These four antler artifacts were found on sites in Illinois and Kentucky. They date to the Middle Woodland Hopewell culture. The lower three artifacts are barbed antler projectile points. They are much larger than later Mississippian period antler "arrow" points. Middle Woodland antler points were larger because they were used on the ends of spears that were propelled through the air with throwing sticks or atlatls. The segment of antler at top shows how the antler was grooved prior to snapping, trimming and drilling to finish a point. The antler point in the center is a cast. All three antler points were found on the Snyders site. The longest point measures 3 7/8 inches (9.9 cm) long.
