Summary:
A trio of paleontologists has discovered a remarkable new tracksite in Alaska's Denali National Park filled with duck-billed dinosaur footprints -- technically referred to as hadrosaurs -- that demonstrates they not only lived in multi-generational herds but thrived in the ancient high-latitude, polar ecosystem. The article provides new insight into the herd structure and paleobiology of northern polar dinosaurs in an arctic greenhouse world.
