One of Kilmarnock's oldest residents: 400 million years old!
The fossil scorpion was found by John Hunter-Selkirk, a mine manager from Braidwood in Lanarkshire and one of the most important collectors of his day.
The scorpion was about 3cm long and this fossil is one of the oldest in the world. It has been in the Dick Institute Collection for about 100 years and was once described as "the most valuable fossil of its kind in existence" by curators at the British Museum.
