Tequinho Geoglyph Site and Early Polychrome Horizon 300 BC - AD 300/500 in the Brazilian State of Acre

In Amazonian archaeological discussion the concept of tradition presupposes a keen connection between pottery styles and specific language groups. Multicultural traditions or transcultural adaptions are often pushed aside. Denise Schaan returned to the concept of horizon in order to explain a number of archaeological phenomena from a wide geographical and chronological perspective. Also in this study the concept of Polychrome Horizon is used, but it is divided between Early and Late Polychrome Horizons. At the same time an entirely new area, eastern Acre, and its archaeological sub-tradition Tequinho, dated 50BC –AD200 with its polychrome pottery, are brought into the discussion. Tequinho is situated in the interfluvial terra firme environment, and by its geographic position mediated contacts between the headwaters of the Amazon, the Ucayali and the Madeira rivers.Peer reviewe
