Coal miners in North Dakota unearth a mammoth tusk buried for thousands of years

BISMARCK, N.D. (AP) — The first person to spot it was a shovel operator working the overnight shift, eyeing a glint of white as he scooped up a giant mound of dirt and dropped it into a dump truck.

Later, after the truck driver dumped the load, a dozer driver was ready to flatten the dirt but stopped for a closer look when he, too, spotted that bit of white. Only then did the miners realize they had unearthed something special: a 7-footlong mammoth tusk that had been buried for thousands of years.

“We were very fortunate, lucky to find what we found,” said David Straley, an executive of North American Coal, which owns the mine.

The miners unearthed the tusk from an old streambed, about 40 feet (12.1 meters) deep, at the Freedom Mine near Beulah, North Dakota. The 45,000-acre (18,210-hectare) surface mine produces up to 16 million tons (14.5 million metric tons) of lignite coal per year. After spotting the tusk, the crews stopped digging in the area and called in experts, who estimated it to be 10,000 to 100,000 years old.

Jeff Person, a paleontologist with the North Dakota Geologic Survey, was among those to respond. He expressed surprise that the mammoth tusk hadn’t suffered more damage, considering the massive equipment used at the site.

“It’s miraculous that it came out pretty much unscathed,” Person said.

A subsequent dig at the discovery site found more bones. Person described it as a “trickle of finds,” totaling more than 20 bones, including a shoulder blade, ribs, a tooth and parts of hips, but it’s likely to be the most complete mammoth found in North Dakota, where it’s much more common to dig up an isolated mammoth bone, tooth or piece of a tusk.
