“…According to Andrews (1990), these categories are based both on the degree of modification by digestive corrosion and frequencies of affected elements. On the other hand, taphonomic evidences of human activities were evaluated, such as cut marks, pounding, scraping, intentional fracture, percussion marks and thermoalteration (e.g., Binford, 1981;Shipman et al, 1984;Blumenschine et al, 1996;Mengoni Goñalons, 1999;Pardiñas, 1999b;Medina et al, 2012). Based on color and texture of the bone surfaces and the uniformity of the attributes, the characterization of the type of thermoalteration such as burned, carbonized and calcined, was assessed (Shipman et al, 1984;Stiner et al, 1995).…”
