Clovis points dating

Post-Clovis cultures include the Folsom tradition, Gainey, Suwannee-Simpson, Plainview-Goshen, Cumberland, and Redstone.Each of these is commonly thought to derive directly from Clovis, in some cases apparently differing only in the length of the fluting on their projectile points.A Clovis projectile point created using bifacial percussion flaking (that is, each face is flaked on both edges alternatively with a percussor) Image courtesy of the Virginia Dept. Clovis points are the characteristically-fluted projectile points associated with the New World Clovis culture.

Clovis points are medium to large in size, ranging between 49mm to 179mm (2 to 7 inches) in length. The basal edge and sides of the halfting area are rubbed smooth and the flaking style is often overshot, causing the flake scars to extend well beyond the mid point of the blade.The lower edges of the blade and base are ground to dull edges for hafting.Clovis points also tend to be thicker than the typically thin later-stage Folsom points.The Clovis culture is a prehistoric Paleo-Indian culture, named for distinct stone tools found in close association with Pleistocene fauna at Blackwater Locality No. The Clovis culture appears around 11,500–11,000 uncal RCYBP (uncalibrated radiocarbon years before present), at the end of the last glacial period, and is characterized by the manufacture of "Clovis points" and distinctive bone and ivory tools.Archaeologists' most precise determinations at present suggest that this radiocarbon age is equal to roughly 13,200 to 12,900 calendar years ago.
