Bern Radiocarbon Dates V [PDF]

Radiocarbon, 1965
This list includes about half of the samples measured during the last year. Many studies need further investigation and the results will be published later when additional information will make better interpretations possible.The equipment and the technique is essentially the same as described earlier (Bern IV).Reliable results on CO2 samples extracted

Radiocarbon Dating of Bone [PDF]

Nature, 1967
SELLSTEDT et al.1 have described a method for the removal of inorganic carbonates from bone so that the residual collagen can be used as a source material for radiocarbon dating, and they conclude that this “offers the archaeologist an elegant and versatile tool which is likely to find wide application”.

Selection and Treatment of Data for Radiocarbon Calibration: An Update to the International Calibration (IntCal) Criteria [PDF]

, 2013
High-quality data from appropriate archives are needed for the continuing improvement of radiocarbon calibration curves. We discuss here the basic assumptions behind 14C dating that necessitate calibration and the relative strengths and weaknesses of ...

Towards a radiocarbon chronology of the Late-Glacial: Sample selection strategies [PDF]

, 2001
This paper outlines a dating program designed to test the reproducibility of radiocarbon dates on different materials of Late-Glacial age (plant macrofossils, fossil beetle remains, and the "humic" and "humin" chemical fractions of limnic sediments ...

Dating old hollow trees by applying a multistep tree-ring and radiocarbon procedure to trunk and exposed roots

MethodsX, 2018
In the process of dating the oldest trees, which are often hollow, we developed a new method that combines tree-ring cross dating and wiggle matching radiocarbon techniques on wood samples extracted from the stem and from exposed roots. The method can be
