Ammonite

Additional images

This ammonite is probably from the Portland Sand. Ammonites are one of the most commonly-found fossils. They are extinct marine creatures – predators that moved through the water by jet-propulsion. We know this because the nautilus, the closest living relative to the ammonite, still survives today in the Pacific and Indian Oceans.
