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 36 mm (1.4 inches) across, which is very large for this species, and is very well preserved on both sides with great detail in the ribbing and spines. It has a beautiful pyritic metallic shine.
These large Crucilobiceras ammonites are hard to very and very popular.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
