The fast, high-throughput distinction between paleoanthropological remains and recent forensic/clinical bone samples is of vital importance in the field of medicolegal science. In this paper, a novel screening method has been described, using the crystallinity index (C.I.) and carbonate-phosphate index (C/P) as a means to distinguish between archeological and forensic anthropological skeletal findings. According to the Fourier transform infrared spectroscopy analyses, the archeological bone samples are characterized by a range of C.I. between 2.84 and 3.78 and by low C/P values of 0.10-0.33, while the C.I. and C/P ranges of forensic skeletal remains are 2.55-3.18 and 0.38-0.88, respectively. Significant (p < 0.05) changes were observed in C/P as well as C.I. values between the groups of forensic and archeological skeletal samples. The suggested dating method needs only a few milligramms of bone tissue; thus, it can be extremely useful for distiguishing ancient and recent bone fragments.
