A stunning example of a calcite ammonite fossil of the species Parkinsonia raricostata from the Jurassic Coast beach of Burton Bradstock, Dorset UK.
The fossil ammonite measures 133 mm (5.25 inch) across, which is large for this species. The ammonite is well preserved and has been prepared out of the rock to reveal the whole shell. The ribs are very finely defined, and the colour is beautiful: a mix of different yellows and browns. The outer whorl is worn on one side but the central whorls are preserved in solid crystalline calcite underneath the darker shell. A great example of the species and impressive in the flesh. The fossil weighs 450 grams. This species is not often offered up for sale.
Around 168 million years old (Bajocian, Middle Jurassic), this fossil would make a wonderful addition to any collection.
