| Clovis spearpoints, such as this one from northeastern Utah, are among the oldest stone tools known in the Americas. The oldest Clovis spearpoints in North America date to about 11,500 years ago. Native Americans attached such points to shafts, making spears that could either be thrust directly at animal prey or thrown using atlatls (spear-throwers). Archaeologists believe the spearpoints were also used as multipurpose cutting tools. |
