A mysterious giant spherical rock was discovered in a Bosnian forest.
Archaeologist Semir Osmanagic says it could be the oldest man-made stone sphere in the world.
"I've been researching prehistoric stone ball phenomenon for 15 years," he wrote in March. "By the mid of March 2016, it became obvious that the most massive stone ball in Europe has been discovered. Name of the location is village Podubravlje."
It has a radius of between 4 and 5 feet, with an “extremely high” iron count.
Osmanagic theorizes the stone points to an advanced lost civilization dating back around 1,500 years:
First, it would be another proof that Southern Europe, Balkan and Bosnia in particular, were home for advanced civilizations from distant past and we have no written records about them.
Secondly, they had high technology, different than ours.
Finally, they knew the power of geometrical shapes, because the sphere is one of the most powerful shapes, along with pyramidal and conical shapes. No wonder, that pyramids and tumulus phenomena can be found in Bosnia.
A lecturer at the University of Manchester School of Earth, Atmospheric and Environmental Sciences told the Daily Mail the spherical stone may be a result of the geological process of concretion.
The phenomena occurs when rock is shaped by spheroidal weathering from precipitation of natural mineral cement within the gaps between sediment grains. This frequently results in a spherical shape, similar to the Koutu boulders in New Zealand, according to Phys.org.
Osmanagic is known as “the Bosnian Indiana Jones” and gained publicity in 2005 when he claimed a group of hills in Bosnia’s Visoko Valley were actually ancient pyramids connected by a network of underground tunnels.
Although some mocked his claims, the Bosnian government believed him enough to fund an excavation.
“We were told the world was laughing at us ... but there is no government in the world that should stay quiet on things which are positive,” said Bosnian Prime Minister Nedzad Brankovic at the time.
President of the European Association of Archaelogists Anthony Harding called the excavation was “a total absurdity,” according to The Telegraph.
“There is some genuine archaeology on the hill and I’m told it’s medieval, possibly Bronze Age or Roman. But the speculation that there could be a 12,000-year-old structure beneath is complete fantasy and anyone with basic knowledge of archaeology or history should recognize that,” said Harding.
