Chronostratigraphy

Chronostratigraphy is a branch of geology that studies the age and timing of rock layers (strata) in the Earth’s crust. It helps scientists understand the sequence of geological events and how different layers relate to one another through time. By analyzing these layers, researchers can determine the relative ages of rock formations, which is essential for dating fossils and understanding Earth’s history. Essentially, chronostratigraphy provides a framework for mapping out the geological timeline, allowing us to piece together the story of our planet.
