A stunning example of an uncommon calcite ammonite fossil of the species Parkinsonia sp. from the Jurassic Coast beach of Burton Bradstock, Dorset UK.
The fossil ammonite measures 150 mm (5.85 inch) across, is very well preserved, and has been prepared out of the rock to reveal the whole shell. The ribs are very finely defined, and the mottled colour is beautiful. A great example of the species and impressive in the flesh. The fossil weighs 765 grams. These ammonites are hard to find in this condition due to a lack of erosion on this part of the coast.
Around 168 million years old (Bajocian, Middle Jurassic), this fossil would make a wonderful addition to any collection.
