Giant Structure Made of Mammoth Bones Discovered

A structure built by Paleolithic humans 25,000 years ago, when the Ice Age was at its harshest, has been discovered. It is located on the steppe plains, 300 miles (482.803 km) south of Moscow. It is a circular structure 40 feet (12.192 meters) in diameter, made from the bones of more than 60 woolly mammoths. All the mammoth-bone buildings found until now have been small, so none of them can compare to this find. What purpose it was built for remains unknown. Perhaps it was used in place of a refrigerator.
