K–Ar dating was used to calibrate the geomagnetic polarity time scale.

It is possible, particularly in dry, desert climates, for organic materials such as from dead trees to remain in their natural state for hundreds of years before people use them as firewood or building materials, after which they become part of the archaeological record.The development of accelerator mass spectrometry (AMS) dating, which allows a date to be obtained from a very small sample, has been very useful in this regard.Other radiometric dating techniques are available for earlier periods.Thus dating that particular tree does not necessarily indicate when the fire burned or the structure was built.For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating.
