Kosmoceras sp. Ammonite, Jurassic. Ashton Keynes UK.

This Ammonite with its impressive detail has been expertly prepped. This ammonite as suggested in the name is commonly found at Ashton Keynes, UK and dates back to the Jurassic era circa180 million years ago. This specimen was found in the UK, specifically at Ashton Keynes. The detail of this Ammonite is just superb, with clear edges and ridges all the way through to the mid section. Ammonites are an extinct sea dwelling cephalopod and these ancient molluscs are closely related to the Nautilus which are still alive in our seas today. What you see with these fossils is the detailed hard shell that would have protected the soft bodied tissue inside. As with most cephalopods these animals would have moved through the waters by projecting a jet of water in the opposite direction to the direction they need to move.
