The discovery of the man sat in the lotus position has sparked a forensic investigation into the unknown religious devotee - with experts' initial evaluation suggesting the mummified remains are at least 200 years old.

The human relic, which had been preserved in animal skin, was found this week in Songinokhairkhan province, according to Mongolia's Morning Newspaper.

Investigators are now studying the remains in the capital Ulaanbataar.

In Koh Samui, Thailand, a mummified monk wearing sunglasses - Luong Pordaeng, who died in 1973 – provides an unusual tourist attraction.
