A new method of cross-dating of wood samples is suggested. Based on the classical methods of spectral estimating, it uses the average cross-spectral density as a function of relative position of series. This procedure being not sensitive to phase shifts in data may be instrumental for the cross-dating of samples originating from different areas. The method was tested on Scythian tombs located in Southern Siberia, Central Asia and Kazakhstan, with the emphasis on the "Royal" barrows which included well preserved wood structures. For well-preserved timber samples, the accuracy in relative age estimations can reach a single year. The wiggle matching method has been used for a reliable assessment of the calendar-scale time.
