I've had three unsuccessful attempts at posting an answer to this, Ray, which failed owing to the technical shortcomings of whatever widget I am trying to use, so I apologise for the tardiness.
I believe Le Grand Harshman and I are saying the same thing: measuring the age of fossils is irrelevant to measuring the age of the Earth because the accepted method for measuring the age of fossils (beyond the 50K year limit imposed by the short half-life of C14) is to use radiometric dating on igneous rocks "nearby" to the fossil. Hence, you don't need the fossil to date the age of the Earth, you just need the oldest rocks available, whether or not there are fossils stratigraphically nearby.

You mentioned carbon dating in relation to the age of the Earth, not me.

The "age of the fossil" simply puts a stake in the ground that reads "the Earth must be older than this nearby igneous rock".

See above, if you want to date the Earth, sample and date igneous rocks. The oldest estimate will give you a minimum value of the age.

As I mentioned elsewhere, if radiometric dating of igneous rocks is unreliable, then what basis do you have to say that the Earth is "old"?

I have no knowledge of what scientific protocol was followed in attempting to date the shroud, so it is difficult to answer any conspiracy theory you may want to propose.
My only point is that the method used to carbon-date a sample routinely provides results that correlate reliably from independent tests if properly applied. This tells you nothing about whether the sample is faked or not.

Don't know to what you are referring. Standard carbon-dating methods will include caveats such as "do not attempt to carbon-date living tissue" and "make sure that your sample doesn't come from an environment where C14 or C12 are differentially enhanced or leached. What are the "certain materials" to which you refer?

No, sorry - you go first. What do you mean by "species immutability", "fixism" or "permanence"? I ask because you seem to be particularly concerned about the definition of words.

All I can say to this is that you seem to want to constrain the omnipotence of your deity. I am happy to stand back and wait for the thunderclap and flash of lightning. But I am also happy to leave the theology up to you.

See above, please provide a simple language definition of "species immutability". Perhaps I missed it in your previous posts.
