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 31 mm (1.2 inches) across, which is 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.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
