Paleontologist have to analyze the fossil evidence that they find and compare it with other discoveries in order to grasp its meaning and importance.

Relative dating stems from the idea that something is younger or older relative to something else.
It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.
