'I had to pinch myself': rediscovering Darwin's fossils

A "treasure trove" of fossils - including some collected by Charles Darwin - has been rediscovered in an old cabinet.
The fossils - which had been lost for some 165 years - were found by chance in the vaults of the British Geological Survey HQ near Keyworth, UK.
The find was made by the palaeontologist Dr Howard Falcon-Lang. He told the BBC World Service that he had to pinch himself when he made the discovery.
"These are remarkable fossils that really shed light on the young Charles Darwin before he became famous, before he came clean about his theory of evolution," he said.
The fossils have been photographed and are now available to the public through a new online museum exhibit.
