Intact prehistoric wolf head found in Siberian permafrost by locals hunting for mammoth tusks

MOSCOW ‚ÄĒ The first intact adult head of an Ice Age wolf found preserved in permafrost for 40,000 years is being analyzed by scientists.
Still covered in thick fur and sporting a vicious-looking set of fangs, the 15-inch head was found on the Tirekhtyakh river by locals hunting for mammoth tusks in the remote Siberian region of Yakutia last year.
Now Russian and Japanese scientists hope that the find will help them learn more about an ancient predator that roamed Europe and Asia alongside the woolly rhinoceros and mammoth.
The soil in most of Yakutia remains frozen all year round, preventing ancient tusks and carcasses from decomposing. Specimens have been emerging ever more frequently as climate change gradually thaws the permafrost.
Well-preserved infant cave lions have been previously discovered nearby.
The mammoth tusk industry, which has been booming after China banned the carving of elephant ivory, has become the main source of palaeontological discoveries in the region, and the tusk hunters gave the head to Protopopov. at the academy
Unsure if it was thousands of years old or just a few hundred, he passed a sample to the Museum of Natural History in Stockholm, where the head was found to date to 40 millennia ago. It was also discovered the wolf was between two and four years old when it died.
Researchers at the Jikei University School of Medicine in Tokyo performed tomographic scans to map muscles and tissue in the specimen.
Both the Swedish and Japanese facilities will continue to study the DNA and internal anatomy of the head, which includes a fully preserved brain.
‚ÄúThere were lots of wolves but we don‚Äôt know much about them.‚ÄĚ Albert Protopopov
Working with Russian scientists, they plan to compare the animal‚Äôs genetic make-up and morphology to the wolves of today.
It is not clear whether the ‚ÄúPleistocene wolf‚ÄĚ was larger than contemporary wolves, but its jaws were definitely stronger. ‚ÄúThey could kill bigger animals ‚ÄĒ probably the biggest was a bison,‚ÄĚ Protopopov said.
‚ÄúIt‚Äôs important for science because wolves in the Pleistocene were broadly dispersed like cave lions,‚ÄĚ he said. ‚ÄúThere were lots of wolves but we don‚Äôt know much about them.‚ÄĚ Several species of wolves lived during the Pleistocene ice age, including the celebrated dire wolf in the Americas.
Based on bones found in Siberia, both dogs and modern wolves are believed to have split off from a wolf ancestor at least 27,000 years ago.
Siberian huskies carry some genes of this ancient wolf even today. The head of the Ice Age wolf was unveiled at a woolly mammoth exhibition in Tokyo last week. It also featured a new Siberian cave lion cub specimen named Spartak, which weighs less than 2lb. It is in near-pristine condition, like the wolf head, and will be compared to modern lions. Scientists in Yakutia and Tokyo also hope to one day clone a woolly mammoth from tissue discovered in the Siberian permafrost, although such a project is not possible with current techniques.
