The giant ball of rock (or) the ‘stone ball’ was discovered by Bosnian archaeologist Semir Osmanagic near the town Zavidovici in central Bosnia and Herzegovina.
The giant ball of rock has radius of between four and five feet (1.2 to 1.5 metres) and is extremely iron rich.
Semir Osmanagic said that it is the heaviest man-made ball in the world.
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.
Semir Osmanagic believes that the sphere proves the existence of an advanced lost civilisation dating back more than 1,500 years ago.
Dr Osmanagic, is known as "the Bosnian Indiana Jones" .
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.
According to his fellow researcher Dr. Sam Osmanagich,
the region used to have many more of the spheres well into the 20th
century. Many were apparently destroyed in the 1970s due to rumours
there was gold hidden in the middle of them.
