Smallmouth Sands, located within Portland Harbour near Weymouth, is one of the UK’s most remarkable yet often overlooked fossil sites, exposing the Lower Jurassic Kimmeridge Clay. It is one of the most diverse assemblages of Kimmeridge Clay reptiles anywhere in the world. Fossils are typically tiny but abundant, with collectors finding vertebrate remains, fish, and shells scattered across the foreshore, especially after favourable tides and storms.Jurassic, Foreshore, Rating: ♦♦♦♦
