bioestratigráficos

Bioestratigráficos refers to the field of biostratigraphy, a branch of stratigraphy that uses the fossil content of rock layers to establish their relative geological ages. This method relies on the principle of faunal succession, which states that fossil organisms succeed each other in a definite and determinable order, and therefore any given time interval in the Earth's history is characterized by a unique assemblage of fossils. Bioestratigraphy is crucial for correlating rock layers across different geographic locations, even when they are not physically continuous. By identifying index fossils, which are fossils of organisms that lived for a relatively short period of geological time but were widespread, geologists can determine the age of rock strata and understand the sequence of past life and geological events. The study involves detailed examination and comparison of fossil assemblages found in sedimentary rocks. These fossil groups, known as biozones, represent specific intervals of geological time and are used as markers for dating and correlation. Bioestratigráficos principles are fundamental to understanding Earth's history, from the evolution of life to the formation of geological structures.
