This object appears to be a Native American bannerstone, specifically a winged or bow-tie variant dating back to the Archaic period (6000–1000 BCE). [1]Function and BackgroundAtlatl Counterweight: These ancient artifacts were meticulously carved by Indigenous peoples in eastern North America to serve as weights for an atlatl (spear-thrower). The weight added balance, increased the thrower's leverage, and dramatically improved the speed and velocity of the launched spear. [1]Craftsmanship: They were painstakingly sculpted from various types of sedimentary, metamorphic, or igneous stone. The maker used pecking, grinding, and polishing techniques to reveal the natural grain and beauty of the rock. [1, 2]Centrally Drilled Hole: If you flip the object or look closely at the interior curvature, you will see a clean, drilled hole going straight through the center. This opening allowed the stone to be slid and secured onto the wooden shaft of the spear-thrower.Ceremonial Value: While highly functional, many beautifully polished or oversized bannerstones likely held deep ceremonial significance, serving as status symbols or ritual objects within nomadic communities
