Elasmotherium.

The elasmoterio (Elasmotherium, gr. "Flat Siberian beast") is an extinct species of mammal Perissodactyla Rhinoceros family.

 It was a huge Asian rhino could be the origin of the legend of the unicorn, it had a single horn 2 meters long, sharp and exceptionally thick, from the merger of the usual two rhino horns. Because of this, it is also often called giant unicorn. 

The elasmoterios disappear from the fossil record in the late Pleistocene, about 10,000 years ago, along with much of the megafauna of the Northern Hemisphere, so this is considered as the most probable date of its extinction.However, some argue that some populations could survive a few millennia,leading to some beasts of folklore from the steppes of Eurasia.

 Possible mythological beasts inspired by this animal that have been identified, apart from the European unicorn, is a huge black bull with a single horn front.
