“…The bioavailable Sr in the Harbin and the nearby areas has the lowest 87 Sr/ 86 Sr ratios (<0.711) in China ( Figure S3 ), which is thought to be related to the mafic-ultramafic silicate rocks of the Xing'an-Mongolian orogenic belt. 18 These Sr isotopic data strongly suggest that they shared a common geological environment and bioavailable Sr source. The sediments adhered in the nasal cavity of the Harbin cranium consist of dark gray sandstone, most similar to those from the layer between 6.6 and 12.5 m of the DJ core.…”

Unsystematic recovery of the Harbin fossil cranium and a long history since the discovery impede its accurate dating -Geochemical analyses, including non-destructive X-ray fluorescence, rare earth elements, and the strontium isotopes, suggest that the fossil cranium was from a bed of lacustrine sediments aged between 138 and 309 thousand years ago in the Harbin region -Uranium-series disequilibrium dating directly on the cranium suggests that the cranium is older than 146 thousand years ll www.cell.com/the-innovation

“…These errors are low when compared with other spatial interpolation presented in literature for isoscapes (e.g. Willmes et al, 2018;Adams et al, 2019;Wang et al, 2020). Such low values are possibly related to the high number of samples considered in this study (total n = 1920), evenly distributed across Italy (see Figure 1), compared to the available literature studies.…”

We present a novel database of environmental and geological 87Sr/86Sr values (n = 1920) from Italy, using literature data and newly analysed samples, for provenance purposes. We collected both bioavailable and non-bioavailable (i.e. rocks and bulk soils) data to attain a broader view of the Sr isotope variability of the Italian peninsula. These data were used to build isotope variability maps, namely isoscapes, through Kriging interpolations. We employed two different Kriging models, namely Ordinary Kriging and Universal Kriging, with a geolithological map of Italy categorized in isotope classes as external predictor. Model performances were evaluated through a 10-fold cross validation, yielding accurate 87Sr/86Sr predictions with root mean squared errors (RMSE) ranging between 0.0020 and 0.0024, dependent on the Kriging model and the sample class. Overall, the produced maps highlight a heterogeneous distribution of the 87Sr/86Sr across Italy, with the highest radiogenic values (>0.71) mainly localized in three areas, namely the Alps (Northern Italy), the Tuscany/Latium (Central Italy) and Calabria/Sicily (Southern Italy) magmatic/metamorphic terrains. The rest of the peninsula is characterized by values ranging between 0.707 and 0.710, mostly linked to sedimentary geological units of mixed nature. Finally, we took advantage of the case study of Fratta Polesine, to underscore the importance of choosing appropriate samples when building the local isoscape and of exploring different end-members when interpreting the local Sr isotope variability in mobility and provenance studies. Our user-friendly maps and database are freely accessible through the Geonode platform and will be updated over time to offer a state-of-the-art reference in mobility and provenance studies across the Italian landscape.

“…In this study, we compiled 87 (Evans et al, 2010;Montgomery, 2010). However, distinguishing non-locals from locals and identifying their possible geographic place of origin are challenging and require an accurate baseline map showing the distribution of bioavailable 87 Sr/ 86 Sr across a wide region (Bataille et al, 2020;Wang and Tang, 2020). In practice, directly sampled environmental materials, such as soil leachates, surface and groundwater, plants, and animal skeletons, form the basis of bioavailable 87 Sr/ 86 Sr maps (Bentley and Knipper, 2005;Maurer et al, 2012;Ventresca Miller et al, 2017;Snoeck et al, 2020).…”

The Circulation of Ancient Animal Resources Across the Yellow River Basin: A Preliminary Bayesian Re-evaluation of Sr Isotope Data From the Early Neolithic to the Western Zhou Dynasty

Many questions still remain regarding the acquisition and circulation of ancient domesticated animals across the Yellow River Basin, one of the key areas for the development of complex societies in ancient China. Here, we re-evaluate previously published strontium isotope data (87Sr/86Sr, n = 167) from tooth enamel of domesticated animals at 10 archaeological sites in the Yellow River Basin to shed new light on the transition between the Neolithic (7000–5000 BCE) and the Western Zhou Dynasty (1046–771 BCE). The results show that from the Late Neolithic to the Western Zhou Dynasty, some domesticated animals, mostly cattle and sheep, were increasingly sourced from non-local areas. We employed Bayesian methods to define an isoscape of bioavailable Sr for the Yellow River Basin and to show the considerable diversity in the origins of non-local domesticated animals, some of which may have come from locations hundreds of kilometers away from the site as early as the Late Neolithic. The increasingly variable 87Sr/86Sr ratios of domesticated animals from the Neolithic to the Western Zhou Dynasty are consistent with that of associated human remains, and also match the archaeological and zooarchaeological evidence for increased circulation of animal products in the Yellow River Basin. Therefore, we infer that local economies increasingly incorporated non-local animals as part of wider circulation networks that emerged with the development of complex societies since the Late Neolithic.
