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 86 mm (3.4 inches) across with matrix which is large for this species. The ammonite is beautifully preserved in a pyrite matrix with many of the much sought-after double row of spines that this species is known for still preserved. The ribs are very finely defined and the metallic pyrite colour and shine is beautiful. A great example of the species. These ammonites are becoming harder to find these days.
Around 196 million years old, this fossil would make a wonderful addition to any collection
