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 67 mm (2.63 inches) across with matrix, which is a good size for this fossil type. This is an uncommon species well known for its impressive double row of spines, which are very well preserved on this example. The ribbing, colour, and suture lines are all striking and it is a nice chunky and tactile fossil. These are very popular ammonites but are becoming hard to find due to lack of erosion of the right layers in the cliffs.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
