And the result of this accepted method dates dinosaur fossils to around 68 million years old. Its half-life ($t_$) is only 5,730 years—that is, every 5,730 years, half of it decays away.
The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years.
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.
He said that his team and the laboratories they employed took special care to avoid contamination.
A substantial hurdle is the difficulty of working out fossil ages.By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.What solutions are available for increasing accuracy of the tests? From the source linked above: Carbon-14 is considered to be a highly reliable dating technique.It's accuracy has been verified by using C-14 to date artifacts whose age is known historically.
