A stunning and large 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 62 mm (2.45 inches) across, which is large for this fossil type. There are lots of ammonites preserved in the matrix. The shells are preserved on both sides of the piece and have a great level of detail, some of the best I have seen in this fossil type. These fossils are becoming harder to find due to lack of erosion of the right layers in the cliffs. This is one of the biggest of this type I have found and had to offer in a long time.
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.
