A stunning example of a highly pyritised multi-ammonite fossil of the species Crucilobiceras densinodulum from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 47 mm (1.85 inches) across with matrix which is large for this species. The ammonites are well-preserved on both sides of the matrix and there are around seven shells including one very large individual which has a bite mark on the outer whorl. The ribs are very finely defined and the golden colour is beautiful. A great example of the species. These ammonites are becoming harder to find these days.
These multi-ammonite assemblages (or 'death beds') occur when lots of 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
