A stunning example of an uncommon pyritised ammonite fossil from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 52 mm (2 inches) across with matrix, which is large for this fossil type. It represents part of a Jurassic belemnite (squid-relative) called the phragmocone (a chambered buoyancy shell). The detail in the shell is high. A nice example of an uncommon fossil. These pyrite fossils are becoming much harder to find these days due to lack of erosion of the right layers of rock.
Around 196 million years old, this fossil would make a wonderful addition to any collection
