Resumen de Scanning Electron Microscopy of Wall Structures in Some Benthonic and Planktonic Foraminiferida
Representatives of the genera Bulimina, Globobulimina, Turrilina, Cassidulina, Nonion, and Asterigerina considered earlier as being «monolamellar» are shown in the scanning electron microscope to be «bilamellar». In contrast with some recently published views, all planktonic foraminiferida possess a distinct bilamellar test construction pattern.
