5.6" Cut & Polished Ammonite Fossil (Half) - Madagascar
This is a stunning, 5.6" wide cut and polished Cleoniceras ammonite fossil from Madagascar, dating back to the Cretaceous Period approximately 110 million years ago. The interior chambers display beautiful natural mineralization, with each chamber clearly defined by bright white calcite septa that create a dramatic contrast against the darker fossilized shell. Meticulously polished, the ammonite reveals its intricate internal structure and eye-catching patterns, making it an exceptional and visually rich display specimen.

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.
