At one time, I showed an ancient skull with short, flat teeth. This condition comes from eating food, like roasted pine nuts and dried berries, ground between two stones. The grinding leaves rock particles in the food that work just like sandpaper. Dear Mr. Hickson, Thanks for showing us the bald headed Indian. The skull is no longer used in the presentation.
Federal law is the reason.
It had to be given to local Native American representatives for proper burial. The issue are understandable but what a wonderful visual example with which to teach more than 15,000 students over the years. My three sons made the files. We visited an archeological excavation late one summer on the east side of Pyramid Lake. A burial had been unearthed and the archeologist pointed out various parts of interest which were identified with numbered white cards.
