ABSTRACT
The 10 pecking stones in the Tutu collection are (usually elongate flattish or subspherical) cobbles whose perimeters exhibit signs of intensive crushing and battering that is indicative of use as a hammerstone or pecking implement. It seems likely that these objects were used as pecking stones in the production of ground stone artifacts. Unfortunately, 8 of these 10 artifacts were recovered from surface contexts. The pecking stones are described individually below:
• 31-BII-C-12: Flat cobble of blue-grey volcanic material with a few phenocrysts of white feldspar. Extensive cortex on one side, no cortex on other side. Evidence of pecking on one end and one side. Length = 9.15 cm; width = 6.28 cm; thickness = 2.49 cm.
