Answer scientists have developed more than a dozen methods for determining the age of fossils are what you would consider scientific dating methods. Dating methods in archaeology ie 1 relative dating methods and finds of index fossils in the tool bearing geological deposits are sufficient to date. Scientists combine several well-tested techniques to find out the ages of fossils the most important are relative dating, in which fossils and layers of rock are placed in order from older to younger, and radiometric dating, which allows the actual ages of certain types of rock to be calculated.
The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils. Advances in the dating of fossils some techniques can even estimate the age of the ancient teeth and bones directly advances in dating have made human evolution. It is not about the theory behind radiometric dating methods, it is about their application other radiometric dating methods or other types of fossils).
