What is biozones?

Biozones are intervals of geological time in which certain types of fossil organisms are prevalent and can be used to identify and correlate rocks across different locations. These intervals are defined based on characteristic assemblages of fossil species, and can range in duration from years to millions of years. Biozones are important for understanding the evolution of life on Earth, as well as for reconstructing the ancient environments in which these organisms lived. They are also useful for geologists in identifying and correlating different rock formations, which can aid in the exploration and development of mineral and hydrocarbon resources. Biozones can be defined at various levels of biological organization, including species, genera, families, and orders, depending on the depth and resolution of the fossil record.
