The age of fossils can be determined using radiocarbon dating (also known as carbon-14 dating), stratigraphy, and biostratigraphy.

*Determining the ages of fossils is an important step in mapping out how life evolved across geologic time.
*The study of stratiography enables scientists to determine the age of a fossil if they know the age of layers of rock that surround it.
*Biostratiography enables scientists to match rocks with particular fossils to other rocks with those fossils to determine age.
*Paleontology seeks to map out how life evolved across geologic time. A substantial hurdle is the difficulty of working out fossil ages.
*Scientists use carbon dating when determining the age of fossils that are less than 60,000 years old and composed of organic materials such as wood or leather.
