Small scrapers are also included. In North American archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites. They provide useful clues to the human past, including prehistoric trade. 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. Largest point is 2"L, smallest is .5"L. Display case measures 12.25"W x 16.25"L
