The Unitary Association method in biochronology and its potential stratigraphic power between benthic and planktic organisms: A case study on foraminifers from Paleocene–Eocene strata of southern Egypt

Geobios, 2018
Although foraminifers have been extensively used for biochronology, no quantitative evaluation of the quality of their application is available. In this work we apply a quantitative approach – the Unitary Association (UA) method – to evaluate the ...

Foraminifers (Planktonic)

2015
Benthic foraminifera are unicellular, aquatic (marine and brackish) eukaryotic organisms. They are benthic bottom dwellers characterized by high diversity and abundance. In benthic foraminifera, the cytoplasmic body is encased in organic or mineralized test (shell), which provides a fossil record (Cambrian to recent).

The spirotheca of the foraminifer Quasifusulina

Lethaia, 1993
A SEM study on the test wall of Quasifusulina has demonstrated that the ultrastructures in the spirotheca Quasifusulina different from those of related fusulinid genera, such as Fusulinella and Triticites. The primary wall structure is prokerotheca rather than diaphanotheca or keriotheca, as previously described.

Foraminifers and Continental Drift

AAPG Bulletin, 1974
Abstract The global distribution of Orbitolina along the tropical and subtropical belts of the world during the Early Cretaceous is interpreted as an ecological chance caused by absence of competition. Distribution and diversification of Late Cretaceous larger foraminifers in the Caribbean appear more closely related to ecology than ...

FORAMINIFERS AS HARD SUBSTRATES: AN EXAMPLE FROM THE WASHINGTON (USA) CONTINENTAL SHELF OF SMALLER FORAMINIFERS ATTACHED TO LARGER, AGGLUTINATE FORAMINIFERS

The Journal of Foraminiferal Research, 2008
This study from the continental shelf offshore from Washington, USA, describes an occurrence of attached foraminifers using other, larger foraminifers as their hard substrate. Isolated instances of such associations have been illustrated in a few publications; however, the example documented here is of an extensive relationship between smaller attached

The Living Foraminifer

1981
The micropalaeontologist is concerned with the abandoned, dead shells of Foraminifera and classification of fossil species proceeds entirely upon the basis of the morphology of the hard parts or test. However, he requires a knowledge of the live animal because the morphology and the evolutionary changes so important in stratigraphy can only be ...
