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 40 mm (1.55 inches) across. There are two ammonites in the matrix, one of which is very large for this species and both of which are all very well preserved. The shells are preserved on both sides of the piece. The detail in the fossils is great, they are well defined and the golden colour is beautiful. These fossils are becoming harder to find due to lack of erosion of the right layers in the cliffs.
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
