The photo was taken from Ligourio, Greece, at the local Natural History Museum. Ligourio is a small village near the ancient theatre of Epidaurus in Peloponnisos, Greece. It displays a unique fauna of fossilized ammonites that lived about 240 million years ago. Ammonites are index fossils. This means that we can determine the age of rocks based on the species of the ammonites found. The black crust covering the fossils indicates that at one time the sea where they were found was very deep.
