Here are the actual RC dates as found on the web site listed below the partial table.Would you simply focus on this one for us. What is the evidence and data for this dating?

The above was taken from www.dinosaurc14ages.com under carbon 14 dating topic.
Visit the above web site for details. The site is still under construction but is challenging academia to date the millions of dinosaur bones world-wide. Any takers on this thread? Some quick explanations:
(1) The youngest date of 2,560 +/- 70 RC years BP was the extracted contaminent from the alkali “pre-treatment” for the Hadrosaur from Montana. I worked part-time ifor three years in a small C-14 research lab as a chemist/sample preparer so I know a bit about C-14 dating. I will try and answer questions.
(2) The other RC dates were collagen or the Calcium carbonate fraction of bioapatite after purification pre-treatment or total organics as in the cases of the older date for the Triceratops and that for the Hadrosaur boe fragment from the North Slope of Alaska.
(3) Bio-apatite can be dated because carbonate replaces some of the phosphate portion of bones during the life time of the critter being tested for C-14. Therefore according to the labs, if concordant RC ages are obtained for both collagen the ages are valid. Concordant ages within 10 % were obtained.
(4) Also keep in mind that collagen proteins and soft pliable tissue should not last beyond 100,000 maximum.
