An analysis of Folsom projectile point resharpening using quantitative comparisons of form and allometry

Handaxe reduction and its influence on shape: An experimental test and archaeological case study

“…Intensity of reduction on flaked stone tools is an important component of variation in Middle and Late Palaeolithic technologies (Buchanan, 2006;Kuhn, 1992Kuhn, , 1994, but its role in determining or affecting the shape of Acheulean bifaces is debated. Understanding and controlling for reduction intensity in the Acheulean is a critical hurdle to interpreting variation in biface morphology (Nowell, 2002;McPherron, 2000).…”

A geometric morphometrics-based assessment of blade shape differences among Paleoindian projectile point types from western North America

“…The samples of Folsom and Plainview points used in this study differ from the samples used by Buchanan (2006) and . Buchanan (2006) focused on Folsom points from the Southern Plains made only of Edwards chert in order to measure shape change with distance from source. This restriction was removed in the present study and seven points made of raw materials other than Edwards chert were added to the sample.…”

“…This restriction was removed in the present study and seven points made of raw materials other than Edwards chert were added to the sample. Seven Folsom points used by Buchanan (2006) were excluded from the study reported here because they were insufficiently complete. also employed a number of incomplete specimens in their analysis of Plainview points.…”

“…The point areas were taken from Buchanan (2005Buchanan ( , 2006 and . We used Buchanan's (2005Buchanan's ( , 2006 and Buchanan et al's (2007) point areas rather than the centroid sizes generated by the GPA because Buchanan (2005Buchanan ( , 2006 and included landmarks demarcating the basal portion of points. The base is important to take into account when assessing point area because it ranges from concave to convex in shape both among and within types.…”

“…We carried out one DFA with each group of points divided into ''small points'' and ''large points'', and one with each group of points divided into ''small points,'' ''medium points,'' and ''large points''. As in the analyses that focused on allometric effects, the point areas were taken from Buchanan (2005Buchanan ( , 2006 and .…”
