Indirect dating of secondary cave burials in the Massim region of Papua New Guinea reveals last millennium reorganisation of social practices

Abstract

ABSTRACTIn the Massim Island region of southeastern Papua New Guinea secondary interment of skeletal remains was widely practiced historically, but its social context and regional expression in the deeper past remains uncertain. In this paper the chronology of secondary burial on Panaeati Island is established indirectly by reconstructing the cultural and spatiotemporal association of 21 clay pots placed with human skeletal remains at Biniwaga Cave, coincidently establishing the first whole vessel typology of Southern Massim Combed Pottery (SMCP) and Southern Massim Pottery (SMP). Comparison with excavated pottery assemblages on Panaeati and elsewhere in the region demonstrates that the Biniwaga pots are consistent with SMCP and early SMP, dating from 740 to 470 calBP. Secondary burial practices on Panaeati are contemporary with those recorded elsewhere in the region and coincide with changes in pottery production centres. Compared to excavated pottery assemblages from contemporary sites, a relatively narrow range of pots are represented at Biniwaga. It is hypothesised that pots were selected to reflect the cultural affiliation of deceased individuals during a period of increasing inter‐island interaction.
