While carbon dating has yet to be done on El Pozito, Coppa believes it to be around 2,000 years old (Late Archaic Age), based on the objects he's found so far, but he's hoping the settlement is much older than that. Particularly because what he's really looking to find is a necropolis – with burials spanning centuries – in order to glean genetic insights. And there's a good chance he will, because no site where humans lived has not been associated with a necropolis.
