Ammonite

Look closely and you’ll see ornate patterns, like fern leaves, on this ammonite. These are the walls that divided the chambers inside the shell. They can be used to identify different species. This species gives its name to the layer of rock in the Inferior Oolite in which it’s found, the ‘Truelli Bed’.
