Archaeological Studies of the Middle and Late Holocene, Papua New Guinea. Part VI. Revised dating of Type X pottery, Morobe Province
Type X is a distinctive post-Lapita pottery on Huon Peninsula and its adjacent islands in Papua New Guinea, for which Lilley originally proposed a time span from about 1600 to 850/550 cal. bp. The paper reviews this chronology in the light of new dates and the original data, and proposes that the duration of Type X should be shortened to about 1000–500 cal. bp. This revised chronology possibly lengthens the post-Lapita aceramic period on Huon Peninsula, and has implications for the history of trading across Vitiaz Strait.
