Dating of dinosaurs bones
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.

A trio of geologists has published what they called the first successful direct dating of dinosaur bone.
They used a new laser technique to measure radioisotopes in the bone, yielding an age of millions of years.
One clue that they are broken comes from the evolutionary age disagreements that characterize the whole field of radioisotope dating.
For example, an igneous rock from the Grand Canyon—which, unlike sedimentary rock, is a type of rock that has been considered "datable" because the relevant isotopes are locked up in its tiny crystals—was tested by standard means.
Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs.
"Comparing such different molecules as minerals and organics from the same bone region, we obtained concordant C-14 results which were well below the upper limits of C-14 dating.
Neither collagen nor radiocarbon was tested in these dinosaur bones.
Instead of hand-picking data points from a broken radiodating system and calling that a "successful" determination of age, why not take the scientific high road to legitimacy and perform cross-checks with alternative natural processes? Any indication that these dinosaur bones are not millions of years old might call the whole evolutionary picture into question, and might therefore offer evidence for a recent creation.
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.
