World’s biggest dinosaur footprint discovered in ‘Australia’s own Jurassic Park’
More than 100 million years ago, on a muddy stretch of land that is now Australia, nearly two-dozen species of dinosaur once roamed.
There were duck-billed ornithopods, which left long, three-toed tracks in their wake. Heavy armored dinosaurs pressed large, tulip-shaped prints into the soil. Predators scratched the ground with their talons. And the feet of gigantic, long-necked sauropods created bathtub-sized depressions in the dirt.
