Age of deposition should not be confused with the date of material enclosed in deposit.Cross dating involves comparing similar artifacts from similar sites that may be of similar age.

Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.

The discovery of means for absolute dating in the early 1900s was a huge advance.

The methods are all based on radioactive decay: The first radiometric dates, generated about 1920, showed that the Earth was hundreds of millions, or billions, of years old.

In the past 150 years they have not found any fossils that Darwin would not have expected.

New discoveries have filled in the gaps, and shown us in unimaginable detail the shape of the great ‘tree of life’.
