Microfossils are especially noteworthy for their importance in biostratigraphy.
It has uses in biostratigraphy; certain scratch patterns are unique to certain time intervals.
Biostratigraphy or paleontologic stratigraphy is based on fossil evidence in the rock layers.
The Quaternary subdivisions were defined based on biostratigraphy instead of paleoclimate.
