An archaeological team has been excavating three ancient village sites-Barras, Agna, and Cussaia-looking in particular at kitchen waste dumps as a way to understand the villages' dietary patterns and trading relationships. What follows are brief summaries of their findings.

By excavating the kitchen area the archaeological team understands the ways of the ancient villages' consumption of food and the trading of the consumable items along with the potteries which can be found in the waste dump areas. By excavating these villages the pattern of growing crops can be understood if they cultivated or consumed wild crops, along with whether the society was agrarian or hunter-gathering. The dietary patterns of eating, drinking, and utensils with food residues can be examined.
