After years of believing that unicorns were nothing more than mystical fairy tale creatures, researchers have definitively proved that they did exist -- though not as pretty horses with pearly white manes, wings and horns. Thanks to a newly discovered skull fossil found in the Pavlodar region of Kazakhstan, it's now known that the unicorn, or Elasmotherium sibiricum, roamed the planet roughly 29,000 years ago and looked more like a rhinoceros than a horse.  The study, published in the American Journal of Applied Sciences, also revealed that the unicorns stood about 6 feet tall, measured 15 feet long, and weighed around 8,000 pounds -- much larger than the horses that they were imagined to be.  The discovery was a shock to scientists, who initially thought that the creatures had gone extinct 350,000 years ago. "Most likely, the south of Western Siberia was a (refuge), where this rhino had preserved the longest in comparison with the rest of the range," Tomsk State University scientist Andrei Shpanksy noted in the research. Sadly, no magical flying abilities were discovered, but one never knows what future studies will reveal. Follow @Seventeen on Instagram.
