This works better in temperate areas that have more distinct growing seasons (and this rings) and relatively long-lived tree species to provide a baseline.

Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object.

It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.

The development of Atomic Absorption Mass Spectrometry in recent years, a technique that allows one to count the individual atoms of 14C remaining in a sample instead of measuring the radioactive decay of the 14C, has considerably broadened the applicability of radiocarbon dating because it is now possible to date much smaller samples, as small as a grain of rice, for example.

Dendrochronology is another archaeological dating technique in which tree rings are used to date pieces of wood to the exact year in which they were cut down.

I’ve been told by a lot of parents that this post absolutely pertains to teen girls as well! I didn’t mean to leave them out, I just don’t have any girls so I didn’t feel qualified to claim that!

    This latest i Tunes works fine on the Mac by the way, so if you use a Mac it is safe to update. When I tried updating to the newest i Tunes for Windows, a few days ago, I had errors too, both during the installation and when I tried to start the program, and the errors here were something to do with mobile device support. ITunes opened up normally, my library was there in full, and I've had no trouble since.
