The researchers are now studying how this creature was able to survive so much longer than many of its kind.
“Most likely, the south of Western Siberia was a refúgium [refuge], where this rhino persevered the longest in comparison with the rest of its range,” Andrei Shpanski, a paleontologist at Tomsk State University, told Phys.org. “There is another possibility that it could migrate and dwell for a while in the more southern areas.”*3
Unfortunately, despite its sizable horn, the “Siberian unicorn” looked more like a rhinoceros than the mythical creature its nickname refers to. It was about 6 feet tall, 15 feet long, and weighed about 9,000 pounds, making it more comparable to a woolly mammoth than a horse.
