Dating of two Paleolithic human fossil bones from Romania by accelerator mass spectrometry

In this study we have dated two human fossil remains found in Romania, by the method of radiocarbon using the technique of the accelerator mass spectrometry. The human fossil remains from Woman's cave, Baia deFier, have been dated to the age 30150 $\pm$ 800 years BP, and the skull from the Cioclovina cave has been dated to the age 29000 $\pm$ 700 years BP. These are the most ancient dated till now human fossil remains from Romania, possibly belonging to the upper Paleolithic, the Aurignacian period.

Analysis of a Fossil Bone from the Archaeological Settlement Malu Rosu, Romania by Accelerator Mass Spectrometry

A fossil bone from the archaeological site Malu Rosu Giurgiu, in Romania has been analyzed by accelerator mass spectrometry to estimate its age by determining its $^{14}$C content. The radiocarbon age of the bone is in agreement with the date obtained by the method for age determination, based on fluorine content. This is the first radiocarbon dating for the final Neolithic period, for this archaeological settlement in the Romanian region.
