The method was tested on two dendrochronological series from Scythian barrows of known age in Southern Siberia: the Pazyryk barrows (the Altai Mountains) and the Dogee-Baary-2 burials (Western Sayan Mountains) separated by 450 km.The analysis has shown that the Pazyryk barrow is younger by 80 or -4 yr than the Dogee-Baary-2 burials.

A fish caught in hard water has thus a higher Carbon-14 age than contemporaneous terrestrial samples.If such a fish is then cooked in a ceramic pot, the radiocarbon age of the food crust will be higher than if a terrestrial animal was cooked in the pot.This is known as the “reservoir effect” because the fish’s carbon actually comes from another “reservoir” than the carbon in terrestrial animals from the surrounding area.Radiocarbon dating tweaked Libby was wrong about two things.First, the half-life of 14C is actually 5,730 years, and second, he believed that the carbon content of the atmosphere was constant, whereas it is now known that atmospheric carbon levels have varied somewhat over time.
