A stunning example of a highly pyritised ammonite fossil of the species Eoderoceras bispinigerum from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 47 mm (1.85 inches) across. The ammonite is well preserved on both sides with highly detailed suture lines, ribbing, and especially spines. This is the rarer species of this ammonite type and it has a distinctive double row of spines on the outer whorl. They are not often found and even less often offered for sale. These are very popular ammonites but are becoming hard to find due to lack of erosion of the right layers in the cliffs. It has been sealed with a removable varnish for protection.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
