Uranium series dates from Qesem Cave, Israel, and the end of the Lower Palaeolithic, 2003, Barkai, R. , Gopher, A. , Lauritzen, S. E. , And Frumkin, A.
Israel is part of a geographical ?out of Africa? corridor for human dispersals. An important event in these dispersals was the possible arrival of anatomically modern humans in the Levant during the late Middle Pleistocene1,2,3. In the Levant the Lower Paleolithic ends with the Acheulo-Yabrudian complex, characterized by striking technological developments4,5 including the introduction of advanced technological innovations such as systematic blade production and the disappearance of hand-axes . These reflect new human perceptions and capabilities in lithic technology and tool function, as well as innovative human adaptation6. Qesem Cave, discovered in 2000, has a rich, well-preserved Acheulo-Yabrudian sequence holding great promise for providing new insights into the period. Here we report the dates of this cave obtained by U-series of speleothems and their implications. The results shed light on the temporal range of the Acheulo-Yabrudian and the end of the Lower Paleolithic, suggesting a long and unique cultural phase between the Lower Paleolithic Acheulian and the Middle Paleolithic Mousterian, starting well before 350 kyr and ending at ca. 200 kyr.

Evidence for habitual use of fire at the end of the Lower Paleolithic: Site formation processes at Qesem Cave, Israel, 2007, Karkanas, P. , Shahackgross, R. , Ayalon, A. , Barmatthews, M. , Barkai, R. , Frumkin, A. , Gopher, A. , And Stiner, M. C.
The Amudian (late Lower Paleolithic) site of Qesem Cave in Israel represents one of the earliest examples of habitual use of fire by middle Pleistocene hominids. The Paleolithic layers in this cave were studied using a suite of mineralogical and chemical techniques and a contextual sedimentological analysis (i.e., micromorphology). We show that the lower ca. 3 m of the stratigraphic sequence are dominated by clastic sediments deposited within a closed karstic environment. The deposits were formed by small scale, concentrated mud slurries (infiltrated terra rosa soil) and debris flows. A few intervening lenses of mostly in situ burnt remains were also identified. The main part of the upper ca. 4.5 m consists of anthropogenic sediment with only moderate amounts of clastic geogenic inputs. The deposits are strongly cemented with calcite that precipitated from dripping water. The anthropogenic component is characterized by completely combusted, mostly reworked wood ash with only rare remnants of charred material. Micromorphological and isotopic evidence indicates recrystallization of the wood ash. Large quantities of burnt bone, defined by a combination of microscopic and macroscopic criteria, and moderately heated soil lumps are closely associated with the woodash remains. The frequent presence of microscopic calcified rootlets indicates that the upper sequence formed in the vicinity of the former cave entrance. Burnt remains in the sediments are associated with systematic blade production and faunas that are dominated by the remains of fallow deer. Use-wear damage on blades and blade tools in conjunction with numerous cut marks on bones indicate an emphasis on butchering and prey-defleshing activities in the vicinity of fireplaces.
