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 55 mm (2.12 inch) across which is large for this fossil type. There are around 20 ammonites along with some nice bivalves within the matrix, which is a lot for this type of fossil. The ammonites are incredibly well preserved and have a wonderful golden colour and shine. These beautiful fossils are getting much harder to find due to a lack of erosion in the correct rock layers.
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.
