“…Some of them are well known to researchers, such as Lang Kamnan (Shoocongdej 2000), Ban Kao (Pookajorn 1984), Sai Yok (Heekeren and Knuth 1967), Don Noi (Bronson and Natapintu 1988) and Ongbah (Sørensen 1988) in Western Thailand; Spirit Cave (Gorman 1970), Banyan Valley (Reynolds 1992), Tham Phaa Chan (Bannanurag 1988;White and Gorman 2004), Obluang (Santoni et al 1986), Huai Hin (Forestier et al 2013) and Tham Lod (Chitkament et al 2016;Shoocongdej 2006), Ban Tha Si (Zeitoun et al 2013) and Doi Pha Kan (Celiberti et al 2018) in Northern Thailand; Laang Spean (Forestier et al 2015;Mourer and Mourer 1970;Sophady et al 2016) in Cambodia; Houay Pano (Zeitoun et al 2019b) andTam Hang (Patole-Edoumba et al 2015) in North Laos; Nguom (Ha 1995b), Son Vi (Nguyen 1994a), Hang Cho (Yi et al 2008) and Xom Trai (Nguyen 1994c) in Northern Vietnam. However, at the moment, it is impossible to compare all these sites with the technological approach, since only several sites have been studied using a chaîne opératoire method, including Laang Spean (Forestier et al 2015(Forestier et al , 2017, Huai Hin (Forestier et al 2013), Tham Lod (Chitkament et al 2016), Doi Pha Kan (Celiberti et al 2018), Houay Pano (Zeitoun et al 2019b) and Tam Hang (Patole-Edoumba et al 2015), revealing different degrees of typotechnological information. Overall, three major chaînes opératoires on cobbles are well represented at Laang Spean (Forestier et al 2015(Forestier...…”
