In the 1840s a bed of 'coprolites', thought by some to be fossilised dinosaur droppings, was discovered in the Cambridgeshire fens. Rich in phosphate it was much in demand by the nation's manure manufacturers. By the mid-1860s it was being dug up across much of central Bedfordshire. This book investigates the social, economic and archaeological impact of the fossil diggings in Sandy and Potton, small market towns between Cambridge and Bedford.
