Sequence stratigraphy is particularly useful at constraining shoreline regression and transgression trends by identifying stacking patterns limited by stratigraphic surfaces. These tests (shells), which are typically small (10-100 microns across), include diatoms and radiolarians, foraminifera and coccolithophores. Marine sediments are typically broken down into two major categories: Biogenic oozes (yes, ooze is a technical term!) Precambrian fossils of fungi are sparse, and the knowledge of their early evolution and the role they played in the colonization of land surface are limited. Many extinct organisms have been identified from microfossils, so this helps us to reconstruct the evolutionary record. Each shell has one or more chambers in which the protoplasm of the living protist resided. Prokaryotes have their DNA loosely organized within the cell and not in the cell nucleus, and chromosomes are absent. 7, p. 167-199.
