The story of the word

Buckland coined the word in 1829 after Mary Anning pointed out that the spiral stones in the Lyme Regis cliffs were droppings. He broke them open, found fish scales and small bones inside, and worked out what the ichthyosaurs had been eating, which is close to the beginning of palaeoecology. Farmers then dug the beds for phosphate: Cambridgeshire had a coprolite boom in the 1850s and 1860s, with its own railway sidings.
