Nice Harpoceras from Ilminster, Somerset, UK. Beacon Limestone Formation (Junction Bed). Approx 145mm diameter (large).
Difficulty: ★ ★ Moderate. Relatively easy to clean. Engraver or an air pen (air scribe).
Outer whorl damaged and a bit pitted - follows the sutures. Should be quite a nice example when prepped. May not be complete to the centre which is reflected in the price. Nice sutures and colouring.
