6" Cut & Polished Ammonite Fossil - Agatized
Here is a gorgeous cut and polished Cleoniceras ammonite fossil quarried in the Mahajanga Province of Madagascar. It's Early Cretaceous (Albian Stage) in age, or approximately 110 million years old.
These fossils exhibit beautiful mineralization within the chambers, each separated by white calcite septa (divisions). Some of the chambers are preserved as crystal lined pockets. This highly polished, exotic ammonite makes a superb display piece with great historical appeal. It comes with a pair of acrylic display stands.

About Ammonites
Ammonites were ancient marine cephalopods, similar to today's squids and octopuses, but with a defining feature: their distinctive, tightly coiled spiral shells. These shells, resembling those of modern nautiluses, served as both a protective home and a buoyancy aid, allowing ammonites to navigate the prehistoric seas with ease. First emerging around 240 million years ago in the Triassic Period, ammonites thrived for over 175 million years, adapting through numerous forms and sizes. As predatory creatures, they likely fed on smaller marine organisms, using their tentacles to capture prey. However, their long reign came to an end 65 million years ago at the close of the Cretaceous, coinciding with the mass extinction event that also eliminated the dinosaurs.
