Photos: Duck-Billed Dinos Found in Alaska

Researchers have uncovered a newfound species of duck-billed dinosaur in Alaska. It's unclear how the 30-foot-long (9.1 meters) herbivore lived at such a northern latitude, but it likely experienced both snow and long, dark winters, the researchers said.  [Read the full story on the hadrosaur from Alaska]

Duck-billed dinos of Alaska

About 69 million years ago, Earth's climate was warmer and Arctic Alaska was covered in trees. But it was still cold — about 43 degrees Fahrenheit (6.1 degrees Celsius) — and likely snowed during the hadrosaurs' time there. (Image credit: Copyright James Havens)

At the Liscomb Bone Bed, which sticks out some 200 feet (60 m) along this bluff, a paleontologist searches for dinosaur bones. Researchers have found almost 10,000 bones, belonging mostly to juveniles of the species. (UAMN Photo courtesy Pat Druckenmiller)
