An ontogenetic description of Orbulina suturalis (Foraminifera) from the Danube Basin (Slovakia)
Original language description
Orbulina suturalis (Brönnimann, 1951) is a planktic foraminifera species that occurred in the Central Paratethys during the Middle Miocene, throughout the Badenian (Langhian, Serravallian) stage. Despite the stratigraphic and paleoecologic significance, the ontogeny of the species remained seldom explored. In this study the inner shell morphology was observed by using a tomographic microscope to identify the ontogenetic stages. The entire shell development of Orbulina suturalis, from the monothalamous prolocular stage to the polythalamous terminal stage, was interpreted. Each stage is described by its general morphological features, such as the dimensions of the shell, the shape and number of the chambers, the position of the aperture, the peripheral outline, the texture of the wall and the coiling direction. The constructed ontogenetic model of Orbulina suturalis was correlated with the "five stage concept" of Trilobatus sacculifer introduced by Brummer et al. (1987).
