Cross correlation dating techniques

Keyed to the relative time scale are examples of index fossils, the forms of life which existed during limited periods of geologic time and thus are used as guides to the age of the rocks in which they are preserved.

William "Strata" Smith, a civil engineer and surveyor, was well acquainted with areas in southern England where "limestone and shales are layered like slices of bread and butter." His hobby of collecting and cataloging fossil shells from these rocks led to the discovery that certain layers contained fossils unlike those in other layers.

Dating is not necessary to demonstrate that evolution is a fact.

Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.

A few examples of such lies are presented at the very bottom of this page.

Many of these links also appear where appropriate below.

James Hutton and William Smith advanced the concept of geologic time and strengthened the belief in an ancient world.

For each dating or chronological method there is a link in the box at right to take you to that section of this page.

There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.

The Carbon14 technique has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine. Isochron methods avoid the problems which can potentially result during radiometric testing.

Using these key or index fossils as markers, Smith could identify a particular layer of rock wherever it was exposed.
