Best suited to the carbon 14 dating technique st petersburg dating service
Members of the Paleochronology group presented their findings at the 2012 Western Pacific Geophysics Meeting in Singapore, August 13-17, a conference of the American Geophysical Union (AGU) and the Asia Oceania Geosciences Society (AOGS).
Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.
In order to do this, you need to measure various isotopes of uranium .
So the million year old object was incorrectly dated using a decay series not suited to it.
This is then transformed into isotopic ratios and then used to date the material.
The machinery you use has to be tuned and calibrated to which isotopes you want to measure and needs to be set with the correct running conditions.
It's accuracy has been verified by using C-14 to date artifacts whose age is known historically.
The fluctuation of the amount of C-14 in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter from soils poses a greater possibility for error. Thomas Seiler, a physicist from Germany, gave the presentation in Singapore.
