There are actually ten principals used by paleontologists to do relative dating. They are:The Principal of UniformitarianismThe Principal of Intrusive relationshipsThe Principal of Cross-cutting relationshipsThe Principal of Inclusions and componentsThe Principal of HorizontalityThe Principal of SuperpositionThe Principal of Faunal successionThe Principal of Lateral continuityThe Principal of Inclusions of Igneous rocksandThe Principal of Included fragments

Paleontologists can determine the age of a fossil by using relative dating techniques, such as examining the position of the fossil in relation to surrounding rock layers, or by using absolute dating methods, such as radiometric dating to determine the actual numerical age of the fossil based on the decay of radioactive isotopes within it.
Depending on the size of the fossil, anything from a micrometre to a metre.
