I actually happen to know something about the "Miller Tale" as it is called. Miller "borrowed" some dinosaur bones from a museum without telling the curators or owners what he was actually intending on doing with it. He immediately took it to be 14C dated and received a date of roughly 40,000 years. So if Dinosaur bones are supposedly 65+ million years old, why is this? I'll tell you why.
The dinosaur bones did NOT have any carbon in them. They'd been essentially completely replaced by minerals during the fossilization process. What happened was that Miller did NOT know that they were covered in a preservative made of an organic material called shellac, which is organic so it's full of carbon. This contaminated the result. What they got was a date for the shellac, not the dinosaur fossils.
