all of the inner detail. 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 both agatized and calcite crystal lined cavities. The polished back side displays some of this ammonites oak leaf shaped sutures.

It 3.5 inches wide and 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.
