The oldest fossils are usually found in the bottom of the rock strata. This is only true for undisturbed layers.
There are two ways of finding a fossils age, relative dating and absolute dating. Relative dating is when you use other fossils, which you know the age of, to compare another fossil with it to find out its age. Absolute dating is when you use radioactive dating to find the age of a fossil. This is to find the precise age of It.
Radioactive Dating: Used to trace when the material was made or created
