These weren't accidents of nature. They weren't the work of predators or geological processes. They were jewelry — deliberately crafted personal ornaments, worn on human bodies, in Ice Age South America. Using cutting-edge technology including synchrotron X-ray microtomography, scanning electron microscopy, and UV photoluminescence imaging, an international team of researchers from Brazil, France, and the United States proved beyond reasonable doubt that these objects were shaped by human hands — on fresh bone, before burial, before fossilization.
