Since that time, CALIB, now renamed Int Cal, has been refined several times--as of this writing (January 2017), the program is now called Int Cal13.Int Cal combines and reinforces data from tree-rings, ice-cores, tephra, corals, and speleothems to come up with a significantly improved calibration set for c14 dates between 12,000 and 50,000 years ago.Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it.But there are many misconceptions about how radiocarbon works and how reliable a technique it is.Other organic data sets examined have included varves (layers in sedimentary rock which were laid down annually and contain organic materials, deep ocean corals, speleothems (cave deposits), and volcanic tephras; but there are problems with each of these methods.
C14 tells you when life ended, so for example: when the goat, sheep or cow died, to produce leather; when the papyrus died to make a page for writing. This means that C14 can tell you, within set limits, when the material for a manuscript became available to be made; it (alone) cannot tell you when a person wrote or drew upon it.
We should see some interesting results in the very near future.
The experts will tell you ‘yes’ within certain limits.
Trees maintain carbon 14 equilibrium in their growth rings—and trees produce a ring for every year they are alive.
Although we don't have any 50,000-year-old trees, we do have overlapping tree ring sets back to 12,594 years.
