On the south coast of England, forming part of Dorset’s Jurassic Coast, you’ll find the perfect horseshoe-shaped bay of Lulworth Cove. From above it looks like someone’s taken a bite out of the coastline. But when you get close up you can see the layers of rock, bent and twisted out of shape over 150 million years of geological history. The rocks here are packed full of ancient fossils, remnants of the prehistoric creatures that used to swim in the Jurassic Sea. Some of the biggest are on show in the Dorset Country Museum, but you can hunt for your own on Lulworth’s beaches. The rocks are constantly being eroded by the waves and weather, exposing new fossils, so you never know what you might come across on the shore.
