Stone Tool Manufacture Strategies and Lithic Raw Material Exploitation in Coastal Patagonia, Argentina: A Multivariate Approach

Table 1

Absolute and relative frequencies of the different types of tools, lithic raw materials, and the fragmentation in the sample analyzed. The total 𝑛 of each sample is also shown. *The frequency of artifacts and raw materials differs because the unidentified artifacts have been eliminated of the table. DFGR: dark fine-grained rocks (sensu [29]). “Expedient core” signifies a core with four or less scars.
