Nannofossil Biostratigraphy

Nannofossil biostratigraphy is a scientific method that uses tiny fossilized remains of microscopic marine algae called nannofossils to date and correlate geological layers. Because different nannofossil species appeared and disappeared at specific times in Earth's history, their presence in sediment samples helps scientists determine the age of rocks and understand past environmental conditions. This technique is valuable in geology and paleontology for reconstructing Earth's history, exploring for oil and gas, and understanding climate change over millions of years.
