It’s important to include some context to this.
Prior to the arrival of Europeans to the east coast, the number one cause of death for Native Americans was starvation. And there are strong indications that some of the tribes did resort to cannibalism now and then.
That was my question. Were the marks consistent with sharpened steel implements or stone? If stone, then the possibility exists that the remains could have been recovered from the Indians and given a proper burial.
And if stone, the premise of the article is suspect and possibly an attempt to besmirch colonists long dead.
