Investigating relationships among strontium, barium, and seasonality in wild baboons
Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ 18 O) to contrast elemental changes with seasonal rainfall in wild baboons. We employ 16 teeth from 11 South …
Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees. Multielemental maps of the enamel and dentine of 12 teeth from five wild‐born chimpanzees vary considerably. It appears that spatiotemporal patterns…
A strontium isoscape of north-east Australia for human provenance and repatriation
It has been estimated that up to 25% of Indigenous human remains held in Australian institutions are unprovenanced. Geochemical tracers like strontium isotope ratios ( 87 Sr/ 86 Sr) have been used globally for over 40 years to discern human provenance and provide independent data to aid in repatriation efforts. To reliably apply this technology, landscape 87 Sr/ 86 Sr isotope ratio variability must be quantified. In Australia, only a few studies …
Timing, magnitude and effects of late Holocene sea level drawdown on island habitability, Aitutaki, Cook Islands
Geologist Bill Dickinson argued that prior to late Holocene sea level fall, in many Pacific island settings low‐lying islands were awash, shallow nearshore environments were restricted and human settlement was constrained or sometimes impossible. Stable coastlines and islets of modern configuration only developed after the “cross‐over date”, when declining high‐tide levels fell below mid‐Holocene low‐tide levels, a regionally variable process. We…
Renewed Geoarchaeological Investigations of Mwanganda's Village (Elephant Butchery Site), Karonga, Malawi
The site of Mwanganda's Village, located along a paleochannel in northern Malawi, is one of only a few sites that have characterized the Middle Stone Age (MSA) of Malawi for decades (Clark & Haynes, ; Clark et al., ; Kaufulu, ). The Malawi Earlier‐Middle Stone Age Project has re‐examined the site using new mapping and chronometric tools in order to reinterpret the site's significance within the context of current debates surrounding human origins…
Human‐caused stratigraphic mixing of a coastal Hawaiian midden during prehistory: Implications for interpreting cultural deposits
Archaeologists rely on the spatial and temporal distribution of artifacts and other site‐based materials to understand the stratigraphic integrity of the matrix in which remains are embedded. Although they are aware of taphonomic and site formation processes that can cause post‐depositional movement of objects, misinterpretation can occur. We used high‐precision 230 Th dating of branch corals found throughout cultural layers of a coastal Hawaiian…
Chemical Comparison of Rare Chinese White Pottery From Four Sites of the Erlitou State: Results and Archaeometrical Implications
White pottery is among the most significant finds from China's earliest state, Erlitou ( c . 1900–1500 bc ). Samples were primarily discovered in small numbers from elite tombs of a few sites, leading to the hypothesis that they were made at only a few locations and then circulated regionally as prestige items. To facilitate determining provenances, we compare the ICP–MS trace elements and TIMS Sr isotopes of whiteware with two soil samples from …
