In lieu of an abstract, here is a brief excerpt of the content:

Matanzas Matanzas points are named after the West Matanzas site in the central Illinois River valley. other possible names or related points: Helton, Fishspear, Brunswick. Nearly 250 Matanzas points were found in Helton phase levels at the deeply stratified Koster site in western Illinois, and the type was subdivided into several varieties: Modal, Deep Side-Notched, Faint Side-Notched, Flared Stemmed, Straight Stemmed. The Faint Side-Notched variety may resemble Price Stemmed and Chesrow points, but the base is generally straight as opposed to concave. age: The points are well-dated to 6,000 to 5,000 .. (Helton phase) at the Koster site, 5,920 .. at the Barton-Milner site in north-central Illinois, 4,780 .. at the Murphy site in Dane County, Wisconsin, and 4,330 .. at the Crow Hollow site in the Kickapoo Valley of southwestern Wisconsin. distribution: These points are common in Illinois, Missouri, and eastern Iowa, although they are rare in the northern portion of the Upper Mississippi Valley. description: The points are small to medium spear-knife points. Blades are relatively thick, long and narrow with parallel sides that merge at a snub-point tip. They have short stems with shallow side notches, which are never deeper than they are wide. The blade of the Faint Side-Notched Matanzas merges with the stem forming a shallow concave curve. Bases are usually straight or slightly con1 cm 3 recto running foot | 49 cave and basal ears are small and round. Basal grinding occurs on nearly 60 percent of the specimens. Length: 4–6 cm/1.5–2.5 in. Width: 1.5–4 cm/0.5–1.5 in. material: Matanzas points are made from local chert, and heat-treating is common. references: Cook 1976; Justice 1987; Kuehn 1997; Morrow 1984; Munson and Harn 1966; Perino 1968; Stoltman 1997. 50 | middle archaic stemmed and side-notched points ...
