Methods of radiometric dating livewire dating
However, by itself a fossil has little meaning unless it is placed within some context.
The age of the fossil must be determined so it can be compared to other fossil species from the same time period.
For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.
By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.
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.

For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).
Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.
