Resumo

In 1903 C. V. Hartman excavated archaeological materials in Costa Rica for Carnegie Museum and also purchased several local collections. In June 1950 the unpacking of a portion of the collection not reported by Hartman (1907), disclosed a fluted projectile point of dull black flint (Figs. 88, 89) with these measurements: length, A to B, 58 mm.; width, C to D, 32 mm.; maximum thickness, 5 mm. The point was made from a curved flake so that one face exhibits the fluting while the other retains the smooth, unworked original surface. The sides of both faces exhibit carefully controlled secondary chipping. The basal edge and the edges from C and D toward the base have been smoothed, either by intentional grinding or by the wear of successive rehaftings. Basal thinning is pronounced on both faces.
