Two sites of the Neandertal-associated Middle Paleolithic Iberia, dated to as early approximately 50,000 years ago, yielded perforated and pigment-stained marine shells. At Cueva de los Aviones, three umbo-perforated valves Acanthocardia Glycymeris were found alongside lumps yellow red colorants, residues preserved inside a Spondylus shell consist lepidocrocite base mixed with ground, dark red-to-black fragments hematite pyrite. A Pecten shell, painted on its external, white side an orange...
It is commonly accepted that some of the latest dates for Neanderthal fossils and Mousterian industries are found south Ebro valley in Iberia at ca. 36 ka calBP (calibrated radiocarbon date ranges). In contrast, to north disappears shortly before Proto-Aurignacian appears 42 calBP. The latter most likely produced by anatomically modern humans. However, two-thirds from dates, a technique particularly sensitive carbon contaminants younger age can be difficult remove using routine pretreatment...
There is extensive debate concerning the cognitive and behavioral adaptation of Neanderthals, especially in period when earliest anatomically modern humans dispersed into Western Europe, around 35,000–40,000 B.P. The site Grotte du Renne (at Arcy-sur-Cure) great importance because it provides most persuasive evidence for complexity among Neanderthals. A range ornaments tools usually associated with human industries, such as Aurignacian, were excavated from three Châtelperronian levels at...
Elemental records in teeth reveal prehistoric seasons of Neanderthal birth, weaning, childhood illness, and neurotoxic exposures.
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...
The earliest claim for domesticated rice in Island Southeast Asia (4960–3565 cal BP) derives from a single grain embedded ceramic sherd Gua Sireh Cave, Borneo. In first assessment of spikelet-base assemblages within pottery sherds using quantitative microCT analysis, the authors found no additional remains this to support early date farming; analysis more recent (1990–830 BP), however, indicates that 70 per cent spikelet bases are rice. This technique offers high degree contextual and...
A recent study into prescreening techniques to identify bones suitable for radiocarbon dating from sites known poor or variable preservation (Brock et al. 2007, 2010a) found that the percent nitrogen (%N) content of whole bone powder was most reliable indicator collagen preservation. Measurement %N is rapid, requires little preparation material, and relatively cheap. The technique reduces risk needlessly sampling valuable archaeological objects, as well saving time money on their...
Torres et al . (2010 ) published a series of radiocarbon, AAR, ESR and OSL dates from the site El Sidrón, northern Spain, which is notable for discovery partial remains 12 Neanderthals. Whilst non‐radiocarbon methods suggested an age beyond 32 600–46 300 years, direct radiocarbon on human fossils were inconsistent, ranging between 10 000 50 bp This study uses ultrafiltration pre‐treatment protocol to obtain date 48 400 ± 3200 (OxA‐21 776) bone fragment confirm antiquity Neanderthal...
An extensive series of 44 radiocarbon (14C) and 37 optically stimulated luminescence (OSL) ages have been obtained from the site Riwi, south central Kimberley (NW Australia). As one earliest known Pleistocene sites in Australia, with archaeologically sterile sediment beneath deposits containing occupation, chronology is important renewed debates surrounding colonization Sahul. Charcoal preserved throughout sequence within multiple discrete hearth features. Prior to 14C dating, charcoal has...
This paper presents a reassessment of the archaeological record at Leang Burung 2, key early human occupation site in Late Pleistocene Southeast Asia. Excavated originally by Ian Glover 1975, this limestone rock-shelter Maros karsts Sulawesi, Indonesia, has long held significance our understanding dispersals into 'Wallacea', vast zone oceanic islands between continental Asia and Australia. We present new stratigraphic information dating evidence from 2 collected during course excavations...
Anesthetic agents are known greenhouse gases with hundreds to thousands of times the global warming impact compared carbon dioxide. We sought mitigate negative environmental and financial impacts our practice in perioperative setting through multidisciplinary staff engagement provider education on flow rate reduction volatile agent choice. These efforts led a 64% per case dioxide equivalent emissions (163 kg Fiscal Year 2012, 58 2015), as well cost savings estimate $25,000 month.
We examine the southern Vietnamese site of Rach Nui, dated to between 3390 and 3850 cal BP, in context three major aspects Neolithic Mainland Southeast Asia: mound formation chronology, construction techniques, subsistence economy. Results indicate that this ca. 75 m diameter, 5 high mound, comprising over a dozen phases earthen platforms, upon which were raised sophisticated wooden structures, was built <200 years. While consuming domesticated millet, rice, occasionally dogs pigs, main...
During the laboratory pretreatment of samples for radiocarbon dating, small amounts carbon may be added to a sample. Contamination can incorporated at any stage: during chemical pretreatment, combustion CO 2 , graphitization, or accelerator mass spectrometry (AMS) measurement. Such contamination is often modern in age, and so have an especially severe effect on older than ∼25 ka BP. extraction collagen from bone using ultrafiltration protocol Oxford Radiocarbon Accelerator Unit (ORAU), young...
