With a half-life of only 5730 years, carbon-14 dating has nothing to do with dating the geological ages! Hovind is confusing the carbon-14 "clock" with other radiometric "clocks." The only thing in the geologic record which has anything to do with calibrating carbon-14 dating is the coal from the Carboniferous Period.
Being ancient, the C-14 content has long since decayed away and that makes it useful in "zeroing" laboratory instruments. Hovind would take the trouble to do a little reading from something other than creationist publications he would not make such an outrageous statement.
By then, the relative ages (order) of the geologic column had already been worked out in some detail.

Then the paleontologists use the geologists' dates as evidence for the age of the fossils! The relative order of the strata was first determined by the principles of stratification. Beagle, a very strong Bible believer, made it a point to have a copy of Lyell's book for the ship's library.
(The principle of superposition was recognized as early as 1669 by Steno.) Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. Obviously, even Lyell was not pushing evolution at the time.
Why should the percentage of lead to uranium in zircon crystals (the key to ordinary uranium-lead, radiometric dating) depend on which geologic period they are found in?
If most of the geologic column were created during Noah's flood, would it really matter whether a zircon crystal was found in Cambrian strata or Cretaceous strata, in Jurassic strata or Tertiary strata?
Once the worth of index fossils had been established on the basis of stratification studies, they could logically be used to extend the correlation of rock formations to other continents.
At this point in time they were simply a useful tool for correlating rock formations.
Any kind of object clearly restricted to a specific point in the geologic column would do just fine.
If green dice were found only in the middle Ordovician strata, they would make excellent "index fossils." Evolution should be seen as an explanation of the faunal succession, a succession which was worked out long before evolution dominated the scene.
(Far from being a rubber stamp, radiometric dating would go on to revolutionize our understanding of the Precambrian.) Thus, it became possible to date strata directly from index fossils.
Note that evolution has nothing to do with how the index fossils are used to date strata!
(See Topic A1 for claims of bad dates.) Creationists, on the other hand, must explain to us how sediment and rock laid down in a mere year can yield such fantastic, orderly differences in radiometric ages.
