The Quaternary landscapes, chronostratigraphy, and paleoenvironments of the Chalbi Desert, Kenya
The Chalbi Desert, located in eastern Africa, is a significant but overlooked archive of the Pleistocene and Holocene periods that could add insight into investigations on human evolution. We revisited southeastern Chalbi Desert landforms between the towns of Kargi and Maikona to improve the chronostratigraphy and provide paleoenvironmental context. Direct U-series and electron spin resonance dating of various fossil teeth recovered from a deflat…
Seasonality and water source strategies in the Neolithic Near East (ca. 8,000–5,000 BCE)
Previous studies have demonstrated that enamel oxygen isotope values (δ 18 O) reflect rainfall variability experienced by wild primates and ancient humans, providing insights into local climatic conditions. However, it remains less clear whether seasonal patterns can be consistently detected in premodern human communities experiencing different local water dynamics, or how these patterns may vary regionally. Here we present 1958 ion microprobe δ …
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…
New paleohydroclimate record of the MIS 5e/5d transition from Yelini Cave, central Anatolian region of Türkiye
This study presents the results of a detailed paleoclimate investigation on stalagmite YL-1 (Yelini Cave, Türkiye). YL-1 grew between 117.13 (+0.57/−0.44) ka and 114.87 (+1.63/−2.89) ka within Greenland Stadial 26, indicating a positive moisture balance during the stadial conditions in this semi-arid region. Rainfall is significantly affected by sub-cloud and surface evaporation and decreasing net effective winter precipitation is recorded by hig…

Oldest cave art found in Sulawesi
An image of a pig painted at least 45,500 years ago on a cave wall in Sulawesi may be the earliest figurative rock art ever found.
Recent environmental changes in the Yunnan–Guizhou Plateau inferred from organic geochemical records from the sediments of Fuxian Lake
During the past century, many lacustrine environments have changed substantially at the ecosystem level as a result of anthropogenic activities. In this study, the distributions of n-alkane homologues, carbon isotopes (δ13Corg), organic carbon, and the C/N atomic ratio in two sediment cores from Fuxian Lake (Yunnan, southwest China) are used to elucidate the anthropogenic impacts on this deep, oligotrophic, freshwater lake. The carbon preference …
New ages of the world's largest-ever marsupial
Isotopic analyses of prehistoric human remains from the Flinders Group, Queensland, Australia, support an association between burial practices and status
The place beyond the trees
Olieboomspoort is one of the few rock shelters in the vast interior of southern Africa documenting pulses of occupation from the Acheulean until the end of the Later Stone Age. Revil Mason excavated the site in 1954 and attributed the large Middle Stone Age (MSA) lithic assemblage to his middle phase of the so-called Pietersburg Industry. Recent work at the site has focused on the Holocene layers, but little is known about the earlier phases of s…

Historical droughts in Southeast Australia recorded in a New South Wales stalagmite
The Murray Darling Basin contains 40% of Australia’s farms and is subject to multi-year droughts that put severe pressure on southeast Australia’s freshwater resources. Yet the long-term frequency, timing and potential severity of these droughts is unknown, as there are few high-resolution paleoclimate records from the basin that extend past the instrumental era. In this study, we investigate the potential of stalagmites from Careys Cave, Wee Jas…

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 …

Additional evidence for early modern human morphological diversity in Southeast Asia at Tam Pa Ling, Laos
Early Modern Humans from Tam Pà Ling, Laos
Despite the importance of its geographical position for early modern human migration through Australasia, the Indochinese Peninsula has produced relatively few fossils or well-documented archaeological sites, resulting in a poor chronology for early occupation. Tam Pà Ling (TPL), a cave in northern Laos, is one of the rare sites yielding fossils contemporaneous with the earliest migrants into Australasia within a securely established chronology. …

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…

Th dates for dedicatory corals from a remote alpine desert adze quarry on Mauna Kea, Hawai'i
The authors show how sites in upland Hawai'i may be dated using uranium series radiogenic measurements on coral. The sites lie in a quarry, inland and at high altitude, with little carboniferous material around, and radiocarbon dating is anyway problematic here for the first millennium. Freshly broken coral had been transported to these sites, remote from the sea - no doubt for ritual purposes. Giving a date in the fifteenth century with an error…

U-Series dating of locality 15 at Zhoukoudian, China, and implications for hominid evolution
This paper reports U-series dates on speleothem samples from Locality 15 at Zhoukoudian, one of the richest Paleolithic sites in northern China. The age of the lower part of Layer 2 is securely bracketed between 155,000 and 284,000 yr. The underlying Layer 3 dates back at least 284,000 yr. Layer 4, further below, should be older still, possibly by a cycle on the SPECMAP time scale before 284,000 yr ago. These ages, much greater than the previous …
Speleothem master chronologies
The stable isotope records of four stalagmites dated by 19 TIMS uranium series ages are combined to produce master chronologies for δ 18 O and δ 13 C. The δ 18 O records display good overall coherence, but considerable variation in detail. Variability in the δ 13 C records is greater, but general trends can still be dis cerned. This implies that too fine an interpretation of the structure of individual isotopic records can be unreliable. Speleoth…

High-resolution and Precisely dated record of weathering and hydrological dynamics recorded by manganese and rare-earth elements in a stalagmite from Central China
Manganese (Mn) and rare-earth elements (REEs) in a stalagmite (SJ3) collected from Central China were analyzed, using an ICP-MS method for the precise determination of > 40 trace elements in geological samples by enriched-isotope internal standardization. Unlike speleothem Mn and REEs investigated by cathodoluminescence, which may be incorporated into crystal lattice, the Mn and REEs analyzed in SJ3 should come largely from colloidal and particle…
Decoupling of stalagmite-derived Asian summer monsoon records from North Atlantic temperature change during marine oxygen isotope stage 5d
The Asian monsoon is an important component of the global climate system. Seasonal variations in wind, rainfall, and temperature associated with the Asian monsoon systems affect a vast expanse of tropical and subtropical Asia. Speleothem-derived summer monsoon variation in East Asia was previously found to be closely associated with millennial-scale change in temperature in the North Atlantic region between 75 and 10 ka. New evidence recovered fr…
Distinct climate change synchronous with Heinrich event one, recorded by stable oxygen and carbon isotopic compositions in stalagmites from China
Uranium-series dating of oxygen and carbon isotope records for stalagmite SJ3 collected in Songjia Cave, central China, shows significant variation in past climate and environment during the period 20–10 ka. Stalagmite SJ3 is located more than 1000 km inland of the coastal Hulu Cave in East China and more than 700 km north of the Dongge Cave in Southwest China and despite minor differences, displays a clear first-order similarity with the Hulu an…

Microatoll record for large century-scale sea-level fluctuations in the mid-Holocene
Coral microatolls have been long used as precise indicators of past sea level, but their use for precise definition of detailed sea-level fluctuations is still rare. Here we report twelve high-precision thermal ionization mass spectrometric 230 Th ages for twelve rims of five mid-Holocene microatolls from an emerged reef terrace at Leizhou Peninsula, northern South China Sea. This is a tectonically stable area, enabling us to reconstruct both the…

Paleoprecipitation record from coral Sr/Ca and δ18O during the mid Holocene in the northern South China Sea
Coupled high-resolution Sr/Ca and δ 18 O records of a modern and a mid-Holocene coral from Sanya in the southern Hainan Island, northern South China Sea (SCS), were reported and the residual δ 18 O (Δδ 18 O) were calculated to indicate precipitation change in this region. Unlike other paleoclimate studies, this study focused on changes of precipitation time rather than precipitation amount. As negative Δδ 18 O peaks in coral generally correspond …
U-series dates of Great Barrier Reef corals suggest at least +0.7 m sea level ~7000 years ago
Strong evidence from field observation and high-precision TIMS U-series dating of exposed in situ massive corals and exposed microatolls on Magnetic Island, Great Barrier Reef, indicates that the relative sea level was at least 0.7 m higher than present ~7000 calendar years (cal yr) ago, and culminated to at least ~1.6 m higher than present ~5800 cal yr ago. The present sea level was probably first reached around 7300—7100 cal yr ago. Together wi…

Human‐caused stratigraphic mixing of a coastal Hawaiian midden during prehistory
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
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 …
