The study of microfossils is called [[micropaleontology]]. In micropaleontology, what would otherwise be distinct categories are grouped together based solely on their size, including microscopic organisms and minute parts of larger organisms. Numerous sediments have microfossils, which serve as significant [[biostratigraphic]], [[paleoenvironmental]], and paleoceanographic markers.<ref>{{cite book | last1=Armstrong | first1=Howard | last2=Brasier | first2=Martin | title=Microfossils | publication-place=New York, NY | date=2013 | isbn=978-1-118-68545-7 | oclc=904814387 | url=https://books.google.com/books?id=ULlUKMwizsAC&q=Microfossils}}</ref> Their widespread presence around the world and physical toughness makes microfossils important for biostratigraphy, while the manner in which they have reacted to environmental changes makes them helpful when reconstructing past environments.<ref>{{cite book | last=Martin | first=Ronald E. | title=Environmental Micropaleontology : the Application of Microfossils to Environmental Geology | publication-place=New York | date=2000 | isbn=978-1-4615-4167-7 | oclc=840285428 | url=https://books.google.com/books?id=QKbKBgAAQBAJ&q=Microfossils}}</ref>
