Sherds as archaeobotanical assemblages: Gua Sireh reconsidered

Abstract

The earliest claim for domesticated rice in Island Southeast Asia (4960-3565 cal BP) derives from a single grain embedded in a ceramic sherd from Gua Sireh Cave, Borneo. 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. Show more
