Clovis points are the diagnostic projectile point associated with the North American Clovis culture. They date to the Paleo-Indian period around 13, 500 years ago. They are named after the city of Clovis, New Mexico, where examples were found in 1929 by local men who eventually encouraged Edgar Billings Howard to visit. This first visit occurred in August 1932 while Howard was digging with a joint team from the Philadelphia Academy of Natural Sciences and the University of Pennsylvania at Burnet Cave in the Guadalupe Mountains, New Mexico. Clovis points are often found archeologically associated with the remains of Pleistocene megafauna. Clovis points are thin, fluted projectile points created using bifacial percussion flaking (that is, each face is flaked on both edges alternatively with a percussor). To finish shaping and sharpening the points they are sometimes pressure flaked along the outer edges of the flint, chert, jasper, or other stone of conchoidal fracture. Clovis points are characterized by concave longitudinal flutes (grooves) on both faces from the base one third or more up its length toward the pointed tip. Archaeologists think the groove permitted the points to be fastened (hafted) to wooden spears or dart shafts or foreshafts that would have been socketed onto the tip end of a spear or dart, or, points hafted as a knife whose handle could have served also as a removable spear/dart foreshaft.
