Fossil ammonite

Ammonites are molluscs that have been extinct for 65 million years. Each of these pieces are polished, in order to let us see one or more ammonite fossils. These surprising specimens are 450 million years old. They lived under the world's oceans. By looking at them, we gradually discover their secrets, like the tiny crystals lodged in the hollows of their shells.
