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 75 mm (2.91 inches) across with matrix which is large for this species. It is beautifully preserved, especially on one side. The ribs are very finely defined and the colour is beautiful. A great example of this uncommon species which has much thicker ribs than the more common species of this genus and has a double row of spines. These ammonites are becoming harder to find these days. This one is a real beauty.
Around 196 million years old, this fossil would make a wonderful addition to any collection
