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 27 mm (1.1 inches) across with matrix, which is a good size for this species, and is very well preserved on both sides with great detail in the ribbing and spines and a tiny hole in the centre. 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.
