The Bosnian Indiana Jones has come into contact with a giant stone sphere. Like the famous movie counterpart, this large object is also bringing excitement along with it. The stone sphere discovered in mid-March, 2016 in Bosnia may be the largest of its kind in the world, however there is much debate if the feature is man-made or natural. The stone ball was discovered in a forest in Podubravlje and has a radius of between 1.2 – 1.5 meters (3.9-4.9 ft.) Preliminary tests suggest that it could weigh over 30 tons, making it the most massive stone sphere in Europe.

A press release by Dr. Sam (Semir) Osmanagich, says that the materials have not yet been analyzed, however the “brown and red color of the ball point to very high content of iron.” With that in mind, his research has suggested quantities of 7,8 kg/c.c. of iron as a possibility – which would advance the weight of the stone sphere to over the estimate of 30 tons (which is based on a value of 5 kg/c.c.) That weight of the massive stone sphere could make it a contender for the heaviest stone ball in the World - surpassing those in Costa Rica (35 tons) and Mexico (40 tons).

Apart from the large size of the sphere, Dr. Osmanagich discussed what this discovery could mean for the perceptions of past civilizations in the press release:

“First, it would be another proof that Southern Europe, Balkan and Bosnia in particular, were homes for advanced civilizations from the distant past and we have no written records about them. Secondly, they had [advanced] 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 also be found in Bosnia.”

Signs of natural sedimentation are found over the sphere as: a layer of sandstone plates, then clay, soil, and vegetation.  Dr. Osmanagich asserts that “It takes tens, even hundreds of thousands of years for this sediment to form.” The Telegraph reports that “Dr. Osmanagich believes the sphere proves the existence of an advanced lost civilization dating back more than 1,500 years ago.”

There are critics of this hypothesis, including Mandy Edwards from the University of Manchester's School of Earth, Atmospheric and Environmental Sciences. Edwards has argued for a different explanation for the phenomena:

“The sphere in fact, may not be man-made at all. Describing the process of 'concretion' […] the sphere could have been formed due to precipitation of natural mineral cement within the spaces between sediment grains.”

Leaving the question of the origins of the stone sphere aside for the moment, similar stone spheres have purportedly been discovered by Dr. Osmanagich and his team “in twenty different locations, either shaped or, in some instances, made from different materials. We found granite stone balls in the Teocak village in northeastern Bosnia, volcanic stone ball near town of Konjic in middle Bosnia and sandstone stone spheres in many locations in western and middle Bosnia.”

Dr. Osmanagich said that there “used to be 80 of them in 1930s. In the meantime, some were taken by the river further down to the river Bosna, most of them have been destroyed in 1970s after rumors of gold being hidden in the middle of them, some were taken by locals and moved to their backyards. Only eight stone balls remained in what we established as Archaeological Park: Bosnian Stone Balls”. We’ve started promoting this location and it’s been visited by thousands of tourists every year.”

The press release that Dr. Osmanagich has been researching the ancient stone ball phenomenon for 15 years and has visited the “granite stone balls in southern Costa Rica, volcanic stone spheres in western Mexico, “coquina” stone balls in the small island in the Pacific - Isla del Caño, volcanic stone balls on Easter Island, some of them in Tunisia, and Tenerife on Canary Islands” and written about stone balls found in the Balkan region: northern Albania, province of Dalmatia in Croatia, and western Serbia.

Like the newly discovered sphere, there is much mystery surrounding the giant stone spheres of Costa Rica and their creation and purpose has been a hotly debated topic over the years. The spheres in Costa Rica were found while clearing a jungle in the 1940s. Almost all of them are made of granodiorite, a hard, igneous stone and many were seen as prized artifacts, although some were destroyed. Nevertheless, unlike the Bosnian counterpart, there has been little doubt that the Costa Rican spheres are anything but man-made.

These stone spheres are found naturally occuring in New Zealand. As large balls they are also rather easy to relocate.


I have experiance working as a repair welder. I had to prepare weld then it was sent to our machining department. In fact I mastered this skill while working on heavy machinery at this company, http://www.lnh.net/.  Stuff like this is easily made today,  I am not sure how ancients could have had a big enough lathe to turn this sphere or if it was had ground. I will say that for ferrite containing objects have to be worked to be that smooth and precise. These are pictures of it, https://search.yahoo.com/yhs/search?p=iron+ore&ei=UTF-8&hspart=mozilla&hsimp=yhs-002... I hope we can eventually find more on ancient sanding agents.

Unfortunately, the article cites the sphere as though it were a single anomaly. When in fact there are hundreds of these spheres all over Bosnia. Thus the article is less tha thorough and missing the all important PLURAL.


Far from being someone simply in search of fame, Dr. Osmanagich has worked for over a decade to uncover long hidden factual history including the Bosnian pyramid. But this is history which mainstream archaeology would rather ignore in favor of their ‘linear advancement theory’, hence their efforts to dismiss him.


Precisely, which is why many already distrust Dr. Osmanagichas. His past claims have exposed him as someone in search of glory.

What the archaeologist should have said is that the key here is to entirely excavate the stone. If the stone is entirely spherical (at present only one half is visible) then we have a reasonable hypothesis that the stone was worked by hand. If the stone is not entirely spherical then the question becomes entirely open.

A toothpick – the go-to little tool you select after a meal of corn on the cob, an object you absentmindedly chew on while listening to an unremarkable conversation, the piece of wood you carelessly toss away…this everyday item actually has a rather interesting history behind it.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
