This is the thirty‐sixth list of AMS radiocarbon determinations measured at the Oxford Radiocarbon Accelerator Unit (ORAU). Amongst some of the sites included here are the latest series of determinations from the key sites of El Mirón (Spain) and Sutton Courtney (UK), as well as others dating to the Palaeolithic, Mesolithic and later periods. Submitters of the material provide comments on the significance of the results. [ABSTRACT FROM AUTHOR]

This is the 35th list of AMS radiocarbon determinations measured at the Oxford Radiocarbon Accelerator Unit ( ORAU). Amongst some of the sites included here are the latest series of determinations from the key sites of Abydos, El Mirón, Ban Chiang, Grotte de Pigeons ( Taforalt), Alepotrypa and Oberkassel, as well as others dating to the Palaeolithic, Mesolithic and later periods. Comments on the significance of the results are provided by the submitters of the material. [ABSTRACT FROM AUTHOR]

Torres et al. (2010) published a series of radiocarbon, AAR, ESR and OSL dates from the site of El Sidrón, northern Spain, which is notable for the discovery of the partial remains of 12 Neanderthals. Whilst the non-radiocarbon methods suggested an age beyond 32 600-46 300 years, direct radiocarbon dates on the human fossils were inconsistent, ranging between 10 000 and 50 000 bp. This study uses the ultrafiltration pre-treatment protocol to obtain a date of 48 400 ± 3200 bp (OxA-21 776) on a bone fragment and confirm the antiquity of the Neanderthal assemblage. Moreover, it demonstrates the comparability of the ultrafiltration and ninhydrin bone radiocarbon pre-treatment protocols, and highlights the need for appropriate screening methods where valuable collections with poor biomolecular preservation are sampled for collagen extraction.

The article presents the thirty-third list of dates measured at the Oxford Radiocarbon Accelerator Unit (ORAU) by Oxford University in Oxford, England. It states that such dates include those measured in laboratories funded by the Natural Environment Research Council (NERC), Arts and Humanities Research Council (AHRC), and English Heritage. Comments on the dates of archaeological and environmental samples are also provided.
