Re: Rebuttal of Article Should Go Here
Please do it systematically, point by point or paragraph by paragraph, otherwise it just looks like a Gish Gallop. Start with the first paragraph. I'm here to learn from the experts.

First paragraph.

quote:
Carbon 14 dating of bone is one of the most difficult tasks for carbon dating and requires the most care of any carbonaceous material. This is mainly due to the nature of bone which is a very porous material. Certain parts of bone look like a sponge under microscopic examination. Many dinosaur bones are hard as rock because the original material has been replaced with silicon materials such as quartz. We have found un-mineralized dinosaur bones. We can then scrape the outer surface off to get rid of surface contamination and date the inner remaining material. Depending on other factors one can choose to date just the purified bioapatite, total organics or collagen. One can also date all three components as was done by us (see chart below).

They, themselves claim to have found 'un-mineralized dinosaur bones'.

Really? Where did they publish their findings? Any references for this or are they just making things up as they go?

They could become famous if they did; look at what happened to Dr. Mary Schweitzer and her team. They didn't even find "un-mineralized" dinosaur fossils, those fossils they found were mineralized.

So, if your source can provide the verifiable evidence for their find, we could go on. Else we can just ignore it as another huge untruth told by clowns with an agenda.

Re: One rebuttal
Yes, I was wondering as well, as 14C can also be produced in other ways, for example from the stable isotope 13C through neutron reactions.

I will thus expect to see 14C in a lot of diamonds as it can constantly be produced in those diamond crystals, depending on the proximity to some radioactive sources.

Maybe the 14C produced in this way can't be detected due to the low concentrations.

Maybe I've got it wrong. Maybe Coyote can enlighten us on the subject.

I'm no wizz on radioactivity; my knowledge on this subject borders on dangerous; therefore will take the word of experts on this.

(Real experts, not the pretend "experts" who claim that you can use carbon dating on diamonds!)

Re: One rebuttal
Thanks Coyote, I'll do that relatively soon. The salt mines are calling.

People here asked for evidence for their claims. Not for arguments. Anyone can make any claim about anything and everything.

Unfortunately for you, that's all your references had. Claims.
