Moiapu 3: Settlement on Moiapu Hill at the very end of Lapita, Caution Bay hinterland

The Caution Bay archaeological project on the south coast of mainland Papua New Guinea has excavated 122 sites over a 9 km2 area. Lapita ceramics appear at a number of sites at c. 2900 cal. BP. Here we present the results of excavations at Moiapu 3, a site that helps define the end of the dentate-stamped Lapita phase of this region. It is suggested that the decline and ultimate cessation of dentate stamping related to a loss of symbolism during a period of major socioeconomic readjustment and innovation.
