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 72 mm (2.82 inches) across, which is a good size for this species. The ammonite is well preserved on both sides with highly detailed suture lines, ribbing, and spines. This is the rarer species of this ammonite type and it has a double row of spines. 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.
