Variations in arid vs. wet climates reflected in land-based flora (e.g., palynomorphs) or lacustrine fauna (e.g., ostracodes) help identify climatic changes that control the development of stratigraphic sequences. | | * '''Climatic cycles'''—fluctuations of warm- and cold-water indicators in marine environments [e.g., calcareous nannofossils<ref name=ch17r78>Shaffer, B., L., 1987, The potential of calcareous nannofossils for recognizing Plio–Pleistocene climatic cycles and sequence boundaries on the shelf, in Innovative Biostratigraphic Approaches To Sequence Analysis: New Exploration Opportunities: Selected Papers and Illustrated Abstracts of the Eighth Annual Research conference of the Gulf Coast Section of the Society of Economic Paleontologists and Mineralogists Foundation, p. 142–145.</ref> or planktonic foraminifera<ref name=ch17r63>Martin, R., E., Neff, E., D., Johnson, G., W., Krantz, D., E., 1993, Biostratigraphic expression of Pleistocene sequence boundaries, Gulf of Mexico: Palaios, vol. 8, no. 2, p. 155–171., 10., 2307/3515169</ref>] may reflect sea level changes during periods of glacio-eustasy.
