In the early 1960s, palaeontologists exploring rural South Dakota unearthed the fossilised leg bone of a Hesperornis: a large aquatic bird rather like a penguin, which lived during the dinosaur era.
At first glance the fossil looked unremarkable. It took over half a century for scientists to recognise the bone's true significance.
This Hesperornis had survived a run-in with a plesiosaur: a marine reptile larger than a human being. It is only the second fossil found to date that shows signs of being attacked by a plesiosaur.
