By then, the relative ages (order) of the geologic column had already been worked out in some detail.Radiometric dating would later confirm the relative ages of the strata and tie them to absolute dates.The depth of burial, itself, has little to do with our mystery.In some parts of the world the Cretaceous is found deeper than is the Cambrian in other parts of the world.Evolution, working in tandem with geologic ages, can explain why we have index fossils, but evolution is needed to make the index fossils useful for dating strata.While we're on this subject, you might wish to know the odds of arranging the Precambrian era, the seven geologic periods of the Paleozoic (Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Permian), the three periods of the Mesozoic (Triassic, Jurassic, Cretaceous), and the two periods of the Cenozoic (Paleogene, Neogene or Tertiary, Quaternary) in their proper order by pure chance. 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.
Nearly a half-century would pass before Darwin's book, The Origin of Species, was published!
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.
(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.
This poses a fatal problem whether one believes in the accuracy of radiometric dating or not!
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?
