Researchers may have just scratched the surface of a major new dinosaur site nearly inside the Arctic Circle. This past summer, they discovered thousands of fossilized dinosaur footprints, large and small, along the rocky banks of Alaska’s Yukon River.
In July, the scientists from the University of Alaska Museum of the North embarked on a 500-mile journey down the Tanana and Yukon rivers; they brought back 2,000 pounds of dinosaur footprint fossils.
“We found dinosaur footprints by the scores on literally every outcrop we stopped at,” expedition researcher Paul McCarthy, of the University of Alaska Fairbanks, said in a statement. “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.”
The new prints along the Yukon River might date back 25 million to 30 million years earlier, McCarthy 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 explained in a statement. “In contrast, the tracks were so abundant along the Yukon River that we could find and collectas many as 50 specimens in as little as 10 minutes.”
The researchers say they have much more work ahead of them to understand and describe their findings. They are working with local villages and Native groups to coordinate future expeditions in the region.
