 Duck-Billed Dinosaurs’ Footprints Discovered in Alaskan Park
Paleontologists at Alaska's Denali National Park have discovered a new tracksite filled with footprints of duck-billed dinosaurs or hadrosaurs.

The discovery has demonstrated that they not only lived in multi-generational herds but thrived in the ancient high-latitude, polar ecosystem.

Anthony R. Fiorillo, curator of earth sciences at the Perot Museum of Nature and Science along with Stephen Hasiotis of the University of Kansas and Yoshitsugu Kobayashi of the Hokkaido University Museum published a paper 'Herd structure in Late Cretaceous polar dinosaurs: A remarkable new dinosaur tracksite, Denali National Park, Alaska, USA', which provides new insight into the herd structure and paleobiology of northern polar dinosaurs in an arctic greenhouse world.

Fiorillo said that Denali was one of the best dinosaur footprint localities in the world and they found so many well preserved big tracks, which was incredible.

Many of them had skin impressions, so they could see what the bottom of their feet looked like and there were many invertebrate traces like imprints of bugs, worms, larvae and more, which were important because they showed an ecosystem existed during the warm parts of the years, he further added.
