Cleoniceras cleon

Ammonites represent some of the most beautiful fossils in the world of paleontology. Once a dominant species on our planet, Ammonites were found in oceans across the globe for almost 350 million years, ranging in size from less than an inch, to the monstrous proportions seen here. The architectural elements of this 84 million year old fossil remain remarkably detailed, vastly contributing to its aesthetic. Furthermore, this incredible specimen has been sliced in half to expose the remarkable mineral replacement that has occurred in its inner living and buoyancy chambers. Crystals of calcite in a gorgeous range of caramel-honey hues fill the interior, and the sliced faces have been brought to a high polished finish further to enhance the incredible natural beauty.

While most ammonites from Madagascar are fairly small in size and rarely get bigger than the size of a dinner plate, the present specimen is an incredible 43 inches wide and contains over 70 distinct chambers. The exteriors have also been polished, and the result is a matching pair of display pieces of both immense size and immense aesthetic appeal. Accompanied by custom steel stands.
