"the trophy heads excavated but unreported in the 1930's are being dug out of museum basements."
Really? I hadn't heard about that. But then, my last anthropology class was in 1976.
Do you know of a good link?
I know of a good book "Prehistoric Warfare in the Southwest" but I can't recollect the name of the author. (Sorry, but that's the best I can do.)
