An absolute dating technique is one that gives a specific date, or a date that is specific within a given margin of error. If an object can only be relatively dated, that it can only be dated by reference to other objects or strata. For instance, if a burial mound was cut through by a Roman road, you could say that the mound was the earlier feature but you could not say how much earlier than the road it was.. Absolute dating would be if you had something like carbon 14 from the object tested and it gave a direct date.

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. The regular order of the occurrence of fossils in rock layers was discovered around by William Smith. While digging the Somerset Coal Canal in southwest England, he found that fossils were always in the same order in the rock layers.
