Definition
Biostratigraphy is the branch of geology that uses fossilized remains of organisms to establish the relative ages of rock layers and correlate them across different geographic locations. Fossil correlation involves matching and comparing fossil assemblages from various strata to infer chronological relationships and environmental conditions in Earth's history.
Summary
Biostratigraphy is a vital field in geology that uses fossils to date and correlate rock layers, providing insights into Earth's history and the evolution of life. By studying the fossil content of different strata, geologists can establish a timeline of geological events and understand the distribution of various species over time. Fossil correlation is essential for practical applications, such as oil exploration and environmental assessments. Understanding biostratigraphy not only helps in resource management but also enhances our knowledge of past climates and ecosystems, making it a crucial area of study for both scientists and industry professionals.
