Researchers are trying to determine whether an 18,000-year-old puppy found in Siberia is a dog or a wolf.
The canine - which was two months old when it died - has been remarkably preserved in the permafrost of the Russian region, with its fur, nose and teeth all intact.
DNA sequencing has been unable to determine the species.
Scientists say that could mean the specimen represents an evolutionary link between wolves and modern dogs.
Researcher Dave Stanton at the Centre for Palaeogenetics in Sweden told CNN the DNA sequencing issue meant the animal could come from a population that is a common ancestor of both dogs and wolves.
Modern dogs are believed to be descendants of wolves, but there is debate over when dogs were domesticated.....snip~
