After 80 million years of baking heat the deserts began to disappear – Britain was back on the move. We were about to enjoy a much balmier time… and to find out more, I need to visit our very own Jurassic coastline that stretches the width of Dorset from Lyme Regis to Swanage. All along this coast the sea is eating away at the cliffs uncovering clues and scattering them on the beach. Every pebble under your feet could be 200 million years old. Rocks like these can tell us a huge amount about that time. Alan Titchmarsh finds an ammonite fossil. This animal didn’t live in the desert, but in the sea – the super-continent was breaking up and we inherited some superb beachfront real estate. Our south coast would have been like the Caribbean. These Jurassic seas weren’t just filled with ammonites – they were home to all kinds of fantastical creatures. For the next 70 million years Britain was a tropical paradise of inviting lagoons and endless reefs. In these clear warm waters a new piece of the British landscape was being created.
