“…There are many documented assemblages of osseous industry throughout Thailand, and northern Vietnam, as well as early Holocene projectiles and hafted points with evidence of fibres and resins throughout the broader region (Barton et al, 2009;Harrisson/Medway, 1962;Higham, 1993;Pawlik, 2013;Rabett, 2008Rabett, , 2012Rabett, & 2016Rabett/Piper, 2012;Zhang et al, 2015). In southern Vietnam, ancient bone technology is discussed from two excavated mounds located approximately 10km from each other on the banks of the Vàm Co Tây River near the Cambodian border (Bùi et al 2006;Ngô/Bùi, 1997;Hull, 2018). As we are searching for possible signs of mobility within the region in the use of projectile technology including reasons for technical change in this material domain (David et al, this volume;Yu, 2006), this paper will focus on presenting the characteristic bone points from these two Vietnamese mounds; Gò Ô Chùa and Lò Gạch (Fig.…”
