Various relative and absolute dating techniques used by anthropologists
Having an accurate time scale is a crucial aspect of reconstructing how anatomical and behavioral characteristics of early hominids evolved. Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object. It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years. The most common relative dating method is stratigraphy. Other methods include fluorine dating, nitrogen dating, association with bones of extinct fauna, association with certain pollen profiles, association with geological features such as beaches, terraces and river meanders, and the establishment of cultural seriations. Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.

Archaeology and archaeologists are portrayed in the mass media as scientists, treasure hunters, adventures, harmless eccentrics, or murderers. Newspaper and magazine articles describe the latest scientific discoveries by archaeologists. Movies, such as the Indiana Jones series, portray the archaeologist as adventurers pursuing treasures and fame. Mystery novels by Tony Hillerman, Agatha Christy, and others present tales of murder and intrigue on archaeological digs in exotic settings. Despite the high level of media attention that archaeology receives, seldom do we encounter accurate presentations of what archaeologists are attempting to accomplish and how archaeology is done.
The ability to precisely date, or identify the age of an object, can teach us when Earth formed, help reveal past climates and tell us how early humans lived. So how do scientists do it? Radiocarbon dating is the most common method by far, according to experts. This method involves measuring quantities of carbon, a radioactive carbon isotope — or version of an atom with a different number of neutrons.
