Why don’t those who have found collagen in dinosaur bones date them?
THE BARBARIAN response: For the same reason you don’t take the temp of a blast furnace with a candy thermometer. You’ll get 200 degrees. Likewise, if you date extremely old carbon by C-14, it will just peg out at whatever the maximum date is for that particular system.
You need to get an updated list of creationist stories. You’re recycling ones that they gave up on long ago.

Carbon content of Bones With and Without Preservative – Shellac
- Edmontosaur 51.8 – three coats Not dated
Ibid 18.1 - one coat Not dated
Ibid 2.7 uncoated Not dated
Conclusion: The uncoated Edmontosaur Dinosaur bone fragment was in the same carbon % range as dinosaurs 1-5. Had they had even only one coat of shellac there would have ben about 1* % carbon in the scrapings, apparently were uncoated and therefore NOT contaminated by shellac which can promote a young age. Therefore the above dates appear to be accurate RC ages for RC dating bone apatite (no collagen). The organic carbone in the “special case” Hadrosaur sample was probably collagen but was reported as organic material. Note that both the alkali residue
from the bone is the purified organic material and the humic acid the contaminant [gave an older date]. This sample was added to show that both the bioapatite of dinosaur bones and organic material give RC dates well within the range of C-14. I have copies of all these reports.
Collagen was not found in samples 1-5 so only bioapatite of these bone fragments were tested for C-14; normal lab procedure is to treat with dilute acetic acid overnight at a high temperature to remove superficial old or young carbonates. I would assume that the Un. of AZ would have performed that treatment so these dates are accurate.
Correction for my lsat posts: The range for the conventional Beta method can be extended to about 43,000 RC years if you ask the lab to do a more expensive long count on the conventional Beta system but certainly not much above that. The range I gave should have read Conventional AMS at up to 51,000 RC years. Sorry about that I left out the letters AMS. I hope all this is helpful to understand a little bit more about C-14 dating and the fact that such dates are falsifying the thkeory of macroevolution.
