摘要：The advances in archaeological research in the Argentine Chaco designed to identify pottery components
through the use of numerical techniques are presented. As a result, a similarity model linking the levels excavated with
grids is obtained. To test the technique, radiocarbon dates on samples of the resulting groupings were made, which
confirm the existence of two diachronic human occupations. This application case reinforces the validity of the analytical
procedure allowing to optimize the selection of samples for producing radiocarbon dates. It also considers the review
criterion of previous zooarchaeological information to prove the existence of eco-temporal variation in the availability
and structure of resources.
