This process is known as biostratigraphy / biostratigraphic correlation.
metabolic pathways
In DNA some genes/sequences are found only once or at most a few copies. Other sequences are found in numerous, repeated sequences. So high copy is more than 1 copy.
In the study of sequences, given a number n, the position to term rule tells you how the nth term of the sequence is calculated.
The term you are looking for is "biostratigraphy." This process involves comparing the fossil assemblages in different rock sequences to establish correlations and determine the relative ages of the rocks. By analyzing the fossils found in these rock layers, geologists can create a chronological framework for different areas.
