This is awesome. One of the most impressive archaeological discoveries of the decade was just made in the UK – by a 4-year-old girl.

4-year-old Lily Wilder of Wales was walking along a beach with her dad and their dog when she pointed out a 4-inch-wide dinosaur footprint – an exceptionally well-preserved one that scientists estimate is over 220 million years old. Researchers aren’t sure what type of dinosaur left the footprint, but say it’s a “stunning” sample with “every detail” visible. As for Lily, Her mother said she’s “really excited”, but of course “doesn’t quite grasp how amazing it is”.

What’s the oldest thing you’ve ever found?
