Large stones had been placed on his arms and legs, which were crossed to keep the remains in place.
Excavation leader Steven Birch said it was clear the man was carefully buried, though the team members don’t know why he was brutally killed.
“It’s very exciting in the fact that we’ve identified a projectile that hit a human target, which tells us definitively that we found the battlefield,” Sivilich said.
These are relatively low energies; the maximum distance traveled is estimated to be 22 cm in air and 0.27 mm in body tissue.
Under very hot temperatures — greater than 100,000,000 Kelvin (179,999,540.6 F) — the helium nuclei begin to fuse, first as pairs into unstable 4-proton beryllium nuclei, and eventually, as enough beryllium nuclei blink into existence, into a beryllium plus a helium.
The end result: Atoms with six protons and six neutrons — carbon.
The fifth injury is thought to have come from a larger weapon to the top of the skull.
Radiocarbon dating indicates that he was killed some 1,400 years ago.
