5 Inch Cut and Polished Cleoniceras Ammonite

Here is a beautiful Cleoniceras ammonite from Madagascar. It's been sliced open and highly polished. Many of the chambers within it are preserved as deep crystal lined pockets. The reverse side displays some great "mother of perl" colored shell. This is a truly beautiful fossil, can you believe it's 110 million years old?

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. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
