COVER Projectile points of the prehistoric Clovis complex of North America are characterized by their lanceolate shape, concave base, distinctive basal flute, and basal edge grinding. The large point in the middle shows the distinctive outrepassé flaking pattern (broad flakes that extend across the width of the point) often found on Clovis points and other bifaces. See page 1122.
