“…From a wider regional perspective, the eventual discovery of equally early sites in continental Southeast Asia would come as no surprise given the presence of very early industries in Pakistan at the site of Riwat dated to around 2.5 Ma (Rendell and Dennell,1985;Dennell, 2009), in southern India at Attirampakkam, which is older than 1.5 Ma (Pappu et al, 2011), Southern China with Longgupo dated to over 2.0 Ma (Hou and Zhao, 2010;Boëda and Hou, 2011) and insular Southeast Asia with Pacitan in Java (Sémah et al 2000) and the Mata Menge site in Flores around 0.8 Ma (Sondaar et al, 1994;Van den Bergh et al, 1996;Morwood et al, 1998;Simanjuntak et al, 2010). This probability has already been hinted at by earlier discoveries in Myanmar (Movius, 1943), Cambodia (Saurin, 1966) and Thailand (Sarasin, 1933;Van Heekeren, 1947), further reinforced by more recent finds from Northern Thailand (Zeitoun et al 2012). 1) Undifferentiated Quaternary deposits; 2) Quaternary basalts; 3) Tertiary; 4) Undifferentiated pre-Tertiary deposits; 5) Hydrographic network; 6) Major cities; 7) Location of radiometric samples (Pope et al, 1986 (in white) and Sasada et al, 1987 (in black)); 8) other known archaeological sites.…”
