Where to look
Search the rock pools and loose slabs across Dunraven Bay at low water — Gryphaea oysters lie loose in the gravel and ammonite sections show on the wave-cut platform. After winter storms the fresh block falls (viewed from a distance) feed the beach for weeks.
What fossils look like here
Ammonite impressions here can be dinner-plate size, showing as coiled ridges on fallen grey-blue slabs. 'Devil's toenails' (Gryphaea) are thick, curved oyster shells lying loose in the gravel.
