For decades, Dorset-based fossil hunter Chris Moore combed the cliffs and beaches around Lyme Regis and Charmouth, part of England's UNESCO-listed Jurassic Coast, gradually assembling a collection of 318 specimens spanning ichthyosaurs, fish and crustaceans, including fossils that could potentially represent species new to science. Under the region's fossil collecting code, Moore first offered the collection to the Natural History Museum in London and Amgueddfa Cymru, the national museum of Wales, giving British institutions an opportunity to acquire it before it could be sold elsewhere.
