Cultural groupings found in the Rio Ucayali area of Amazonia in the period c.ad 1200–1500, characterized by its varied ceramic assemblages which belong to the Polychrome Horizon in the Amazon Basin. Vessels include square‐shaped open dishes, anthropomorphic urns, and pots with a square‐shaped cross‐section. The wares are well made and usually decorated with painted designs. Ethnohistorical records suggest that the Rio Ucayali region was colonized by Cocama and Omagua tribes from the middle Amazon, the result of which is probably the Caimito Complex. The polychrome ceramic traditions continued until recent times among the Shipibo and Cashibo groups.
