Footprints from the Isle of Skye in Scotland, formed around 170 million years ago, were attributed to early relatives of duck-billed dinosaurs. The study appeared in the Proceedings of the National Academy of Sciences. Funding came from the National Geographic Society, the Leverhulme Trust, and other organizations.
