While true, fossils are buried with plenty of clues that allow us to reconstruct their history. Your email address is used to log in and will not be shared or sold. Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating.

Each are is identified by its atomic masswhich and the number of protons fossil neutrons. Radiometric datingradioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed. Geologists often need to know the age of material that they find. Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
