YAKUTSK, RUSSIA—Scientists at North-Eastern Federal University (NEFU) have autopsied the remains of a three-month-old female dog thought to have died during a landslide near the Syallakh River some 12,450 years ago. (Two twigs in her stomach suggest that she tried to grab onto nearby plants with her teeth.) The puppy, whose fur, skin, bones, and internal organs are intact, was discovered in permafrost by two men who were looking for mammoth tusks in an area where hikers have found stone and bone tools and weapons. Was the puppy an early domestic breed? “Our task is to estimate the preservation of the ancient animal tissues at the macro and micro level. What is of real interest is the fact the animal has a completely preserved carcass, which is unique by itself, with nothing like it in the world. Although the tissues are mummified, they have no post-mortem decomposition, as it usually happens with biological material,” Darima Garmaeva of the NEFU Medical Institute told The Siberian Times. Members of the dog research project will return to the site with archaeologists this summer to look for evidence of early dog owners.
