These tests have consistently given the same ages for each of these objects.Examples of a number of consistent dates derived from different methods are given.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.[ While this may be true, a shrub in Tasmania could be 40,000 years old.
There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.The most compelling argument for an age of the earth of 4.5 billion years are the large number of independent tests that have been used to confirm this date.
