The thick-lenticular Nummulites venosus (Fichtel and Moll) and the spherical Baculogypsinoides spinosus Yabe and Hanzawa, both living in deeper regions, are transported less often, while Cycloclypeus carpenteri Brady, with a similar depth distribution, shows a high degree...

In addition, gamete flagella of Operculina cf. complanata have mastigonemes, a feature previously reported in only two foraminifera: the “lower” allogromiid Boderia turneri and the “higher...

...Johann Hohenegger; Antonino Briguglio Abstract The “critical shear velocity” and “settling velocity” of foraminiferal shells are important parameters for determining hydrodynamic conditions during deposition of Nummulites banks. These can be estimated by determining the size, shape, and density...
