Preparation of bones for radiocarbon dating is still quite a challenge for researchers. The methods are being tested and improved, to obtain better and better results and to verify the previous ones. In this work, a set of collagen samples, extracted in 2018 from Cervus elaphus bones and antlers from various sites in Europe, was subjected to re-treatment using ultrafiltration in Gliwice Radiocarbon Laboratory. The samples tested had a wide range of ages, from older than 40 000 14C years BP to modern. The material prepared in this way was subjected to the measurement of C/N atomic ratios and radiocarbon dating using the AMS technique. Also, the stable isotopes (δ13C and δ15N) values were determined. A compilation of the obtained results is presented in this work.
