“…Currently, the earliest Hoabinhian deposits is considered to be the Xiaodong Rock shelter in Southwest China, dating back to about 43,000 BP (Ji et al, 2016).Similarly, the site of Huai Hin in Northwest Thailand, dated to approximately 3700 BP, is considered the last occurrence with a lithic production associated with ceramic sherds (Forestier et al, 2013;Zeitoun et al, 2008). Over a hundred Hoabinhian sites have been reported in Southeast Asia (Chung, 2008;Forestier et al, 2017;Moser, 2001;White, 2011;Zeitoun et al, 2008), raising questions about the variability of Hoabinhian lithic assemblages, including unexpected operational sequences on pebble matrix (Forestier et al, 2023(Forestier et al, , 2022. Nonetheless, despite these findings, the Hoabinhian people remain poorly understood from both cultural and material perspectives.…”
