3.6" Fossil Nautilus (Cenoceras) With Belemnites - England

This is a 9" wide section of rock that contains a beautifully preserved nautilus of the genus Cenoceras, multiple belemnite rostrums and a partial ammonite. It was collected from the Lower Jurassic, Lower Lias of Dorset, England. The exposed nautilus is about 3.6" wide and the entire specimen measures 7.1 x 5.5". Comes with an acrylic/metal (gibson) display stand.

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!

Belemnites are probably the most well known extinct cephalopod after the ammonites. They lived during the Jurassic and Cretaceous periods and are fairly common fossils found throughout the world. They had a hard, internal, cone-shaped structure that is often preserved as a fossil, though it is not technically a shell. They had ten arms but, unlike modern squid, these arms had small hooks instead of suckers.
