Secret History
The giant ball of rock has a radius of between four and five feet (1.2 to 1.5 metres) and is extremely iron rich. Semir Osmanagic discovered the 'stone ball' near the town Zavidovici in central Bosnia and Herzegovina and said it is the heaviest man-made ball in the world.
Dr Osmanagic had previously hit the headlines for his work on the supposed existence of ancient pyramids in the Visoko Valley, which he believes are hidden in plain sight as a cluster of hills. The phenomenon of stone balls has been linked with ancient civilisations around the world with the most famous being the stone spheres of Costa Rica. In total there are around 300, weighing up to 15 tonnes, which are believed to have been created by the now extinct Diquis culture, potentially making them up to 1,500 years old.
It is unclear how they were created but it is believed they were first sculpted from a local stone before being hammered and polished with sand.
If the huge stone in Bosnia is found to be made by human hands, it would be the largest man-made stone ball ever found - twice as heavy as the Costa Rican ones.
But there seems to be no proof that the 'sphere' is anything more than an unusual product of nature at the moment. These images actually reminds me of the Moeraki boulders in New Zealand.

..Promoted the Bosnian Pyramids which seem most likely to be a complete fake.
My friend even went there and without me galvanizing his opinion beforehand, concluded that he is extremely skeptical about how slowly they have excavated any structures there for the period of over 10 years now even with little funding, even if there was one spade in service.
He said 'it looks as if somebody put these artifacts there rather than dug them up', and there's some authoritative other researchers calling a fake on these. Klaus Dona one them as far as I remember. So just to bear that in mind and take the guy with a pinch of salt.
BUT, not to throw out a baby with the bath water because I can't see how he'd fake that one and squeeze it under a tree
Interesting (nonetheless!)
As much as I would like to travel on with this imaginary adventure...these balls are natural formations of sedimentary rock as you can see in the layering. The term for these balls are called concretions- [Link]
Can be round saucer shaped, random but there is often an iron oxide component to the minerals giving the often rust colored hue.
