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.

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods.
Relative fossil dating is different from absolute dating, in one important way: Absolute dating gives you a number for example, carbon dating a fossil to 50 million years ago. Relative dating puts the fossil in contextwhat lived before it, and what lived after. Relative dating relates fossils to events. These events may be paleontological relating to ancient life, like dinosaur extinction ; geographical relating to earth and natural environment, like eruptions and the Ice Age ; and archaeological relating to ancient society and structures, like the appearance of the Maya. Relative fossil dating of ancient species relies upon stratigraphy.
