elasmotherium sibiricum

Weighing up to 3,500kg, Elasmotherium sibiricum—an extinct hairy rhino popularly known as the “Siberian unicorn”—was thought to have disappeared as long as 200,000 years ago. An updated fossil analysis suggests this formidable species was still around some 39,000 years ago, and that Ice Age conditions, not human hunters, contributed to its demise.
