Cut & polished ammonite fossil – genuine cretaceous madagascar specimen – beautiful internal chambers – with certificate of authenticity

Description

Offered here is a genuine, cut and polished ammonite fossil from the Cretaceous Period, discovered in the fossil-rich deposits of Madagascar. These beautiful marine fossils date back approximately 100 to 65 million years, showcasing the incredible biodiversity that once thrived in Earth’s ancient seas.

This ammonite specimen has been expertly sliced in half and polished to a smooth finish, revealing the exquisite internal chamber structure that once formed part of a living marine predator’s buoyancy system. The interior of the shell displays a mesmerizing arrangement of calcite-filled chambers, often in shades of amber, honey, brown, or deep earthy tones, with stunning natural crystalization and intricate fossil patterns. Each ammonite slice is a unique piece of natural art.

Ammonites were free-swimming marine animals that thrived in oceans across the globe for over 300 million years, until their extinction at the end of the Cretaceous. Despite their snail-like appearance, ammonites were not gastropods. They are actually more closely related to today’s coleoid cephalopods—including octopuses, squid, and cuttlefish—than to any shelled animal alive today.

The name “ammonite” is derived from the Egyptian god Ammon, whose spiral ram’s horns these fossils resembled. Their coiled, chambered shells provided buoyancy control, helping them navigate the seas in search of prey.
