Nannoplankton Stratigraphy

Nannoplankton stratigraphy is the study of tiny, single-celled marine organisms called nannoplankton and their fossilized remains in sediment layers. By analyzing changes in their types and abundance over time, scientists can precisely date and correlate different geological strata. This method helps reconstruct Earth's history, including climate shifts and events like mass extinctions, because nannoplankton evolved rapidly and responded to environmental changes, making them valuable markers for understanding the Earth's past in a detailed and organized way.
