Crystalline Hildoceras from Ilminster, Somerset, UK. Beacon Limestone Formation (Junction Bed). Approx 85mm diameter.
Difficulty: ★ ★ Moderate. Relatively easy to clean. Engraver or an air pen (air scribe).
A bit of damage to centre whorls - likely not complete to the centre which is reflected in the price. Outer whorls beautifully crystalline and orange/grey calcite which is less commonly found at the locality. Damage to part of the outer whorl (common for the locality).
