Description: Raqefet Cave is located in southeast Mount Carmel, Israel. It contains a long archaeological sequence with two major occ upations: in the early Upper Paleolithic (Levantine Aurignacian culture, ca. 36,000–35,000 cal. BP) and the Late Epipaleolithic (Natufian culture, ca. 14,000–12,000 cal. BP). Abundant charred remains were found in the cave’s deposits consisting of various species. Drawing on Δ13C values of dated Amygdalus sp. (almond) charcoal specimens, we sought to reconstruct Late Pleistocene precipitation patterns from a high-resolution archaeological record. The results produced the longest, single-site, plant-based paleoclimatic sequence in the southern Levant, and they generally correspond to other paleoclimatic proxies generated for the region. They indicate that the plant taxa and reconstructed precipitation levels were all in the range of modern eastMediterranean climate but with some notable fluctuations. Specifically, we highlight the rainfall differences between the dryer Levantine Aurignacian and the wetter Natufian cultures. © 2021 Elsevier Ltd
