A new sequence containing human remains from a previously unstudied cave, Bondi Cave, has been discovered in Georgia, with deposits dating to the Caucasian Upper Pleistocene. This site lies in the basin of Rioni-Kvirila Rivers, in the Imereti region of north-western Georgia. The site has yielded a long sequence with human occupations dated from~39 ka14C (uncalibrated) and thus covers the time span of the Middle Palaeolithic (MP)-Upper Palaeolithic (UP) transition in the region. Changes in the techno- logical features between the lower and upper part of the sequence indicate that Bondi Cave could potentially highlight the tempo and mode of the population replacement. Indeed, recent studies in the southern Caucasus (notably at Ortvale Klde, Western Georgia) suggest a very rapid occupation by modern humans replacing existing Neanderthal populations (Adler, 2002; Meshveliani et al., 2004; Bar-Yosef et al., 2006; Adler et al., 2008). The rich UP levels at the upper and middle parts of the new sequence offer data on modern human subsistence and technological behaviors, and on the humans who occupied this cave, as a human tooth has also been discovered in this part of the sequence.
