In terms of biostratigraphy, foraminifera have become extremely useful, different forms have shown evolutionary bursts at different periods and generally if one form is not available to be utilised for biostratigraphy another is. 2014-06-16 2017-04-07 Foraminifera, or forams for short, have amoeba-like bodies within tests that are generally made of calcium carbonate. They have one or more openings through which the foram can extend its body by means of thin, threadlike projections called pseudopods. Pseudopods are used for functions such as food capture and moving around.

They are both numerous and taxonomically diverse in assemblages throughout the Mesozoic and Cenozoic and have been used extensively in the oil industry since Józef Gryzbowski Paleoecology of Cretaceous Foraminifera: Examples from the Atlantic Ocean and Gulf of Mexico Region deep sea, and led to a wider appreciation of the ecology of the group. For example palaeobathymetry, where assemblage composition is used and palaeotemperature where isotope analysis of foraminifera tests is a standard procedure. In terms of biostratigraphy, foraminifera have become extremely useful, different forms have shown evolutionary bursts at different periods and generally if one form is not available to be utilised for biostratigraphy another is.

A short summary of this paper.

One approach to modelling the morphology of foraminifera shells [Tyszka and Topa, Paleobiology 31(3), 522 (2005)] in two dimensions treats the chambers as overlapping circles. On a larger scale, symmetry is a feature of the overall body plans of many organisms, from microscopic foraminifera to large vertebrates.

Se hela listan på mccrone.com In places, foraminifera are so abundant that the sediment on the bottom is mostly made up of their shells. For example, the pink sands of Bermuda get their color from the shells of a foraminiferan called Homotrema rubrum which has pink to red-colored shells. Benthic foraminifera include two major types of foraminifera.

Bowser †Department of Zoology and Animal Biology, University of Geneva, Sciences III, 1211 Geneva 4, Switzerland; §Southampton Oceanography Centre, Empress Dock, European Way, Southampton SO14 3ZH, United Kingdom Foraminifera are themselves eaten by a host of larger organisms, including invertebrates, fish, shorebirds, and other foraminifera. It has been suggested, however, that in some cases predators may be more interested in the calcium from foram shells than in the organisms themselves.
