Description
Now available is a genuine ammonite fossil pair from the Cretaceous Period, discovered in the fossil-rich limestone beds of Madagascar, and dated to approximately 100 million years ago. These extinct marine animals once roamed the warm prehistoric seas, and their spiral shells have become some of the most recognisable and collectible fossils in the world.
This particular specimen has been carefully cut in half and polished, revealing the stunning internal chamber structures, filled with natural mineralisation that may include shades of amber, honey, cream, or even subtle opal-like iridescence depending on the mineral content.

About Ammonites:
Ammonites were marine cephalopods, closely related to modern squid, octopuses, and cuttlefish, although they more closely resemble the shell-bearing nautilus. They first appeared during the Devonian Period and thrived until their extinction at the end of the Cretaceous Period, approximately 65 million years ago, during the same mass extinction event that wiped out the dinosaurs.
The ammonite’s shell was divided into a series of chambers. The animal lived in the largest outer chamber and used the inner chambers to control buoyancy in the water. The beautiful internal divisions seen in sliced ammonite fossils are called septa, which formed the boundaries of these chambers.
