Neutrinos penetrate the earth so easily that they would affect all strata more or less equally, to the extent that they affect anything at all. The Cambrian has simply been around a lot longer than the Cretaceous, and the radioactive uranium in its zircon crystals has had more time to decay into lead. These fossils serve as a reminder that taxonomic divisions are human constructs that have been imposed in hindsight on a continuum of variation. It's like a dictionary listing the more important English words. Obviously, even Lyell was not pushing evolution at the time.

Thus, it became possible to date strata directly from index fossils. It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata. They can easily be mistaken for real fossils.

In some cases, burial might well be less than instantaneous. Wood is usually the part of a plant that is best preserved and most easily found.

Perhaps, by the time Noah's flood started, the decay rate had started to slow down dramatically. They must now assume that the decay rates were low before Noah's flood, that they became phenomenally high during the start of Noah's flood, and that they dropped to normal after Noah's flood. Russel, who wrote an article in Chemical and Engineering News Oct. Fresh zircon crystals are lead-free, because lead just doesn't fit in very well with their crystallization process. Even creationists realize that time is the only answer, but they give that answer a strange twist.

None of these charges amount to a hill of discarded beans. Fossil wood may or may not be petrified. Subfossils are often found in caves or other shelters where they can be preserved for thousands of years. In order to collect the point, creationists must show that polystrate fossils exist where they shouldn't be. Studies done on the European continent soon demonstrated the universal validity of index fossils.

The relative order of the strata was first determined by the principles of stratification. The internal structure of the tree and bark are maintained in the permineralization process. Uranium is radioactive and eventually decays into lead, which is trapped in the zircon crystal. As the Transverse Ranges were being folded and pushed up, the sea floor on which our whale had settled and, in time, had been buried, was now subject to folding.
