”A team of researchers with the German Archaeological Institute has found long, deliberate marks carved into ancient skulls found at the Göbekli Tepe dig site…
The team determined that the skull fragments they found with the unique marks on them belonged to just three individuals—each had deep straight-line grooves carved into the bone and one of them also had a hole drilled through its top…
Because it is not clear why the grooves appeared only on three skulls, the researchers were left to generate theories—they believe one of the likeliest possibilities is that the grooves were made to hold cords in place while the skull was hoisted onto a pole using the drilled hole—possibly as a way to scare off enemies.” – Skull fragments with carved long, deliberate lines found at Gobekli Tepe
