This boatstone fragment was recovered from a multicomponent site in Montgomery County and donated to the Kansas Historical Society in 1964. The camp site was occupied periodically from the Archaic Period and the Early and Late Ceramic Periods. This boatstone would have dated to the earlier time occupations. Boatstones are thought by archeologists to have been used as atlatl weights. The boatstone would have been tied to the atlatl utilizing the central medial groove along the keel. It would have aided the atlatl (spearthrower) in throwing the spear and dart further and faster. The boatstone may have decorative radiating lines on each side of its existing end.
