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 41 mm (1.61 inches) across and consists of two large ammonite shells with their centres missing in a pyrite matrix. The detail in the fossils is great, they are well defined and the golden colour and shine is beautiful. These fossils are becoming hard to find due to a lack of erosion of the correct 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.
