It can be used to date a sample of dead material up to about 60,000 years old. The technique dramatically helped archaeology as it was possible to accurately date samples for the first time.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cb\u003eBuy once, print forever!\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYour students make their paper models out of the colourful parts.
