Projectile Points

Projectile points are a category of pointed, bifacial stone artifacts that were used as arrowheads, spear points, and harpoon points for thousands of years; they are distinguished from other types of stone tools such as drills, scrapers, and knives by their distinct forms. They changed over time due to trade, how the point was used, influences from other cultures, and the available stones, among other reasons. Archaeologists tend to classify points through typologies, which group the artifacts into types based on shape, size, and age. By grouping them in this way, we can study not only how technology changed over thousands of years, but can also learn about trade, mobility, hunting, and diet.
