In essence, paleontologic analysis is based on knowing the distribution of fossil species in time and space. All fossil species persisted for a limited geologic duration and were restricted in habitat to specific [[Paleoenvironmental analysis|paleoenvironments]] characterized by a range of ecological parameters such as temperature, salinity, dissolved oxygen, and food availability. Because several important parameters vary somewhat systematically with water depth in marine environments, benthic fossils (remains of bottom-dwelling organisms) commonly are used to estimate [[paleobathymetry]] for basin modeling and [[sequence stratigraphy]].
