Moscow: The 'Siberian unicorn' - an ancient rhinoceros species thought to have gone extinct 350,000 years ago - may have found its last refuge as recently as 29,000 years ago in Kazakhstan, scientists say.

These conclusions were made from the fossilised skull of Elasmotherium sibiricum or 'Siberian unicorn' - a Siberian rhinoceros, found in the Pavlodar Irtysh region of Kazakhstan. "The skull is well preserved. There are some cracks but no trace of pelletisation, gnawing and exfoliation," researchers said.
