Lithic Technology

1. Lithic Technology Stone tool technology Simple, but not easy Good example of culture as a “mental template”

2. Lithic Technology Don Crabtree's Law “the greater the degree of final finishing applied to a stone artifact, whether by flaking, grinding and/or polishing, the harder it is to conclude the lithic reduction process which produced the stone artifact." Core Tool Technology Flake Tool Technology Blade Tool Technology

3. Lithic Technology The Atlatl A typical atlatl is shaped like a large 2 foot long crochet hook with finger loops at the end. The hook is inserted into a carved depression in the end of the spear or dart and the spear is thrown with a motion similar to throwing a baseball. This extension of the arm creates 2 1/2 times the force and results in being able to throw the spear 2 1/2 times the distance allowing for hunting at a distance. An atlatl dart is usually made of three major elements: the main shaft, foreshaft, and projectile point.

4. Microliths They are very small stone artifacts usually made from sections of small blades. They were too small to be used by themselves and would have been set into wooden or bone handles to make composite tools, some of which have been found

5. Polished Stone Axe (Celt) Mano and Metate with Bowl Stone Adze Ground and Polished Tools Made with tough, dense material such as basalt, quartzite, mudstone, etc. This material could not be shaped by chipping or flaking. Instead it was shaped by pecking and crushing the surface, then grinding and polishing.
