3.6" Polished Fossil Nautiloid (Cymatoceras) - Madagascar
This is a beautiful 3.6" fossil nautilus (Cymatoceras) from the Cretaceous aged formations of Madagascar. It is polished to highlight the details. These nautiloids are much rarer that the ammonites so frequently seen.
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.
