Mg dating support

post-glacial recolonization events) of the last 50,000 years.

In effect, they provide us with windows to past societies, and contribute to our knowledge of ancient human evolution and cultural development.

These results open the way for the routine dating of small or key bone samples. bones, teeth, antler and ivory) found in the fossil record have a tremendous informative potential relevant to the fields of archaeology, palaeoecology and the history of art and technology.

Because they can be identified to the species level and radiocarbon dated, these fossil remains are key to establishing the archaeological chronologies, palaeoenvironmental reconstructions and historical-biogeographical processes (i.e.

0.3%) resulting in uncertainties that are unacceptable for most archaeological samples.In practice, the manipulation of small bone samples presents several obstacles which are difficult to overcome, especially for ancient (Middle to Upper Paleolithic transition) samples.Recent advances in graphite sample preparation and AMS capabilities make it possible to now run very small samples (.They can be run in triplicates in order to improve the precision, but this requires the initial sample size to be increased, thus decreasing the interest of the gas ion source for archaeological samples.Here, we present the first radiocarbon dates obtained from minute amounts of bone (3–60 mg) using ECHo MICADAS, the compact AMS recently installed at Gif-sur-Yvette, France.
