14 DAY TRIAL // Paleontologists working with the University of Alaska Museum of the North say that, while walking along the banks of Alaska's Yukon River this summer, they pinned down thousands of dinosaur footprints.
The footprints formed when the ancient creatures stepped in mud. In time, sand filled their tracks and the footprints became fossilized, Live Science tells us.
Researcher Paul McCarthy explains that, in some areas, the footprints were so close to one another that he and his colleagues were able to pin down several dozens in a matter of minutes.
“We found dinosaur footprints by the scores on literally every outcrop we stopped at,” Paul McCarthy said in a statement.
“The tracks were so abundant along the Yukon River that we could find and collect as many as 50 specimens in as little as 10 minutes,” he added.
Preliminary investigations have revealed that the prints are 95 – 110 million years ago. By the looks of it, they belong to many different species.
Researchers plan to further analyze them, and try to figure out what the ecosystem these creatures were part and parcel of used to look like.
