My big mistake with radiocarbon dating in Colorado
I was working on a dig site near Durango a few months ago and kept getting weird dates on some bone fragments. They were way older than they should have been based on the layers around them. After pulling my hair out for a week, a buddy told me to check if the bones were boiled by ancient people. Sure enough, a quick microscopic look showed collagen damage from boiling, which can mess up the carbon dates. Has anyone else run into cooking contamination throwing off their results?
