They thought that sites which had the same kinds of pots and tools would be the same age.

During the lifetime of an organism, the amount of c14 in the tissues remains at an equilibrium since the loss (through radioactive decay) is balanced by the gain (through uptake via photosynthesis or consumption of organically fixed carbon).

However, when the organism dies, the amount of c14 declines such that the longer the time since death the lower the levels of c14 in organic tissue.

Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.

In Nyerup's time, archaeologists could date the past only by using recorded histories, which in Europe were based mainly on the Egyptian calendar.

Methuselah's tree ring sequence near its core -- when it was a young tree -- was matched to the sequence found in pieces of nearby trees which had died previously. Henry Michael of the University of Pennsylvania's Museum Applied Science Center for Archaeology (MASCA) scanned the area almost every summer for over three decades.
