This story gets me very excited about my first forays into museum archives next month...who knows what one might find?
This beautifully presented collection of fossilised plants was found in the vaults of the British Geological Survey in Keyworth, Nottinghamshire. It contains slides displaying samples of vegetation from the Midlands, Wales, and far further afield - there are a small number of specimens which appear to have been collected by Charles Darwin whilst aboard the Beagle. Click through to the British Geological Survey website to read the fascinating story of the collection's assembly through networks of explorers, administrators and scientists.
