Origin of the foraminifera. [PDF]
We report nuclear small-subunit rDNA sequences for two species of the benthic foraminifer Ammonia. Because of their abundance in present and past seas, the foraminifera are a very important group of organisms used in a wide range of geologic studies; however, the ancestry of this group was, until now, unknown.

Impact of carbonate saturation on large Caribbean benthic foraminifera assemblages [PDF]
Increasing atmospheric carbon dioxide and its dissolution in seawater have reduced ocean pH and carbonate ion concentrations, with potential implications on calcifying organisms.

Foraminifera are shelled single-celled protists that are found in all marine environments. Benthic foraminifera either live in sediments or attach to surfaces on the seafloor. Understanding the distribution and ecological response of benthic foraminifera

Planktonic foraminifera are key to understanding paleoclimate and plankton evolution, but their origins are unclear. Here, the authors use a molecular clock to suggest that benthic foraminifera dispersed in plankton and renew planktonic foraminifera ...

Foraminifera associated with cold seeps in marine sediments
Cold seep foraminifera have attracted considerable attention as they provide valuable insights into the study of cold seeps. This study provides a comprehensive overview of the manifestations of foraminifera in cold seep environments and methane seepage ...

The evolution of early Foraminifera [PDF]
Fossil Foraminifera appear in the Early Cambrian, at about the same time as the first skeletonized metazoans. However, due to the inadequate preservation of early unilocular (single-chambered) foraminiferal tests and difficulties in their identification, the evolution of early foraminifers is poorly understood. By using molecular data from a wide range

Biomineralization in perforate foraminifera [PDF]
In this paper, we review the current understanding of biomineralization in perforate foraminifera. Ideas on the mechanisms responsible for the flux of Ca2 + and inorganic carbon from seawater into the test were originally based on light and electron microscopic observations of calcifying foraminifera.

Eocene foraminiferal biofacies in Kutch Basin (India) in context of palaeoclimate and palaeoecology
The Eocene Epoch passed through multiple hyperthermal events and recorded highest temperatures in the Cenozoic. Very few studies from Eocene palaeotropical sites have recorded changes in shallow marine foraminiferal assemblages.
