8.6" Callovian Ammonite (Choffatia) Fossil - France
This is a beautiful, 8.6" wide, natural association of two ammonite fossils, collected from a location near Poitiers, France. They are Callovian (Jurassic period) in age, or approximately 165 million years old. The largest ammonite (Choffatia sp.) measures 5.3" wide, and the smaller ammonite (Hecticoceras sp.?) to the left is 3.1" wide.
The base of the rock has been cut flat for aesthetic presentation of the fossils.

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.
