A stunning example of a highly pyritised ammonite fossil of the species Pleurechioceras congruens from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 44 mm (1.75 inches) across, which is a good size for this species. This is an uncommon species that is rarely offered for sale. It is unusual in having a distinctive ridge running along the keel of the shell and very fine ribbing. The ammonite is very well preserved, especially on one side with some of the inner whorls missing. A great example of an uncommon species that is rarely offered at this level of quality. These ammonites 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.
