... micrographs varied. Three possible views were expressed: (1) Orbulinoides with some degenerate features; (2) planktic foraminifer; (3) benthic foraminifer related to Tretomphalus . We differ from the view that it is a benthic foraminifer and likely related to Tretomphalus . The chambers...

.... The Glabratellidae, originally placed in the Discorbacea, is herein transferred to the Orbitoidacea, the bilamellid nature determined by Reiss (1963, p. 66). Some genera placed by us (1964) in the Discorbidae, Rosalina, Tretomphalus, Earlmyersia and Heminwayina [=EoeponidellaJ, were shown to be bilamellid...

... samples. Meroplanktic species such as Tretomphalus bulloides (d'Orbigny) were very frequent in some PF samples. This group of foraminifers has both a benthic and a planktic stage in their life cycle ( Sliter, 1965 ; Rückert-Hilbig, 1983 ). The number of meroplanktics was recorded, but not further...
