A stunning example of a highly pyritised ammonite fossil of the species Echioceras raricostatum from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 18 mm (0.7 inches) across. The ammonite shell is very well preserved with great detail in the ribbing and suture lines. It has a beautiful pyritic metallic shine.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
