Agate Basin Lanceolate Point
Chapman (1975:241-2) notes that Agate Basin Lanceolate points are found throughout Missouri and specifically notes that examples had been documented in Missouri at the sites of Arnold Research Cave, Rice Shelter, Rodgers Shelter and the Dalton Site. The diagnostic feature of this artifact is the fact that the blade is unnotched, long and slender. Chapman notes that length ranges from 50 to 130 mm with the average of 100 mm; thickness is typically 8 mm. DeRegnaucourt (1991:17 - 19) notes that this artifact type is rare in the Ohio and summarizes measurements from two specimens: Length = 71 to 73 mm, width = 23 to 28 mm, thickness = 7 to 8 mm and weight = 16.2 to 17.4 grams. Radiocarbon dates at the type site in Wyoming range from 8480 to 7400 BC (DeRegnaucourt 1991:17). Morrow (1984:18) notes that Agate Basin points are common throughout the Great Plains and Upper Midwest - including Iowa. Sandstrom and Ray (2004:44) prefer the designation as "Packard" for this point type and cite a radiocarbon date of 7466 BC +/- 193 from Packard site in Oklahoma.
