Giant camels roamed Arctic realms

(Continued)

Most of the protocamels that lived at lower latitudes in North America had teeth with high crowns suitable for grazing, says Mary Dawson, a paleontologist at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania, who was not involved with the work. But giant camels that roamed the Yukon about 3.5 million years ago-and presumably their slightly larger relatives living on Ellesmere Island at the same time-had low-crowned teeth best suited for grinding foliage, as today’s camels do. “These new findings tell us a lot,” she notes. “They open up the Arctic as a place of origin for the camels of today.”
