Kvemo Orozmani, Georgia: a new Lower Paleolithic archaeological site in the Southern Caucasus

The Southern Caucasus represent one of the hubs for the earliest range expansions of hominins during the Early Pleistocene, as evidenced by the extensive archaeological site at Dmanisi, Georgia. Here, we present findings from a new Lower Paleolithic archaeological site in Georgia: Kvemo Orozmani, which is located approximately twenty kilometers west of Dmanisi. Previous dating and analyses of phytoliths and sedimentology correlated the Kvemo Orozmani and nearby Zemo Orozmani sequences to the Dmanisi stratigraphy, indicating roughly contemporaneous localities (Messager et al., 2011). A recent revisit to the Kvemo Orozmani profile revealed Oldowan-like stone artifacts along with faunal remains. Subsequent excavations began in 2020 and have produced more lithic artifacts, faunal remains from numerous carnivores and ungulates, and a hominin tooth. The latter find doubles the number of hominin-bearing Early Pleistocene localities in the Southern Caucasus and offers potential insights into the hominin populations who expanded into this region. Here, we present our initial findings on site formation, archaeology, taphonomy, and paleontology and how this site fits into the greater context of the earliest hominin expansions into Eurasia.
