These are some delicate leaf-shaped and elongated rhomboidal arrowheads from Northern Afghanistan. Such weaponry is not typical for the Neolithic cultures of this region, but becomes only important during the Bronze age. In fact, arrowheads are the only flint artifacts reported from the Bronze Age of Central Asia. They have been found together with rich bronze tools.
There are no full analogies to our arrowheads from a securely dated context. Similar implements in Central Asia are known from the Zaman-Baba and from the Murghab Oasis, the settlement of Sarazm, Tajikistan.
In 2003 Lee et al published the flint arrowheads from Altyn Depe site, Southern Turkmenia. Reviewing this publication gives a nice overview about this type of flint-tool after the “Stone Age”.
