Dating a dinosaur bone
Some of the calculated "ages," though, lined up with the already assumed age of 64 million years, and these data were hand-picked to represent the "age" of the fossil.
Thus, the technique was called "the first successful direct dating of fossil vertebrate bone"—a classic case of circular reasoning.
We know how quickly C14 decays, and so it becomes possible to measure how long it has been since the plant or animal died." It seems what creationists fail to understand is dinosaur bones are permineralized or at the very least, partially permineralized, and therefore they no longer qualify as "once living material." Once the original material has been replaced with minerals it cannot be dated using the Carbon 14 method.
Even soft tissue has shown to be preserved with minerals such as iron rendering the method useless for dating.
Here is a brief explanation of how the method works from ray protons blast nuclei in the upper atmosphere, producing neutrons which in turn bombard nitrogen, the major constituent of the atmosphere .
If any collagen whatever is still in the bone, this would falsify their evolution-friendly "age." Also, collagen contains carbon.
Thus, if collagen is present, the bones could be carbon-dated.
Amazingly, it was dated at millions of years older than the sedimentary rocks The data from one of the San Juan Basin dinosaur limb bones showed a range of "ages" from roughly 15 to 85 million years.
The authors tried to explain away the younger-looking numbers by writing in their report in Thus, it was taken on faith that the data indicating a younger age do not represent the real age, but instead represent the age of some event whereby uranium was supposedly added to the dinosaur bone millions of years after it had been encased in its Cretaceous sandstone formation.

They used a new laser technique to measure radioisotopes in the bone, yielding an age of millions of years.
