This paper discusses geometrics from Tall-i Mushki, which is the oldest Neolithic site in the Marv Dasht Basin, Southwestern Iran. The geometrics can be divided into two types: broad geometrics and narrow geometrics. Patterns of impact fractures on them caused by use suggest that those of the broad type were used as transverse arrowheads and those of the narrow type were used as transverse arrowheads and barbs. At Tal-i Jari B, which chronologically followed Tall-i Mushki, the number of geometrics has decreased and narrow geometrics have disappeared. This suggests that arrow technology became simple. This phenomenon was probably caused by introduction of domesticated animals during the Tall-i Jari B phase.
