New ages for flowstone, sediments and fossil bones from the Dinaledi Chamber are presented. We combined optically stimulated luminescence dating of with U-Th palaeomagnetic analyses flowstones to establish that all containing Homo naledi fossils can be allocated a single stratigraphic entity (sub-unit 3b), interpreted deposited between 236 ka 414 ka. This result has been confirmed independently by three H. teeth U-series electron spin resonance (US-ESR) dating. Two scenarios were tested...
ABSTRACT The conversion of bedrock to regolith marks the inception critical zone processes, but factors that regulate it remain poorly understood. Although thickness and degree weathering are widely thought be important regulators development its water‐storage potential, functional relationships between properties processes generate documented. This is due in part fact difficult characterize by direct observations over broad scales needed for process‐based understanding zone. Here we use...
We present a concerted international effort to cross‐calibrate five synthetic Th isotope reference materials (UCSC “A”, OU “U”, WUN, IRMM‐35 and IRMM‐36), six rock TML, Icelandic ATHO, USGS BCR‐2, W‐2, BHVO‐2, LV18) using multi‐collector inductively coupled plasma‐mass spectrometry (MC‐ICP‐MS). then compare our new values with compilation of literature mass spectrometric data for these derive recommended “consensus” 230 Th/ 232 each. also dilution U concentration four W‐2).
Reversing the field Do terrestrial geomagnetic reversals have an effect on Earth's climate? Cooper et al. created a precisely dated radiocarbon record around time of Laschamps reversal about 41,000 years ago from rings New Zealand swamp kauri trees. This reveals substantial increase in carbon-14 content atmosphere culminating during period weakening magnetic strength preceding polarity switch. The authors modeled consequences this event and concluded that minimum caused changes atmospheric...
Abstract Explanations for the Upper Pleistocene extinction of megafauna from Sahul (Australia and New Guinea) remain unresolved. Extinction hypotheses have advanced climate or human-driven scenarios, in spite over three quarters lacking reliable biogeographic chronologic data. Here we present new north-eastern Australia that suffered sometime after 40,100 (±1700) years ago. Megafauna fossils preserved alongside leaves, seeds, pollen insects, indicate a sclerophyllous forest with heathy...
Abstract The timing of the first arrival Homo sapiens in East Asia from Africa and degree to which they interbred with or replaced local archaic populations is controversial. Previous discoveries Tam Pà Ling cave (Laos) identified H. Southeast by at least 46 kyr. We report on a recently discovered frontal bone (TPL 6) tibial fragment 7) found deepest layers TPL. Bayesian modeling luminescence dating sediments U-series combined U-series-ESR mammalian teeth reveals depositional sequence...
Abstract The largest ever primate and one of the southeast Asian megafauna, Gigantopithecus blacki 1 , persisted in China from about 2.0 million years until late middle Pleistocene when it became extinct 2–4 . Its demise is enigmatic considering that was few great apes to go last 2.6 years, whereas others, including orangutan, survived present 5 cause disappearance G. remains unresolved but could shed light on resilience fate megafauna this region 6 Here we applied three multidisciplinary...

Soils are key to ecosystems and human societies, their critical importance requires a better understanding of how they evolve through time. However, identifying the role natural climate change versus activity (e.g. agriculture) on soil evolution is difficult. Here we show that for most past 12,300 years erosion development were impacted differently by variability, as recorded sediments deposited in Lake Dojran (Macedonia/Greece): short-lived ( < 1,000 years) climatic shifts had no effect but...
