Accelerator mass spectrometry (AMS) allows radiocarbon dating to be carried out by direct counting of14C atoms, rather than the conventional counting of radioactive disintegrations. The result is that samples up to 1000 times smaller can be handled. The approach was tested in principle by 1977 and for archaeological operation by 1983. More than 2000 samples per year are now being dated worldwide. The machines can now operate to about ± 80 years or better. Dates older than 40,000 years have not… Expand
Bone need not remain an elephant in the room for radiocarbon dating
Solid evidence supports that only molecular-level dating accommodates all known bone contaminants and guarantees complete removal of humic and fulvic acids and conservation substances, and innovation and more funded research is required to develop affordable analytical chemistry that can handle low-mass samples of collagen amino acids.

Using a Silica Substrate to Monitor the Effectiveness of Radiocarbon Pretreatment
The objective of radiocarbon pretreatment is to eliminate any contaminant carbon from the sample material. Solvent washes and acid-base-acid (ABA) procedures are widely used for this purpose.Expand
The advantages of AMS to field archaeologists
Abstract AMS has successfully resolved several controversies concerning the anomalously early appearance of early objects (domesticated plants in both the Old and New Worlds, Late Pleistocene peopleExpand
14C data and the early colonization of Northwest South America
The aim of this paper is to make a critical appraisal of the available 14 C dataset from Northwest South America (Colombia) corresponding to the Pleistocene/Holocene transition (ca. 12,000e8000 14 CExpand
The Impact of Radiocarbon Dating on Near Eastern Prehistory
As within other scientific inquiries, archaeology embraces a strong interplay between technology and theory. Of the many technological advances in modern archaeology, 14C dating has had perhaps theExpand
The origins of agriculture in the Americas
Three independent centers of domestication and agricultural origin have been identified in the Americas: the south‐central Andes, Mexico, and most recently, eastern North America; in each of the three regions, the earliest domesticates were believed to date between 7,000 and 10,000 B.P. Expand
Makers of the early Aurignacian of Europe.
The overall picture is one of an extended period of cultural contact, involving some degree of genetic exchange, between Neandertals and early modern Europeans, and perhaps for 8,000-10,000 years or longer. Expand
Mid-Holocene evidence of Cucurbita sp. from central Maine
Current evidence suggests that the first two hypotheses are unlikely, but leaves open the possibility that the presence of early Cucurbita at the Sharrow site represents the introduction of a cultivated plant into Maine during the mid-Holocene. Expand
Holocene landscape dynamics and long-term population trends in the Levant
This paper explores long-term trends in human population and vegetation change in the Levant from the early to the late Holocene in order to assess when and how human impact has shaped the region’sExpand
New radiocarbon dates and Late Palaeolithic diet at Wadi Kubbaniya, Egypt
Vegetable remains are a rarity in Palueolithic contexts. These new determinations on material from southern Egypt establish securely the date of an intensive grass-tuber and fish economy in the NileExpand


Accelerator radiocarbon dating of evidence for prehistoric horticulture in Illinois
With the development of direct detection radiocarbon dating, which uses an accelerator as part of a highly selective mass spectrometer, it is now possible to determine the age of milligram samples ofExpand
Radiocarbon dating: Some practical considerations for the archaeologist
Abstract The article is divided into four main sections in each of which a key aspect of radio-carbon dating is discussed with emphasis on the practical implications for users of dates. The fourExpand
14C dating of small archaeological samples: neolithic to iron age in the central alpine region
Accelerator mass spectrometry (AMS) radiocarbon 14C dating will widen enormously the range and scope of archaeological investigations. This is due mainly to 100- to 1000-fold sample size reductionExpand
Recent developments in archaeological dating using an accelerator
Abstract The main function of the Oxford Radiocarbon Accelerator Laboratory, to provide a continuing facility for archaeological dating, has been realised in the last few months. The current state ofExpand
Holocene age of the Yuha burial: direct radiocarbon determinations by accelerator mass spectrometry
The tandem accelerator mass spectrometer at the University of Arizona has been used and results indicate that the Yuha skeleton is of Holocene age, in agreement with the cultural context of the burial, and in disagreement with the previously assigned Pleistocene age of 19,000–23,000 yr. Expand
Working with Radiocarbon Dates
C-14 datings can not only provide us with estimates of the absolute age of objects or occupation layers, but also, when available in sufficient numbers, with initial and terminal datings for culturalExpand

Dates for Laguna woman and Los Angeles Man point to a much earlier presence of early man in America than had been thought, and independent amino acid racemization dates support these data. Expand
New radiocarbon dates on the cereals from wadi kubbaniya.
Finds at a Late Paleolithic site at Wadi Kubbaniya in Egypt suggest an early origin of food production, with implications for the initial development of complex societies. Expand

Accelerator mass spectrometry radiocarbon ages of amino acid extracts from Californian palaeoindian skeletons
Using accelerator mass spectrometry (AMS) to determine the radiocarbon ages of the amino acid extracts used in the original racemization studies indicates that some of the controversial Californian skeletons are in fact Holocene. Expand
