50,000-year-old trees, we do have overlapping tree ring sets back to 12,594 years. A complete terrestrial radiocarbon record for.2.8 kyr.P. Must be in the area where trees dating suisse romande produce defined rings. What you need is a ruler, a reliable map to the reservoir: in other words, an organic set of objects that you can securely pin a date on, measure its C14 content and thus establish the baseline reservoir in a given year.

High-Precision Radiocarbon Age Calibration for Terrestrial and Marine Samples. For example, in IntCal09's calibration, they discovered evidence that during the Younger Dryas (12,550-12,900 cal BP there was a shutdown or at least a steep reduction of the North Atlantic Deep Water formation, which was surely a reflection of climate change; they had to throw. IntCal 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. Stuiver M, and Reimer. How Does Radiocarbon Work?
We should see some interesting results in the very near future. The Search for Calibrations, as you might imagine, scientists have been attempting to discover other organic devotions for dating couples objects that can be dated securely steadily since Libby's discovery. 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.
