The tracks of the 1.6 metre (5ft) long creature, called Hibbertopterus, show that although it normally lived underwater, it could also crawl on to land.
Martin Whyte, from the University of Sheffield, found the scorpion tracks during geological fieldwork in central Scotland. "I came across a block of sandstone and noticed a strong central groove with three rows of crescent shaped footprints on either side," he says.
Fossil parts from scorpion like creatures have been uncovered previously in the same area and Dr Whyte immediately realised that these gigantic tracks could only belong to the biggest scorpion, known as Hibbertopterus. Until now most scientists believed that Hibbertopterus was only aquatic, but the new tracks show that it could venture on to land.
"The deep central groove was made as it dragged its tail along. If it had been underwater the tail would have been buoyed up by water," said Dr Whyte."
