In a first assessment of spikelet-base assemblages within pottery sherds using quantitative microCT analysis, the authors found no additional rice remains within this sherd to support the early date of rice farming; analysis of a more recent Gua Sireh sherd (1990-830 cal BP), however, indicates that 70 per cent of spikelet bases are from domesticated rice. This technique offers a high degree of contextual and temporal resolution for approaching organic-tempered ceramics as well-preserved archaeobotanical assemblages.This research is supported by the Australian Government Research Training Program (RTP) Scholarship and the Australian Research Council Future Fellowship (FT150100420).application/pdfen-AU© Antiquity Publications Ltd, 2020Island Southeast AsiaBorneoarchaeobotanyrice domesticationmicroCT202010.15184/aqy.2020.1662022-04-03
