You can try to infer how these people died. You might have some trauma fractures here, and you might say, okay, that was a violent death. You might look at their teeth to think about the type of things they might have eaten or their general health. You might look at the tools that are buried near them. This right over here, these are Paleolithic arrow, I guess, spearheads or tools right over here. Paleolithic is defined by more of these harder edges. You have Neolithic tools, which have more of these smoother edges.
