Fossil record radiometric dating

Radiometric dating (often called radioactive dating) is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

Surprisingly there are quite a few problems with the geologic column itself being a representation of millions of years of Earth’s history.

The standard approach to looking at fossils in the geological column is to assume that lower is older.

Since the geologic column represents millions of years of Earth’s history, then obviously the fossils in each of the layers must be the same age as the layer in which they are found.

Since each of these layers seems so specialized it is easy to conclude that one type of creature gave rise to the next type of creature over the course of whatever time it took to form the various layers between them.
