If the rock is indeed millions of years old, then like blood’s heme pigments, oil’s organic, carbon-rich molecules should have completely degraded long ago—especially considering the voracious nature of oil-eating bacteria.

I happened to catch a great tweet by Michael Shermer.
In fact, he specifically states that if you use age to define the fossils, you can’t use them for dating the rock. This is just the latest in another long line creationist misrepresentation. First, you need a type of fossil that is common, widely distributed, and easily identified at the species level.
There are several groups that meet these criteria; ammonites, trilobites, corals, for example.
But in standard studies, no age assignment is ever accepted unless it conforms to the "millions of years" doctrine of evolutionary earth history.
pointed out one of the big problems with this dating approach by saying that the past "methods are far from perfect: it is difficult to gain accurate depositional ages for sedimentary rocks, and matters can be further complicated when millions of years of geologic and environmental forces cause erosion of fossil-bearing strata." They highlighted its "success" by contrasting it with the lack of success of prior dating techniques.
Will this new radioisotope dating (or radiodating) technique solve the problems that plagued older dating methods?
If history is anything to go by, then the answer is no.
Apparently there was some back and forth about some fossils with Carl Zimmer.
Anyway, Don Prothero commented about it and this is a great quote for a variety of reasons.
Igneous rock layers can supposedly be directly dated, so sedimentary layers sandwiched between them are interpreted to have been deposited in between the "ages" assigned to the igneous rocks.
