Miners Unearth 50,000-Year-Old Caribou Calf, Wolf Pup From Canadian Permafrost

Dawson City, Yukon – the land known for its role in the Klondike Gold Rush of the late 19th century – today is dominated by the forest, but the area was freezing without trees some Fifty thousand years ago.

Alongside mammals whose distant descendants still inhabit Arctic territory today, long-extinct species, including woolly mammoths and western camels, roamed the area, navigating the arid climate with mixed success.

Gold miners in Canada have discovered the remarkably well-preserved remains of a caribou calf and wolf pup (shown) that each lived more than 50,000 years ago. The wolf pup’s remains were complete, with its head, tail, paws, skin, and hair


Now, two of these Ice Age animals, a caribou calf and a wolf pup, have emerged with their hair, skin and muscles almost completely intact from the Yukon permafrost, or permanently frozen earth, thousands of years after their deaths.

The Guardian’s Anthea Lacchia writes that the mummified animals, which were unearthed by gold miners back in summer 2016, made their public debut last Thursday. Both have been radiocarbon-dated to more than 50,000 years ago, making the state of their preservation all the more impressive.

As paleontologist Grant Zazula tells the The Canadian Press, the specimens are amongst the oldest examples of mummified mammal soft tissue ever found, and the wolf cub is the only one of its kind yet to be unearthed.

According to BBC News, the wolf is the better-preserved of the two specimens, retaining everything from its fur to its tail and and curled upper lip. Researchers believe the pup died when it was roughly eight weeks old.

Officials say the ancient caribou dug up from a site containing an 80,000-year-old volcanic ash bed now stands as one of the oldest examples of mummified mammal tissue in the world. Only the front half of its body remained intact

The caribou is in worse condition, with only its head, torso and front limbs intact, but like the wolf, it provides a singular example of mummified animal skin, muscle and hair.

CBC News reports that the caribou was found in a gold mine owned by local reality TV star Tony Beets in June 2016. The calf was buried in permafrost near an 80,000-year-old bed of volcanic ash, which Zazula says originated from Ice Age-era eruptions. One month later, another local miner chanced upon the wolf cub, which he initially identified as a deceased dog.

This isn’t the first time the Canadian permafrost has yielded a spectacular mummified find. About 30 years ago, two miners uncovered the partial remains of a roughly 26,000-year-old Yukon horse, but as Zazula tells the Canadian Press, no significant soft-tissue specimens had emerged since.

The discoveries hold special significance to the Tr’ondëk Hwëch’in, upon whose land they were discovered. Both animals will be on display for the rest of the month, before being moved to the Yukon Beringia Interpretive Centre in Whitehorse. The mummified wolf is shown

“We sometimes get jealous because in Siberia, … it seems like they find a new woolly mammoth carcass every summer,” he notes. “But we never seem to find those in the Yukon or Alaska.”

It’s true that the Siberian region of Yakutia is renowned for its seemingly endless string of singular discoveries: At the end of August, researchers chanced upon the mummified remains of a 30,000- to 40,000-year-old baby horse.

And, last November, a Russian local discovered the frozen remains of an extinct cave lion cub that died up to 50,000 years ago.

Thanks to the Yukon caribou calf and wolf cub, however, Canadian scientists finally have a pair of specimens that rival any Siberian finds.

The Canadian Press reports that researchers’ next step will be genetic testing designed to provide insights on the ancient animals’ diets, which in turn reveal information about their Ice Age environment, and analysis of the pair’s bone composition.

For now, the mummified specimens will remain on display at Dawson City’s Dänojà Zho Cultural Centre. Eventually, the remains will be incorporated within an exhibition at the Beringia Interpretive Centre in Whitehorse.


“When you look at fossil bones, that’s one thing,” Zazula concludes. “But when you actually see a whole animal from an ancient time, it brings that ancient time to life.

It just makes you ponder about the amazing changes that have happened in the environment, the climate and the animal community since that time.”
