This type of froms when a buried organism decays and leaves behind only a thin layer of carbon.
Petrified wood is an example of this type of fossil.
This type of fossil may consist of all or part of the original organism. Amber is an example.

Suggests that all of Earth's physical processes, such as erosion, happen at the same rate in the present as in the past.

Attempts to date rocks or fossils by their location within layers of rocks.
Attempts to date rocks or fossils by measuring the amounts of stable and unstable isotopes within them.
Illustrates how accumulating mutations actually make organisms less fit for survival.
