Index fossils dating


by Gordon Howard Evolutionary paleontologists use ‘index fossils’ to assign an age to a layer of sedimentary rock and its associated fossils.Evolutionary theory assumes that a particular creature evolved from its ancestors, lived successfully for a period, then became extinct as its descendants evolved better ways of surviving.

Consequently, the ‘evolutionary life-span’ allotted by evolutionists for many index fossils has continually been increasing, as examples are found in rocks of different assigned ‘ages’.

Another factor that challenges the million-year ages produced by these dating methods is the absence of evolutionary change in many organisms over these vast periods, a phenomenon that is even given a name—stasis.

The basis of cross-dating is the occurrence of finds in association.

The assumption is that a particular type of artifact, for example a type of sword, when found in an undated context will bear a similar date to one found in a dated context, thus enabling the whole of the undated context to be given a chronological value.

Different layers would contain fossils transported from different ecosystems rather than different evolutionary time periods, completely destroying the idea that index fossils represent different evolutionary ‘ages’.
