Lyme Regis a coastal town in West Dorset, England, situated 25 miles west of Dorchester and 25 miles (40 km) east of Exeter. The town lies in Lyme Bay, on the English Channel coast at the Dorset-Devon border. It is nicknamed "The Pearl of Dorset." The town is noted for the fossils found in the cliffs and beaches, which are part of the Heritage Coast—known commercially as the Jurassic Coast—a World Heritage Site.
Lyme Regis is really the birthplace of British fossil hunting. Large fossils and the remains of sea creatures like plesiosaurs are still found today – although it’s more likely that you’ll find an ammonite, which are more common here.
