SILVEIRA, Mario; LOPEZ, Lisandro  and  PASTORINO, Guido. Mobility, Exchange Networks And Circulation Of Goods In Southwestern Neuquén, Northern Patagonia, Argentina: The Marine Mollusks From Traful Lake. Intersecciones antropol. [online]. 2010, vol.11, n.2, pp.227-236. ISSN 1850-373X.

In this article the origin of fragments of marine shells found at Los Cipreses and Lariviere rock-shelters is presented. Consistent with studies by other authors in nearby areas in greater proximity to the Pacific coast, it was assumed that these fragments indicated contact with groups from the western side of the Chilean Andes. The results show that the shells correspond to marine or unknown fluvial fossils; a few pieces correspond to a marine gasteropod of great size, Adelomelon brasiliana, from the Atlantic Ocean and the bivalve Choromytilus chorus, probably from the Pacific. These data, and the recent analysis of samples of obsidian from sources located in southwestern Neuquén, which circulated far toward the Atlantic coast, highlight the complexity and extent of human mobility and interregional exchange networks.

Keywords : Marine mollusks; gastropoda; Adelomelon brasiliana; Obsidian artifacts; Neuquén; Argentinean Patagonia.
