Australian researchers were delighted to discover what they’re calling the world’s largest dinosaur footprint. The track is 1.7m, and the team spent 5 years documenting thousands of other dinosaur footprints. Queensland Paleontologist Steve Salisbury and his team say the footprints could be anywhere from 90-115 million years old. The team had to use drones and laser scanners to capture any images they could, as many are only visible when the tide retreats. Cool! That’s one big dinosaur track..
