Polycyphus normannus desor, 1856 into a Hemicidaris luciensis d'Orbigny, 1850 Bathonian Luc sur Mer Normandy France

Very unusual----I like the two together, that doesn't happen very ofter. Spectacular specimen---Tom

Wow! I agree with Tom, very unusual indeed!

Belle pièce Gery! I got them too but close together
