In the woodlands regions of North America, stone and quartzes were materials used extensively for ritual and utilitarian items. A bannerstone likely had a practical function as a counterweight on an atlatl, a long wooden shaft with a hooked end that was used to add power to a hunter’s arm when throwing a spear. The bannerstone’s wings may have provided balance. Bannerstones are often found far from stone sources, indicating they were part of a large trade network.
