Micropaleontology (2004) 50 (Suppl_1): 93-106.
...K.J. Sebastian Meier; Christine Höll; Helmut Willems Abstract Modern and Late Quaternary oceanic assemblages of calcareous dinoflagellate cysts are often dominated by the species Calciodinellum albatrosianum , Leonella granifera and Pernambugia tuberosa . Their distribution in surface sediments...

... but the assemblage is much more diverse and reflects unstable more neritic conditions ( Bicarinellum tricarinelloides ), fluvial influence ( Leonella granifera ) and varying, temporally increased salinities ( Pernambugia tuberosa ), probably related to the increasingly restricted environment. The basal Pliocene...

... species ( S. albatrosiana , S. arctica , and S. tuberosa ) have revealed a tangential orientation of the crystallographic c-axes for S. albatrosiana , an oblique orientation for S. tuberosa , and a radial orientation for S. arctica ( Janofske, 1996, and unpublished observations). This led Janofske...
