Elasmotherium sibiricum, sometimes referred to as the Siberian unicorn, had a horn likely multiple feet long. Only partial remains have been found.
It looked more like a rhinoceros than a horse, weighing about 9,000 pounds. It was thought to have been extinct for more than 350,000 years. But dating of a fossil found in Kazakhstan has recently proven a “unicorn” was still alive 29,000 years ago. The research results were published in the American Journal of Applied Sciences by scientists at Tomsk State University in Russia.
