Beautiful Half Polished Ammonite - Purple Highlights

Here is a cut and polished Cleoniceras from Madagascar just shy of 6 inches wide. It is absolutely beautiful with natural purple highlights which I've only seen on a few specimens. The chambers of the ammonite have been agatized and the reverse side shows the distinctive "oak leaf" shaped sutures of this species. It's hard to believe this was alive 110 million years ago.

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.
