Apparently not much news happening on Christmas Day. However, I figured it was a short "introduction" to the topic.
Points, frequently made by chipping types of flint, were fastened to the business end of spears, darts and arrows.
Also made of antlers, bones and copper in prehistoric times, points changed somewhat over the centuries, but some styles were used across much of North America, according to a guide produced by the Mississippi Valley Archaeology Center.
Archaeologists have noted some regional variations in point styles but have not found much evidence of individual expression, the guide said. “Point makers in general were conformists and manufactured tips according to prevailing culturally accepted styles,” the guide explained.
