Spherical fossil sponge (called 'porosphaera', from the cretaceous period, 70-135 million years ago) with naturally occuring, slightly tapering, hole through it. Diameter c.78mm, diameter of perforation 12mm-10.5mm, weight 480.8g. Wear around the edges of the hole may indicate that this has been suspended at some point, although the wear is not in the same position at both ends - possibly just damage. Stones with holes through them are sometimes called hag stones and are thought to have amuletic powers, warding off withcraft/bad luck etc. This was found buried beneath the floor of a 17th?/18th century building and may have been intended as a hag stone/ amulet.
