Thousands of dinosaur tracks have been uncovered in Alaska along the Yukon River.
Live Science reports that the discovery was made this past summer by a group of researchers from the University of Alaska Museum. The scientists studied a span of more than 500 miles along the rocky shores of the Yukon and Tanana rivers and found more than 2,000 pounds in fossils.
Paul McCarthy, one of the researchers on the expedition, told Fox News: “We found dinosaur footprints by the scores on literally every outcrop we stopped at. I’ve seen dinosaur footprints in Alaska now in rocks from southwest Alaska, the North Slope and Denali National Park in the Interior, but there aren’t many places where footprints occur in such abundance.”
McCarthy said that Alaska has become a premiere location to search for dinosaur fossils. McCarthy said that researchers have been flocking to the area ever since a footprint was discovered in 2005 in Denali National Park.
The researcher said: “It took several years of dedicated looking before the first footprint was discovered in Denali in 2005, but since that time hundreds of tracks of dinosaurs and birds have been found.”
McCarthy said that the fossils found during the most recent expedition could date back 20 to 30 million years.
Pat Druckenmiller, the museum’s earth sciences curator, said that he was amazed at how many fossils were discovered by McCarthy and his team.
Druckenmiller said: “This is the kind of discovery you would have expected in the Lower 48 a hundred years ago… We found a great diversity of dinosaur types, evidence of an extinct ecosystem we never knew existed.”
