A stunning and huge 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 72 mm (2.85 inches) across with matrix, which is huge for this species.
The ammonite shell is very well preserved with great detail in the ribbing and suture lines in the centre of the matrix which represents the outer whorl of the shell. It is clean on one side of the matrix with a perfect centre. It has a beautiful pyritic metallic shine.
These large Crucilobiceras ammonites are uncommon as most are much smaller and they don't get much better than this! It weighs 150 grams.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
