Fossil ammonite on the Glamorgan Heritage Coast – part of the Wales Coast Path

The Glamorgan Heritage Coast promises stunning cliff scenery and 300 million year-old fossils, explains Dennis Kelsall

THE CLIFFS BEYOND OGMORE-BY-SEA display a wonderful mixture of bedded limestones, shale and conglomerate, variously coloured golden to white, grey and blue. The oldest rock lies at the base, a grey Carboniferous limestone that was laid down more than 300 million years ago in a sub tropical sea. It is rich in aquatic fossils such as crinoids, brachiopods and corals.
