Semir Osmanagić (born 1 June 1960 in Zenica, SFR Yugoslavia), also known as Sam Osmanagich, is best known for promoting the pseudo-archaeological project related to the so-called "Bosnian pyramids". Osmanagić claims that a cluster of natural hills in central Bosnia and Herzegovina are the largest human-made ancient pyramids on Earth. Professional geologists, archaeologists and other scientists have concluded - after direct analysis of the site, its known history, and excavations - that the hills are common natural formations known as flatirons and that there are no signs of human construction involved.
