For the first time, dinosaur bones have been uncovered in Alaska's Denali National Park, according to the U.S. National Park Service and paleontologists from the University of Alaska Fairbanks who made the find during an expedition in July.
In all, four bone fragments were found - the largest only inches long but clearly belonging to a large animal, the scientists said. The shape of one of the specimens, a fossilized tendon, suggests to the researchers that the bones likely came from a large hadrosaur, a duck-billed herbivore that was among the most common large animals in the Alaska of the Cretaceous.
The find was a long time in coming. It was not until 2005 that the first evidence of dinosaurs was found in the park, in the form of tracks made by a theropod in the park's Cantwell Formation. In the intervening years, thousands of tracks have been found. Until now, though, bones have remained elusive.
