The preferred method of dating dinosaur fossils is with the radiometric dating method.
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.
At a horizon of 40,000 years the amount of carbon 14 in a bone or a piece of charcoal can be truly minute: such a specimen may contain only a few thousand 14C atoms.
Consequently equally small quantities of modern carbon can severely skew the measurements.
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.
Let's look at their research methodology in detail (indicated by bullet points): Let's take a little pause to consider the general issue of misrepresenting your own research. did this, since there would have been a slim chance (at best) of the museum curator providing them with any dinosaur bone fragments if he or she had known what the true intent of the supposed chemists was.
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.
Nowadays, the most common products used in restoration are of synthetic origin.
Being these resins obtained from fossil oil, they are devoid of 14C.
Therefore, a not complete removal from the sample to be dated can be the cause of a consistent apparent ageing of the dated artworks.
A chemical pre-treatment is required in order to clean the samples before the measurements.
The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods, at some age which is a lot below the 'usual' i.e.
