The Fossil Forest is the remains of an ancient forest from Jurassic times, located to the east of Lulworth Cove on the Isle of Purbeck in Dorset, England. It lies on the Jurassic Coast, on a wide ledge in the seaside cliff. The site is within some Army Ranges and thus has restricted access. Parts of forest can also be seen on the Isle of Portland and in quarries near the town of Weymouth to the west.
