Relative dating — Science Learning Hub

A method of determining the age of a fossil by comparing its placement with that of fossils in other layers of rock. Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age. 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 which provided a means of absolute dating in the early 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques to determine the geological events. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occur, it remains a useful technique especially in materials lacking radioactive isotopes. Relative dating by biostratigraphy is the preferred method in paleontology, and is in some respects more accurate. The Law of Superposition was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century.

Relative dating

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.
