3.9" Cut & Polished Nautilus (Cenoceras?) Fossil - France

This is a fossil nautilus (Cenoceras sp.?) that was collected near Lyon, France. It is Toarcian (Jurassic period) in age, or approximately 180 million years old. It has been cut in half and polished to a glossy finish, revealing the calcite crystal lined chambers. It has been cut flat along one edge, however it comes with an acrylic display stand for preferred presentation.

The shell of a Nautilus is made up of two layers. The inner layer has the iridescent shine while the outer layer provides protection from external forces. Inside the shell are septa which divide the living area of the shell into compartments and help the animal maintain balance and position in the water column.

Nautilus are "living fossils" in that species similar to this one still exist in our oceans.
