Forensic techniques used to study rock art

University researchers in England are using forensic techniques to study hand stencils found in prehistoric rock art.

To solve the problem, scientists adopted a forensics technique to yield more definitive results. Scientists believe the new analysis strategy can sex 40,000-year-old hand stencils with 90 percent accuracy.

“The problem with focussing on hand size and finger length is that two different shaped hands can have identical linear dimensions and ratios,” Patrick Randolph-Quinney, a forensic anthropologist at the universities of Central Lancashire and Witwatersrand, said in a news release. “To capture shape, we applied geometric morphometrics, a technique used in forensic studies that had never been tested on hand stencils before.”
