Gametogenesis in Planktonic Foraminifera

Science, 1976
Gametogenesis in Globigerinella aequilateralis and Globigerinoides sacculifer in culture is preceded by sinking of the organism and loss of its spines. Hundreds of thousands of flagellated gametes, about 5 micrometers in diameter, are produced within the parent shell and released within a ...

Barium in planktonic foraminifera

Geochimica et Cosmochimica Acta, 1991
Abstract Reconstructions of Ba distributions in ancient oceanic surface waters could provide new insight into paleoceanographic change. Calcite shells of planktonic foraminifera potentially provide a means of reconstructing such paleo-Ba distributions if lattice-bound Ba can be determined on shells recovered from deep-sea cores.

Sedimentation of planktonic foraminifera

Marine Geology, 1971
Fossil assemblages of planktonic Foraminifera contain many valuable clues to paleoclimate and paleo-oceanography. Unfortunately, our understanding of production, dissolution, redeposition, and other processes of foraminiferal sedimentation is but rudimentary.

Biogeography of planktonic Foraminifera

1999
There are several important unresolved issues in the area of modern planktonic foraminiferal biogeography. The large-scale latitudinally symmetrical faunal provinces do not appear to show a consistent relationship to comparably-scaled hydrographic features.

Planktonic Foraminifera from the American Oligocene

Science, 1964
Planktonic foraminiferal assemblages from the Vicksburg group of the Gulf Coast region comprise species comparable with those found in the Oligocene of Tanganyika and northern Europe. The fauna is transitional between typical Upper Eocene and Miocene; its intermediate position is indicative of an Oligocene age.

Trophic activity of planktonic foraminifera

Journal of the Marine Biological Association of the United Kingdom, 1979
Few studies have been reported on the predatory habits of planktonic foraminifera or on their position in marine food webs. Planktonic foraminifera are large marine Sarcodina possessing a calcium carbonate shell (usually < 1 mm diam.) surrounded by a dense halo of rhizopodia that in some species may increase the cell diameter to 20 mm.

Biology of Planktonic Foraminifera

Notes for a Short Course: Studies in Geology, 1982
The history of investigations of planktonic foraminifera leading to their current, wide applications in biostratigraphic correlation of Mesozoic and Cenozoic marine sediments can be traced to the discovery by Owen (1867) of the floating habit of certain foraminifera, later confirmed by Brady (1884), and the recognition by Murray and Renard (1891) that ...
