South American farming communities found in the Marajo area of Amazonia and tentatively dated to c.ad 1000–1400. Characterized by their ceramic assemblages which belong to the Polychrome Horizon Style of the Amazon Basin. Tangas, pottery pubic covers, have been found together with labrets, clay stools, spindle whorls, and figurines of seated humans. Burial mounds were built, and often contain secondary burials in anthropomorphic polychrome urns. Marajoara settlements comprise large artificially constructed earthen mounds, often 50 m by 35 m by 6 m high. Multi‐family houses were built on these mounds which raised the houses well above any seasonal floodwaters.
