Crossdating

Crossdating is a method used by scientists to determine the ages of wood samples or archaeological findings by comparing their growth patterns, called tree rings, to those of other samples. Each tree ring's width varies based on environmental conditions during that year. By matching these patterns across multiple samples, researchers can establish a precise timeline, even for very old or complex specimens. This technique is essential for accurate dating in fields like archaeology and climate research, helping to reconstruct historical events and environmental changes with high reliability.
