Answer
Paleontologists determine the age of fossils using dating methods such as relative dating and absolute dating, including radiometric techniques.
Key Concept
Dating Methods
Explanation
Paleontologists use relative dating to determine if a fossil is older or younger than other fossils by its location in sedimentary rock layers. Absolute dating, such as radiometric dating, measures the decay of radioactive isotopes within the fossils or surrounding rocks to provide an approximate age in years.
