The rocky shore beside Hook Lighthouse, in County Wexford, exposes fossil-rich Carboniferous limestone. Crinoids, brachiopods, corals and delicate bryozoan colonies can be seen weathering from its bedding surfaces. This is an exposed Atlantic headland and a protected shore: enjoy the fossils in place, with photography and careful observation at the centre of your visit. Carboniferous, Foreshore, Rating: ♦♦♦♦
