Rare dinosaur footprints found in Alaska's National Park
Thursday, July 10, 2014, 8:59 AM - A new dinosaur track site has been discovered in Alaska's Denali National Park.
Paleontologists from the Perot Museum of Nature and Science documented the find.
They say it shows multi-generational herds of duck-billed dinosaurs thrived in the ancient ecosystem.
"We had mom, dad, big brother, big sister and little babies all running around together," said paleontologist Anthony Fiorillo in a Discovery News report. "As I like to tell the park, Denali was a family destination for millions of years, and now we've got the fossil evidence for it."
Experts say this discovery adds to the growing conviction that "dinosaurs lived at polar latitudes year-round during the Late Cretaceous Period, about 70 million years ago."
The duck-billed dinosaur track site specimens are on display at the museum in Dallas.
The scientific paper on the discovery is published in Geology.
