microfossil
This term is used primarily within the specialized registers of micropaleontology and geology. It refers to biological remains—such as pollen, spores, or foraminifera—that require magnification for identification. Because these remains are often found in vast quantities within a single sediment sample, the term carries a connotation of statistical data and stratigraphic precision.
In a professional context, the word is used to describe markers for biostratigraphy, allowing scientists to date rock layers with high accuracy. It is distinct from macrofossils, which are visible to the naked eye, and is almost exclusively employed in scientific literature or academic discourse rather than casual conversation.
