" virtually all sedimentary systems have stratigraphic disorder at come scale is probably a common feature of the fossil record " Fossils out of Sequences Cutler Palaios June 1990 on The conclusion of some scientists is that the Law of Superposition just doesn't work Shindewolf Comments on Some Stratigraphic Terms American Journal of Science June 1957 " Historical geology relies chiefly on paleontology the study of fossil organisms. The Law of Superposition makes logical sense but in practice it is the nature of the fossils found in the sedimentary layers that determine the relative ages of the rocks.
The theory of descent with modification trumps the empirical evidence of superposition.

Current scientific evidence shows that the Earth is: c) more than 4 billion years old 2.
Contrary to this, absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.
The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other.
However the relative ages of rocks is more commonly determined by the presumed ages of the fossils found in the sedimentary layers.The law of superposition is based on the common sense argument that the bottom layer had to laid down first.The bottom layer because it logically had to be laid down first must be older.The age of the fossil will be an age range between the ages of the two volcanic layers. The diagram below shows a portion of the Geologic Time Scale. In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts.
Sometimes beds of rock can turn over the other way, so be very cautious when relatively dating rocks!
