A test based on the pattern of use-related damage seen on projectile points from American Paleoindian sites is proposed to determine whether artifacts identified morphologically as points were in fact used as hafted projectiles. Thes test is applied to artifacts identified, based on Bordes' typology, as Mousterian points from two Iranian Mousterian sites (Warwasi and Bisitun). The results show that the ``Mousterian points'' from these sites do not have a breakage pattern consistent with a projectile point function.
