Techno-Morphological and Use-Wear Analysis on Lithic and Bone Tools from Campo Laborde Site (Pampean Region, Argentina)

Abstract

Investigations carried out at Campo Laborde site provide new evidence for technological strategies associated with hunting and butchering a giant ground sloth (Megatherium americanum) during the early Holocene (Messineo and Politis 2009; Politis and Messineo 2008). Debitage analysis developed previously indicates that the last stages of the lithic reduction sequences (production and resharpening of cutting tools) were recognized both on nonlocal quartzite and on local raw materials such as chert and silicified dolomite (Messineo 2008; Politis and Messineo 2008). This paper reports technomorphological and use-wear analysis performed on two lithic and two megamammal bone tools found in the site.
