...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...
