Resumo

this article we present the results of a series of analysis performed on a lithic artifact from the Itaparica industry, a limace, found in Lapa Grande de Taquaracu, an archaeological site bordering the Lagoa Santa area in Central Brazil. The site was occupied between 11.477 +/- 133 cal. BP and 1.087 +/- 78 cal. BP, and the archaeological record for this occupation is related to the archaeological Lagoa Santa Tradition. However, the artifact was found in deeper and relative older archaeological levels, in a different stratigraphy context. The technological analysis confirms its exotic nature, not corresponding to the Lagoa Santa industry, but to another Paleoindian archaeological tradition instead. Its technological features are similar to the limaces related to Itaparica Tradition lithic industries. It's important to notice that this is the only limace found at Lagoa Santa until now, and archaeological context did not allow us to associate it to the Lagoa Santa Tradition. In order to have an insight on the use of this artifact we performed some technological and micro-remain analysis. Various starch grains and other materials were recovered from the active parts of the artifact. The microbotanical analysis indicated the use of the artifact for processing starchy plants. As far as we know, this is the most ancient evidence of the processing of starchy plants in the Americas. (AU)
