Discovery of a Mesolithic burial near the painted rock-shelter of Ban Tha Si (Lampang province, Northern Thailand): Implications for regional mortuary practices

Although the oldest Neolithic cultures in eastern Asia have for the most part been documented in China and Vietnam, a large number of Early Metal Age sites have been reported in northeastern Thailand. On the other hand, the Hoabinhian, principally identified by its characteristic unifacial tools, is known throughout the Late Pleistocene up until 3000 BP and is spread across the whole of continental Southeast Asia. The chronology of Hoabihnian lithic assemblages is still poorly documented and burials from the period are scarce and often do not provide enough information to allow the evolution of regional mortuary practices to be investigated. Here we describe a burial dated to 7047 ± 53 BP found associated with a Hoabinhian stone tool assemblage and fauna near the painted rock-shelter of Ban Tha Si. This discovery provides important new chrono-cultural information for continental Southeast Asia, especially with regard to changing regional mortuary practices.
