Summary Unlike other free-living foraminifera some specimens of Flabellina cf angulosa d'Orbigny from various zones of the Upper Chalk show a strong tendency to have adherent end chambers. This together with a change of ornament from smooth to a pustulose shell seems to be unique amongst foraminifera.

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 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 ...

The spirotheca of the foraminifer Quasifusulina
Lethaia, 1993A 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.

Why are Foraminiferida Foraminifers ?
1990Fossil benthic and planktonic foraminifers play a major role in paleontology, first of all as a stratigraphic tool, but also in paleoecology, paleoclimatology, paleoceanography and paleobiogeography. Recent foraminifers are abundant and diverse in nearly all modern marine ecosystems, and although little is known about their life as organisms, they are ...

2023This thesis builds on the project GAČR 23-05217S, prof. RNDr. Katarína Holcová, Ph.D.,The Fossil seagrass meadows- the neglected Phanerozoic ecosystem: its contribution to the shelf biodiversity and identification in the fossil record. This work consists of two parts, the compilation and the practical part.
