...MICHAEL KNAPPERTSBUSCH Abstract A detailed investigation of the morphological evolution of the coccolithophorids Calcidiscus leptoporus and C. macintyrei from the Early Miocene to the Quaternary shows that microevolutionary patterns were very complex. Speciation patterns such as cladogenesis...

... changes. We found a strong seasonality in coccolithophore fluxes corresponding to the seasonal monsoonal development. Several species showed specific annual trends, however, the annual cycles of the majority of living species are not preserved and only a smoothed signal with gradual intraannual changes...

... conditions, could not tolerate anoxia. Here we present evidence that fossil foraminifera were able to successfully colonize anoxic–dysoxic bottom waters, by using adaptations similar to those found in living species. Our study is based on a multi proxy micropaleontological and geochemical investigation...

... coccoliths – the skeletal remains of planktonic algae called coccolithophorids. Coccoliths are circular or elliptical calcite platelets with a size range of 2–10 μm. Each coccolith is composed of a number of calcite crystals, the number and size of which may vary significantly according to genus. During...

Only his late nineteenth-century work dealt with pollen. He studied thoroughly the pollen of about 2,200 plant species, a much more...

... coccolithophorid (calcifying) or non-calcifying haptophytes are known to produce alkenones. The cosmopolitan species E. huxleyi is abundant and geographically widespread in the modern ocean, tolerating a wide range of temperatures, salinities, nutrient availability and light levels and sometimes composing 60...

Reworked taxa – several nannofossil species found in the NP14 and NP15 zones are typical for the Paleocene ( Romein, 1979 ; Perch-Nielsen, 1985 ). These species belong to Ellipsolithus...

The data of Norris & Wilson (1998) , although still to be tested in other localities, suggest that the relationship between morphology and habitat depth is not straightforward.
