Biostratigraphic Analysis

Biostratigraphic analysis is a method used by geologists to date and organize layers of rock by examining the fossils within them. Since certain fossils, called index fossils, lived during specific time periods, their presence helps determine the age of the surrounding rocks. This approach allows scientists to piece together the Earth's history, understand past environments, and correlate rock layers across different locations. It is a crucial tool for reconstructing the chronological sequence of geological events and understanding the evolution of life on Earth.
