Crystal Quartz and Fishtail Projectile Points: Considerations on Raw Materials Selection by Paleo-Southamericans

Abstract

The use of crystal quartz for making fishtail projectile points is reported in several sites in Uruguay. The widespread use of translucent crystal quartz by Paleo South Americans across suggests that raw material was not selected solely for its optimal flaking qualities and economical considerations. Other social and cultural considerations—esthetic or ideological?— suggest that its attractive glass-like translucency might also have been a factor in its choice.
