Black Cleoniceras Ammonite - 3.2" (Half)

 
This is an unusual offering from Madagascar. While ammonite fossils of the genus Cleoniceras are common and widely available, black ones are hard to come by. They are collected from a different location and the difference in coloration would be due to changes to the rock after the ammonite was fossilized. You'll notice some of the attached matrix on the back side is a deep orange color instead of the typical grey from the other locality further hinting at these changes.

This ammonite half is 3.2 inches in diameter and has been polished to reveal the inner detail. Many of the chambers have been preserved as pockets of crystals.

Includes an acrylic display stand.
