Foraminifers and Continental Drift
AAPG Bulletin, 1974Abstract 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 ...

Evolution of early planktic foraminifers
Marine Micropaleontology, 1983Abstract The evolution of Mesozoic species of planktic foraminifers, particularly the succession of their morphotypes and the variation in their diversity and their abundance, is shown to be related to the adaptation of evolutionary strategy to fluctuations in the oceanic environment. During periods of stress (“oligotaxic period”) the more primitive

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

Pyritization in living foraminifers
The Journal of Foraminiferal Research, 1973Pyrite found in tests of living specimens (formed by bacteria in test), may indicate disease or a relationship between foraminifera and bacteria, specimens from Puerto ...

The accuracy of δ11B measurements of foraminifers
Chemical Geology, 2010Abstract Values of δ11B reported in the literature for Holocene samples of the same foraminiferal species show large variability (6‰) relative to cited precision (

Paleobiology, 2015
Abstract Evolution of photosymbiotic ecology is an important adaptation for planktic foraminifers that enhances the ecological advantage of living in oligotrophic oceans. Therefore, detecting photosymbiotic ecology in fossil species is one of the keys to understanding the paleobiodiversity dynamics of planktic ...

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 ...

The foraminifer genera Monotaxinoides and Eolasiodiscus
International Geology Review, 1965The genera Monotaxinoides Brazhnikova and Yartseva and Eolasiodiscus Reytlinger were both established at the same time for small Late Carboniferous Foraminifera probably derived from the genus Howc...
