History
A large variety of prehistoric arrowheads, dart points, and spear points have been discovered. Flint, obsidian, quartz and many other rocks and minerals were commonly used to make points in North America. The oldest projectile points found in North America were long thought to date from about 13,000 years ago, during the Paleo-Indian period, however recent evidence suggests that North American projectile points may date to as old as 15,500 years. Some of the more famous Paleo-Indian types include Clovis, Folsom and Dalton points.
