These three bone artifacts were recovered during excavations by Kansas Historical Society archeologists at the Nulik site in Sumner County. It is unknown if these decorated bones had a functional or decorative use. The bones are incised with a series of diagonal and horizontal lines, zig-zags, and Xs. Remnants of drilled and polished holes on two of the bones may indicate their use an arrow shaft wrench, used to straighten a warped arrow shaft. The excavations in 1969 revealed a Great Bend aspect (ancestral Wichita) house and associated midden (refuse heap or mound).
