Biostratigraphy is a branch of stratigraphy that uses the distribution of fossils to determine the relative ages of rocks and the geological history of an area. It is based on the principle that fossil organisms succeed one another in a definite and determinable order, and therefore that any time period can be recognized and identified by its fossil content. This method is particularly useful in areas where the rocks are not well-preserved or where the absolute dating methods are not applicable.
Biostratigraphy can be applied to various scales, from local to global. Local biostratigraphy involves the study
The process of biostratigraphic analysis involves identifying and cataloging the fossils present in a rock unit,
Biostratigraphy is a powerful tool in geology, providing valuable information about the history of life on
