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.If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them.He said that his team and the laboratories they employed took special care to avoid contamination.That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.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.A research team from the CRSEF, or Creation Research, Science Education Foundation, led by Hugh Miller, has claimed to have dated dinosaur bones using radiocarbon methods, determining them to be no older than several dozens of thousands of years old.
Consequently equally small quantities of modern carbon can severely skew the measurements.
Dinosaurs are not dated with Carbon-14, yet some researchers have claimed that there is still Carbon-14 in the bones. Do these data indicate that a more accurate method needs to be derived?
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.
In the article by Leppert, we find: Hugh Miller generously provided me with a copy of the elemental analysis of one of their dinosaur fossils.
Daniel Fisher of the University of Michigan’s Museum of Paleontology examined these results and concludes that there is nothing whatsoever extraordinary about them.
