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 30 mm (1.2 inches) across, which is a good size for this species. The ammonite shell is very well preserved with great detail in the ribbing and suture lines. It is clean to the centre on one side with some pyrite matrix on the other. It has a beautiful pyritic metallic shine. These large Crucilobiceras ammonites are uncommon as most are much smaller.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
