The animal was buried in a lump of frozen mud in Russia, its fur, whiskers and body fully intact. Scientists are studying its DNA to understand whether it is a dog or a wolf.

An 18,000-year-old puppy buried for centuries in a lump of frozen mud was unveiled on Monday by scientists who hope it can help bridge the connection between dogs and wolves.

The puppy, which was male, was discovered 18 months ago, preserved in a layer of permafrost in Siberia’s Far Eastern reaches, according to Dave Stanton, a research fellow at the Center for Palaeogenetics in Stockholm and one of the scientists who examined its DNA.

The fur, skeleton, teeth, head, lashes and whiskers of the pup, named Dogor, are still intact, he said. But scientists don’t know whether it is a dog or wolf. Dr. Stanton said more DNA research would be conducted in the coming months.
