At first glance, Chatters thought it might belong to an early pioneer or trapper. But the teeth were cavity-free (signaling a diet low in sugar and starch) and worn down to the roots—a combination characteristic of prehistoric teeth. Chatters then noted something embedded in the hipbone. It proved to be a stone spearpoint, which seemed to clinch that the remains were prehistoric. He sent a bone sample off for carbon dating. The results: It was more than 9,000 years old.
