Alaska's Dinosaur Coliseum: Unveiling Ancient Footprints

Scientists have discovered a 20-story cliff in Denali National Park, Alaska, covered in fossilized dinosaur footprints from around 70 million years ago. The diverse array of tracks includes various large plant-eating and carnivorous dinosaurs. The footprints were lifted and tilted due to tectonic plate collision, revealing a complex patchwork of detailed footprints. The site, nicknamed "The Coliseum," also contains fossilized plants, pollen, shellfish, and bird footprints, providing insights into the ecosystem of the time.
