Drawings of Angostura points from the Woodrow Heard site. All of these specimens are at the end of their use life and have been resharpened (items a, c, e, and f), broken by impact (item b) or snapped by use (items d, g, and h). The dots mark the extent of lateral edge grinding (from the base)—this technique, along with some parallel-flaking and the overall lanceolate form are technological holdovers from the Paleoindian lithic tradition. From Decker et al. 2000, Figure 172.
