The US team don't think so. Their evidence centres on the dense vertical and horizontal lines at the back of the skull - these are layers of resin, poured in by the mummifiers after they had removed Tutankmaun's brain.
Because the bone fragments stick out from the resin into the brain cavity, and are not covered by the resin, they must have come to rest there after the resin was added. That's after Tutankhamun died. So these bones are nothing to do with his death. Or are they?
