We excavated Khao Toh Chong rockshelter in Krabi and recorded archaeological deposits spanning the last 13,000 years. A suite of geoarchaeological methods suggest largely uninterrupted deposition, against a backdrop of geological data that show major changes in sea levels. Although there is a small assemblage of mostly undiagnostic ceramics and stone artefacts, there are some distinct changes in stone artefact technology and ceramic fabric. There is a substantial faunal assemblage, with changes in both the mammalian and shellfish taxa during the Pleistocene-Holocene transition that correlate with local sea level fluctuation. This assemblage provides an opportunity to explore subsistence behaviours leading up to the transition to the Neolithic. We explore the implications for current debates on the prehistoric origins of agricultural subsistence in mainland Southeast Asia. The data highlight the importance of local contingencies in understanding the mechanisms of change from foragers to agriculturalists.
