Uncovering Denali National Park's Dinosaur 'Coliseum': Scientists Investigate

Scientists have discovered and documented the largest known single dinosaur track site in Alaska, located in Denali National Park and Preserve. Dubbed "The Coliseum," the site is the size of one-and-a-half football fields and contains layer upon layer of dinosaur tracks preserved in rock. The tracks provide insights into the diverse species of dinosaurs that thrived in Interior Alaska nearly 70 million years ago, including plant-eating duck-billed and horned dinosaurs, as well as carnivores like raptors and tyrannosaurs. The site also reveals evidence of fossilized plants, pollen grains, and freshwater shellfish, painting a picture of the ancient ecosystem. Preserving fossil sites like The Coliseum is crucial, and further exploration is expected to uncover more surprises.
