A stunning example of a highly pyritised ammonite fossil of the species Crucilobiceras densinodulum from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 25 mm (1 inch) across. The ammonite shell is very well preserved with great detail in the ribbing and suture lines. These larger Crucilobiceras ammonites are uncommon as most are much smaller.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
