Evolution of early planktic foraminifers

Marine Micropaleontology, 1983
Abstract 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

Exploring photosymbiotic ecology of planktic foraminifers from chamber-by-chamber isotopic history of individual foraminifers

Paleobiology, 2015
AbstractEvolution 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 foraminifers.

Foraminifers and Continental Drift

AAPG Bulletin, 1974
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 to continental drift.

Pyritization in living foraminifers

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