The largest dinosaur footprint ever found was recently discovered in a kind of real-life Jurassic Park—Dampier Peninsula in Northwest Australia. The footprint measured 5 feet 9 inches. The print belonged to a sauropod, a long-necked herbivore seen in most dinosaur movies. Just last summer, a team of paleontologists found a 3 feet 9 inch footprint in Bolivia that at the time was the largest ever found.
The Dampier Peninsula provides the perfect conditions for the preservation of these tracks. The peninsula was primarily tidal flats and swamps, which allowed for the prints to set and over millions of years eventually turn to stone. A 16-mile stretch of the Dampier Peninsula housed 21 different dinosaur footprints, proving to be the most diverse collection of dino track ever found on Earth. Along with the largest dinosaur track ever found, the team from the University of Queensland discovered tracks of a stegosaurus, the first piece of evidence showing the spiked herbivore once lived on the continent.
