"A cast is being made of tracks left by a two-metre long ancient animal in north east Fife. The tracks were made by a giant six-legged water scorpion called Hibbertopterus as it crawled over damp sand about 330 million years ago. It is the largest known walking trackway of a eurypterid or any invertebrate animal. The tracks were discovered by Dr Martin Whyte from the University of Sheffield while he was out walking."
