South American farming cultures found in the Lower and Middle Amazon areas of Amazonia and tentatively dated to c.ad 400–500. Characterized by their ceramic assemblages which belong to the Incised Rim Horizon Style of the Amazon Basin. Some of the settlements of this phase are extremely large: the midden at the type-site of Manacapurú, Brazil, is approximately 2km long by 400m wide.
