A mysterious wooden statue covered in undeciphered markings is 11,000 years old, according to new tests -- or 1,500 years older than previously believed. That makes the Shigir Idol the oldest known wooden sculpture in the world, the Siberian Times reported. The idol is more than twice as old as the Great Pyramid of Giza, three times older than the ancient city of Babylon, and five times as old as Al Khazneh, the most famous of the ruins in the ancient city of Petra.

To confirm the statue's age, seven "minuscule" samples of wood were sent to Germany for analysis by accelerated mass spectrometry, the Siberian Times reported.
