More than a hundred dinosaur footprints have been discovered on the Isle of Skye. The tracks - which look like rock pools - were created by huge plant-eating sauropods around 170 million years ago. The footprints were found on the island's northern shoreline and the researchers from the University of Edinburgh believe it's one of the biggest track sites ever found in the UK. Paleontologist Tom Challands from Edinburgh explained the difficulty he and his colleagues face in identifying which species made the impressions: "We can't tell exactly which dinosoar they came from [...] we still need to study them, but judging by the density we know there were numerous animals", he said.
