planktonic biostratigraphy

Planktonic biostratigraphy is a scientific method used to date and correlate layers of sedimentary rocks by examining tiny marine organisms, such as plankton, which lived in the ocean. These microscopic creatures, including foraminifera and coccolithophores, have distinct fossil forms that vary over time. By identifying and analyzing these fossils in rock layers, scientists can piece together a timeline of geological history, helping to understand past climates, environments, and the evolution of life. This technique is particularly valuable in oil exploration and studying ancient oceanic conditions.
