The atoms in some chemical elements have different forms, called isotopes.

There are two main methods determining a fossils age, relative dating and absolute dating.

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

Relative Dating Before the 20th cent., archaeologists and geologists were largely limited to the use of relative dating techniques.

Estimates of the absolute age of prehistoric and geological events and remains amounted to little more than inspired guesswork, as there was no scientific basis for testing such proposals.
