Tradition paleontological and biostratigraphic correlation methods are still perhaps the most common relative dating methods used by geologists.

More modern correlation technologies include use of marine stable isotope records, paleomagnetic dating, tephrachronology, geomorphological methods, sedimentation characteristics, and other geochemical and radiometric methods.

Geologists often need to know the age of material that they find.

They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.

Accurate dates also allow us to create sequences of evolutionary change and work out when species appeared or became extinct. These are: Where possible, several different methods are used and each method is repeated to confirm the results obtained and improve accuracy.

Relatively young deposits can be sometimes dated using tree rings, varved-lake sediments, coral growth patterns, and other methods.

Paleontology is the study of life in past geologic periods (fossil plants and animals), incorporating knowledge of an organism's phylogeny, relationships to existing organisms, and correlation to an established chronology of Earth History.

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.
