A stunning and large example of a highly pyritised ammonite fossil of the species Eoderoceras (Eteoderoceras) armatum from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 82 mm (3.22 inches) across with matrix which is large for this species. It is beautifully preserved on both sides with some unusual pyrite matrix covering parts of the shell. The suture lines are clearly visible and very striking and the detail in the ribs is very good. It has a lovely pyritic golden colour and shine. These fossils are very hard to find these days due to a lack of erosion of the right layers in the cliffs on the Jurassic Coast.
Around 196 million years old, this fossil would make a wonderful addition to any collection
