Siberian gold miners accidentally find ancient woolly rhino mummy with horn and soft tissues still intact

Gold miners in Siberia recently unearthed a mummified woolly rhino carcass with its horn and soft tissues still intact. The miners in the Sakha Republic, came across the carcass while excavating the site of a new quarry.

Photos of the remains, found in the Oymyakon District, appeared on the Russian social media site Telegram on Aug. 2.

Following the discovery, researchers at the North-Eastern Federal University (NEFU) in Yakutsk visited the site and recovered the rhino's horn. The rest of the mummified woolly rhinoceros ( Coelodonta antiquitatis ) will be excavated in the coming months, according to a translated statement from the NEFU .

"This is a truly unique find that will allow us to study the history of the region, its ancient fauna, climate and geological conditions in more depth," Anatoly Nikolaev, rector of the NEFU, said in the statement.

The permafrost in Siberia provides ideal conditions for the preservation of ancient creatures. The cold conditions mummify the remains, normally dehydrating soft tissues and locking them away in a frozen "time capsule."

The discovery of soft tissue is rare and allows scientists to get a far better insight into the life of the animal and the environment at the time it died compared to skeletal remains. It also provides a better opportunity to extract ancient DNA from the remains.

Maxim Cheprasov , senior researcher and head of the laboratory of the NEFU Mammoth Museum, said this is only the fifth time scientists have found a woolly rhino with intact soft tissues. "Until today, there was no such rare find in the collection of the Mammoth Museum," he said in the statement. "In the modern history of NEFU, this is the first such find."

Woolly rhinos mainly lived during the Pleistocene epoch (2.6 million to 11,700 years ago), first appearing about 300,000 years ago across northern Eurasia. As the last ice age ended, their range contracted until they only inhabited parts of Siberia — eventually going extinct about 10,000 years ago as a result of the changing climate and human activity .

NEFU researchers plan to study the horn before the rest of the remains are excavated. "According to morphological parameters, it belonged to a mature individual," Cheprasov said. "The exact biological age and sex of the animal will be determined after a comprehensive study of the carcass itself."

The woolly rhino discovery is one of several projects at the NEFU to learn about the ice age megafauna of Siberia. In June, researchers undertook a necropsy (animal autopsy) of a 44,000 year old mummified wolf pulled from the permafrost in Republic of Sakha.
