(fō-ram'i-nif'ĕr-ă, for'ă-mi-nif'er-ă),
A subclass of Rhizopoda possessing anastomosing pseudopodia; these form a network around the cell that usually develops into a complex calcareous shell; an important component of the ocean bottom and of rockbeds overlying oil deposits.
[L. foramen, aperture, + fero, to carry]

Foraminifera

amoeboid PROTOZOANS that possess chitinous, calcareous or siliceous shells that are usually many-chambered. Calcareous Foraminifera are the main constituent of chalk.

(2001), although the maximum established using nannoplankton occurred a little earlier than the maximum established on the basis of planktonic foraminiferans. Similarly, the maximum estimated from planktonic foraminiferans in the Klyuchi 1 section occurs somewhat later than the maximum established on the basis of the nannoplankton.

The initial objective of this work was to study the newly exposed upper section of the road at the Djega outcrop using foraminiferans and palynomorphs and compare the age with that of the lower strata previously dated by Njoh [7], Njoh and Petters [8], and Njoh et al.
Bernhard focuses on protists called foraminiferans and symbiotic bacteria that seem to help the protists live in extreme environments such as the deep sea.
Nestor (1994) has provided 7-grade estimations of the plankton/benthos ratio in acid-resistant microfossil assemblages (mainly chitinozoans representing the plankton, and scolecodonts, melanoscleritoids, and foraminiferans representing the benthos).
Marsh foraminiferans, microfossils sensitive to various environmental stresses, can indicate oil pollution and are useful to monitor bioremediation.
Smaller lobsters relied to a greater extent than larger lobsters on soft or easily acquired food items (flesh, sessile juvenile bivalves, macroalgae, meiobenthic crustaceans, and foraminiferans).
