The calcium carbonate and its implications for the analysis of archaeological faunal samples. The Laguna El Doce case (General López department, Santa Fe province)
Often, under certain conditions, concretions of calcium carbonate (CaCO3 ) appear on the surface of bone specimens recovered from archaeological sites. In order to assess how the deposition of CaCO3 influences the identification of anthropogenic and natural variables, and to see how far this can inc...

| Sumario: | Often, under certain conditions, concretions of calcium carbonate (CaCO3 ) appear on the surface of bone specimens recovered from archaeological sites. In order to assess how the deposition of CaCO3 influences the identification of anthropogenic and natural variables, and to see how far this can increase –or not- the observations of these variables, this paper presents an analysis of the taphonomic effects on a faunal sample from the archaeological site Laguna El Doce after the removal of calcium carbonate. The most represented taxa in the assemblage and those which contained evidence of anthropic modifications were selected [pampas deer (Ozotoceros bezoarticus), rhea (Rhea americana), guanaco (Lama guanicoe) and Artiodactyla, total NISP= 1814]. The results obtained allow observing a significant increase in the frequency of natural (i.e. rodents and root etching) and anthropic taphonomic agents, as well as the presence of other variables of interest such as weathering, manganese deposits, among others. |
