Microscopic analysis showed that the grooves on the Göbekli Tepe skull fragments were deliberately made with a flint tool.
Notes on verification
Confirmed by peer-reviewed study (Gresky et al., Science Advances 2017) and corroborated independently by multiple science journalism outlets (Phys.org, Smithsonian, ZME Science, Archaeology Wiki), all consistent with the original microscopic analysis findings.
