Experts from a US museum believe it could be one of the oldest examples of advanced surgery. The Museum of Osteology in Oklahoma said the skull is reported to have been that of a man who was injured in battle before undergoing surgery to implant a piece of metal in his head to repair a fracture.
It's no one bothered by the fact his skull is massive? And before you say they elongated his skull with ropes, go and check more recent procedures, the skull thines on the top, like a cone head.
This guy skull was ancient aliens big, because I doubt that was a warrior with macrocephaly.
