TOMSK, Russia, March 29 (UPI) -- Researchers thought the Siberian rhinoceros, also known as the "Siberian unicorn," went extinct some 350,000 years ago, but a newly excavated rhino fossil has been dated to 29,000 years ago, significantly altering the species' timeline.
The new evidence, published in the American Journal of Applied Sciences, suggests early humans lived alongside -- and potentially hunted -- the Siberian unicorn.
