Benthic foraminifera include two major types of foraminifera. The small benthic foraminifera, which have simple internal structures, and the larger benthic foraminifera, which have complicated internal structures and occur abundantly in the shelf regions of most tropical and subtropical shallow marine, carbonate-rich environments (Boudagher-Fadel and Price, 2013).

Although there has been an implicit assumption that the species-specific depth habitats of fossil planktonic foraminifera were invariant through time, planktonic paleoecology is a potential variable. A reduction in dissolved oxygen availability in marine habitats is among the predicted consequences of increasing global temperatures. An understanding of past oxygenation is critical for predictions of future changes in the extent and distribution of oxygen minimum zones (OMZs). Benthic foraminifera have been used to assess changes in paleo-oxygenation, and according to prevailing thought 2017-02-01 Benthic foraminifera can live in a wide variety of habitats all over the world. They must live in the substrate, but they can tolerate various salinities (from brackish salt marshes to open ocean). Different species assemblages occur with varying environmental parameters.

Several studies showed that the depth habitat of planktonic foraminifera varies throughout the year in response to changing environmental conditions. Rebotim et al. identified an annual cycle in the habitat of T. sacculifer and N. incompta in the subtropical eastern North Atlantic. Habitat preference of ostracods and foraminifera The high abundance of the foraminifera Ammonia parkinsoniana , A. tepida and Elphidium hispidulum in Tanjung Adang Shoal, Merambong Shoal and around Merambong Island reflects a brackish environment (Debenay et al ., Reference Debenay, Beneteau, Zhang, Geslin, Redois and Fernandez-gonzalez 1998 ). Modern benthic foraminifera are distributed according to parameters of their preferred habitat. Often these parameters are correlated with ocean depth.

The carbon stable isotope (13 C) composition of the calcitic tests of planktonic foraminifera has an important role as a geochemical tracer of ocean carbon system changes associated with the Cretaceous/Paleogene (K/Pg) mass extinction event and its aftermath.Questions remain, however, about the extent of 13 C isotopic disequilibrium effects and the impact of depth habitat evolution on test

Based on sedimentary evidence and the micro- and macrofauna at this site, we infer that the 9-m-thick sequence was deposited at a paleodepth of 70–150 m. Taxa present throughout the sequence include a diverse assemblage of ammonites, bivalves, and gastropods, abundant benthic foraminifera, and rare planktonic foraminifera.
