Uranium Series Dating

Abstract Although radiocarbon (14C) dating, uranium-series dating, and optically stimulated luminescence (OSL) dating have been conducted for Upper Palaeolithic sites in the Nihewan Basin, northern China, there is room for constructing a detailed chronological framework. In this study, loess sediments collected from two Upper Palaeolithic sites, Youfang site and Hutouliang site, were dated using the single-aliquot regenerative-dose (SAR) OSL protocol. OSL measurements for palaeodoses estimation used fine-grained quartz samples extracted from loess. OSL dating results were obtained as 10–17 ka. These OSL ages were consistent with the related stratigraphy of Palaeolithic sites, archaeological evidence and independent 14C ages.

AbstractThe timing of the Neanderthal-associated Middle Palaeolithic demise and a possible overlap with anatomically modern humans (AMH) in some regions of Eurasia continues to be debated. The Iberian Peninsula is considered a possible refuge zone for the last Neanderthals, but the chronology of the later Middle Palaeolithic record has undergone revision and has increased the debate on the timing of Neanderthal extinction. Here we report on a study of the 5-m-thick archaeological stratigraphy of the Cardina-Salto do Boi, an open-air site located in inland Iberia, from which optically stimulated luminescence (OSL) ages were obtained for Middle and Upper Palaeolithic occupations preserved in overbank alluvial deposits. Geomorphology, archaeostratigraphy, stone-tool evolution, and OSL dating support the persistence of Neanderthals after 41 ka in central Iberia; the transition between the Middle Palaeolithic material culture and the AMH-associated Aurignacian blade and bladelet production is estimated to lie between 34.0 ± 2.0 ka and 38.4 ± 1.9 ka. Our results demonstrate that investigations focusing on different geomorphological situations are necessary to overcome the current limitations of the evidence and to establish more consistent models for Neanderthal disappearance and AMH expansion in the Iberian Peninsula.

Palaeolithic Art

Upper Palaeolithic art is found across much of Europe as portable (mobiliary) art, pictographs or engravings in deep caves, or as engravings in open-air sites. European Upper Palaeolithic art was among the first prehistoric art to be discovered by researchers, and it remains among the oldest dated art in the world. Since the late 1800s, a range of theoretical approaches have been used to comprehend its meaning(s), with most effort aimed at the construction of chrono-stylistic frameworks by which to understand the art’s origins and evolution over time. More recently, new analytical techniques such as radiocarbon and uranium-series dating, digital imaging, and 3-D recording have improved our abilities to analyse the art. The Iberian Peninsula is especially rich in post-Palaeolithic assemblages of varied ages, including some that progress into the Neolithic. In this context, current discussions are focused on continuities of deeply rooted Palaeolithic traditions into the Mesolithic and on ruptures at the onset of the Neolithic.

Uranium Series Dating

The radiometric dating of calcrete is often problematical because impurities and open system conditions affect the apparent ages obtained. By applying both radiocarbon and uranium-series dating to calcrete in colluvium, it is shown that such conditions can be identified. In correlation with the stratigraphy, it is found that partial recrystallization severely decreases the radiocarbon ages of the upslope and shallower samples further down, whereas incorporation of limestone fragments from bedrock significantly increases the apparent ages of some of the uranium-series samples. It is concluded that the hillslope calcrete at the study site near Sede Beker in the Negev Desert, Israel, mainly developed shortly after 40 kyr ago, at a time when the Jordan Valley was being inundated to form the fossil Lake Lisan. Since their formation would have required higher rainfall than today, the results provide further evidence that the whole region was experiencing an increase in precipitation.

Cave Art

Indonesia harbors some of the oldest known surviving cave art. Previously, the earliest dated rock art from this region was a figurative painting of a Sulawesi warty pig (Sus celebensis). This image from Leang Bulu’ Sipong 4 in the limestone karsts of Maros-Pangkep, South Sulawesi, was created at least 43,900 years ago (43.9 ka) based on Uranium-series dating. Here, we report the Uranium-series dating of two figurative cave paintings of Sulawesi warty pigs recently discovered in the same karst area. The oldest, with a minimum age of 45.5 ka, is from Leang Tedongnge. The second image, from Leang Balangajia 1, dates to at least 32 ka. To our knowledge, the animal painting from Leang Tedongnge is the earliest known representational work of art in the world. There is no reason to suppose, however, that this early rock art is a unique example in Island Southeast Asia or the wider region.
