Using a new method, researchers concluded from DNA evidence that the 20,000-year-old dear tooth pendant’s owner, and perhaps creator, was an Ancient North Eurasian woman.

To find alternatives, the researchers submerged animal bones discovered at Stone Age sites in four gentler chemicals to test the results. While two appeared to damage the bones, the others seemed to stop at removing surface-level sediments and chemicals, such as DNA left behind by sweat. They washed the artifacts and exposed them to sodium phosphate at different temperatures and recovered the most DNA from the hottest temperature, 194 degrees Fahrenheit, just shy of boiling. Ultimately, the pendant from Denisova yielded the best mitochondrial DNA sample, the one the researchers tied to a 19,000-year-old female.
