Relative Techniques. In the past, relative dating methods often were the only ones available to paleoanthropologists. As a result, it was difficult to chronologically compare fossils from different parts of the world. However, relative methods are still very useful for relating finds from the same or nearby sites with similar geological histories.
7.1: Relative Dating
Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique. Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate.
