Prei Khmeng, a village 13 km northwest of Siem Reap, Cambodia, is noted for the presence of one of the region's earliest monuments, Prasat Prei Khmeng. Aside from its ruined temple, Prei Khmeng is an important prehistoric occupation site that immediately pre-dates the foundation of the temple. First excavated by a Franco-Cambodian team in the early 2000s, the site was revisited in 2014 by an Australian-Cambodian research team. Recent research revealed Iron Age domestic occupation as well as inhumation burials. The burial assemblage provides evidence of regional trade and exchange and mortuary wealth differentiation. Bioarchaeological examination of the individuals interred at the site reveals intentional dental modification and perimortem blunt and sharp force skeletal trauma. This research sheds light on this important epoch in prehistory, a juncture between the prehistoric and protohistoric period in Cambodia, which was a time of substantial socio-political transformation.
