A stunning and large example of a highly pyritised multi-ammonite fossil containing the species Crucilobiceras densinodulum from the world famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 45 mm (1.8 inches) across with matrix which is a good size for this type of fossil. The pyrite matrix contains two beautiful ammonite shells - one on each side of the piece. The ammonites are very well preserved with great detail and the whole piece has a wonderful pyritic colour and shine. These beautiful fossils are getting much harder to find.
These multi-ammonite assemblages (or 'death beds') occur when multiple shells came together on the seafloor before being fossilised together, often collecting around an obstacle in the mud like a piece of wood or larger shell. They are a beautiful snapshot of life (and death) on the seafloor almost 200 million years ago.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
