The modified skull fragments found at Göbekli Tepe date to approximately 10,000 to 7,000 years ago.
Notes on verification
Peer-reviewed Science Advances study (Gresky et al. 2017) and DAI institutional sources confirm the modified skull fragments belong to the Pre-Pottery Neolithic period (9600-7000 calBC), which roughly corresponds to 10,000-7,000 years ago, though exact calendar conversion conventions vary slightly across sources.
