Clearly an early Indian relic, and must be returned to a local tribe for proper burial.
Never to be chewed on by a dog!
Major fines pending.
Near Seattle a few years ago they found an old prehistoric camp - tools dating to 10,500 years ago IIRC. They had photos of them, looked like a bunch of plain old rocks to me! When I drive by the place (near a creek, meadows, etc.) it is pretty cool to imagine them, and how times have changed.
Sure glad I don’t have to worry about hitting a mammoth while driving though!
