Prior to the development of radiocarbon dating , it was difficult to tell when an archaeological artifact came from. Unless something was obviously attributable to a specific year -- say a dated coin or known piece of artwork -- then whoever discovered it had to do quite a bit of guesstimating to get a proper age for the item. The excavator might employ relative dating, using objects located stratigraphically read: buried at the same depth close to each other, or he or she might compare historical styles to see if there were similarities to a previous find. But by using these imprecise methods, archeologists were often way off. Fortunately, Willard Libby, a scientist who would later win the Nobel Prize in Chemistry, developed the process known as radiocarbon dating in the late s. It's still the most commonly used method today.

Radio Carbon Dating

The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. Sometimes only one method is possible, reducing the confidence researchers have in the results. Kidding aside, dating a find is crucial for understanding its significance and relation to other fossils or artifacts. Methods fall into one of two categories: relative or absolute. Before more precise absolute dating tools were possible, researchers used a variety of comparative approaches called relative dating. These methods — some of which are still used today — provide only an approximate spot within a previously established sequence: Think of it as ordering rather than dating. Biostratigraphy: One of the first and most basic scientific dating methods is also one of the easiest to understand.
