Perfectly Preserved Prehistoric Print

Last month in Wales, 4-year-old Lily Wilder found a fantastic footprint on the beach. It looked like it was scratched into the rock, but it was actually a dinosaur track. The fossil footprint is 4 inches long, and possibly left by an 8-foot-long Grallator. It walked on 2 feet during the Triassic period, 215,000,000 years ago.
