Notes
This bannerstone was found in Marion County, Indiana, where the Miami, Potawatomi, Wea, and Delaware tribes lived. This bannerstone likely dates to the Archaic period, which dates from 6000-1000 BCE.
Archaeologists are not 100% sure what bannerstones were used for, but it has been hypothesized that these were added to arrows, spears, or atlatls to help provide counterbalance and increase accuracy and power.
