Well if it was deep in the ground it was probably old.

Scientist find evidence about common ancestors.
Palaeontologists are scientists who study fossils.
For relatively recent fossils, dating by carbon 14 is the most accurate method. For older fossils it is necessary to analyse the geological layer in which they are found; fossils located in an undisturbed geological layer of a certain age, are the same age as the layer in which they are found, necessarily.
scientists use carbon dating to tell how old fossils are. They can also tell how old it is by using relative dating (for example): if a fossil is found deeper in the ground than another fossil, it is older.

Their fossils (bones).
They find fossils inside their bum
They pull there heads out of there butts,clean the poopy off there head and dig in the ground to find the dang fossils.
They've found PLENTY.
Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.

because sometimes the scientists don't find the fossils
Scientists get information about dinosaurs from fossils and they are able to trace DNA and find out how dinosaurs looked, ate, hunted and lived.
Carbon 14 is not normally used to determine the age of fossils as it has such a short half-life. Most fossils found are well over 50,000 to 60,000 years old which is the maximum age at which Carbon 14 can be used. Potassium/Argon and Uranium/Lead are much more commonly used.
