Tens of thousands of years ago, unicorns did, in fact, exist. They were just more hideous than you’d ever imagine. In real life, the Siberian unicorn looked more like a giant, hairy rhino than a Lisa Frank horse. It fed its six-and-a-half-foot, four-ton frame by eating lots of grass. The discovery of real unicorns isn’t new, but according to a new study in the American Journal of Applied Science, they roamed the Earth much more recently than previously thought.
