Huge, 7.6" Polished Fossil Nautilus - Madagascar

This is a 7.6" fossil Nautilus (Nautilidae) from Ambatalafia, Mahajanga Province, Madagascar. This beautiful specimen has been polished to a glossy finish. This highlights the iridescent qualities of the inner shell. At the narrow part the shell the septa can be seen where the inner and outer shell have been removed.

A nautilus's shell 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 that 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": species similar to this one still exist in our oceans!
