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

Table 5

Main statistical differences between sectors. It is possible to discriminate groups of sites according to some core types, the presence of denticulate, the average of lithic raw materials that were exploited and the fragmentation ratio. These last two variables are the main ones used in differentiating between both areas of the coast.

Northern coast	Western coast
(i) Higher artifact and core types diversity, lower proportion of polyhedral cores.	(i) Lower artifact diversity, higher proportion of polyhedral cores.
(ii) Predominant use of locally available rocks (DFGR).	(ii) Predominant use of locally available rocks (chalcedonies, jaspers, and opals).
(iii) Lower fragmentation ratio than in the western coast.	(iii) Higher fragmentation ratio than in the northern coast.
