Hunstanton’s striped Cretaceous cliffs offer a clear introduction to Norfolk’s marine fossils. Brown Carstone, the thin Red Chalk and pale Ferriby Chalk form contrasting layers, with belemnites, brachiopods, bivalves and occasional ammonites preserved in their rocks. Weathered material on the beach gives collectors a chance to examine fossils without approaching the cliff face, while the harder beds reward patient observation rather than force. The sequence also records missing intervals of geological time, so its colours tell only part of the story. Plan your visit around low tide and keep well clear of unstable cliffs and recent falls.
