Massive 11.3" Polished Ammonite With Stone Base

This is a stunning fossil display featuring a massive, 11.3" wide Shloenbacchia ammonite from Khenifra, Morocco. The ammonite fossil has been highly polished revealing the inner chambers lined with crystals as well as the exquisite suture pattern. Some of the surrounding rock was left in place and sculpted to create a natural base which the ammonite stands upright on.

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.
