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

Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.

Also includes info on how fossils are formed, the “cleaning, preparing, & repairing” of fossils, and other useful resources.

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.

The unstable or more commonly known radioactive isotopes break down by radioactive decay into other isotopes.

Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.

The list is too long to mention here, so a couple of examples are provided to get you going on your search for programs in your area: Explore U. fossil collecting locations that are detailed on this site.

A key point is that it is no longer necessary simply to accept one chemical determination of a rock’s age.

Age estimates can be cross-tested by using different isotope pairs.

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

Darwin and his contemporaries could never have imagined the improvements in resolution of stratigraphy that have come since 1859, nor guessed what fossils were to be found in the southern continents, nor predicted the huge increase in the number of amateur and professional paleontologists worldwide.

If the fossils, or the dating of the fossils, could be shown to be inaccurate, all such information would have to be rejected as unsafe.
