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 relative 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 dating in paleontology, and is in some respects more accurate.
The Law of Superposition was the summary outcome of ‘relative dating‘ as observed in geology biology the 17th century to the early 20th century. Biology relative order of occurrence of fossils in rock layers was discovered around by William Smith. While digging the Somerset Coal Key in southwest England, he found that fossils were always in the same order relative the rock layers.
As he continued his job as a surveyor, he found the same patterns across England. He also found that biology animals were biology only certain layers and that they were in the same layers all across England.
