Typewritten letter dated 5 April 1956 from Edward (Ted) Ellis, Keeper of Natural History at the Castle Museum, Norwich, to Eric Blackburn of Stanhoe. Eric had found a "devil's toenail" – a fossil oyster – in Stanhoe and the letter explains what it is and how it came to be there.

Ted Ellis (1909–1986) was a distinguished Norfolk naturalist who was Keeper of Natural History from 1928 to 1954. For 40 years he wrote a daily diary column for the Eastern Daily Press, and appeared on radio and local television.

The fossil referred to is in the care of Stanhoe Archive, thanks to the generosity of Hazel, the daughter of Eric and Eva.
