“…Eighty-nine samples are described in Appendix 1* and the age-important planktonic foraminifera found in these are listed in Appendix 2*. Age determinations (Appendix 1*) are based on planktonic foraminiferal zones and datum levels outlined by Caron (1985), BouDagher-Fadel et al (1997), Petrizzo (2000), Howe et al (2003) and Campbell et al (2004) for the Cretaceous; Tourmakine and Luterbacher (1985) and Berggren and Pearson (2005: P zonation for Paleocene, E zonation for Eocene) for the Paleogene; and Blow (1969: N zonation), Kennett and Srinivasan (1983: revised N zonation) and Berggren et al (1995a, b) for the Neogene. The T-Letter Stages, based on larger benthic foraminifera, follow Adams (1970Adams ( , 1984.…”

Marine mudstone sediments recovered from multiple boreholes drilled in southeast Tanzania yield some of the best preserved Turonian microfossils in the world, and these specimens provide a valuable new perspective on planktonic foraminiferal and calcareous nannofossil evolution, taxonomy, biostratigraphy, and biodiversity. High sedimentation rates and the consistent presence of well-preserved microfossil assemblages throughout the sequence increase the resolution of biostratigraphic data generated allowing for improved correlation within and outside the depositional basin. The late early-middle Turonian Tanzanian record reveals prolonged species stasis with essentially no changes in relative abundance, no extinctions, and no evolutionary appearances for both calcareous plankton groups until the late middle Turonian. This interval is followed in the late Turonian by two species turnovers. The older of these occurs at the top of the mid-Turonian Helvetoglobotruncana helvetica Zone, where last occurrences of three planktonic foraminiferal species are followed, within several meters, by first occurrences of five foraminiferal species and an increase in the abundance of dwarfed planktonic forms. Changes in the calcareous nannofossil assemblages at this level are modest and include the extinction of one calcareous nannofossil species and an abrupt but temporary spike in the abundance of another species. There are no obvious changes in lithology, bulk sediment geochemistry, or stable isotope values across this first turnover event. The second, larger species turnover occurs at a hiatus within the late Turonian Marginotruncana sinuosa-Huberella huberi Zone and is marked by extinction of three calcareous nannofossil species followed by first appearances of four calcareous nannofossil species. Corresponding with the nannofossil first occurrences is a dramatic increase in the relative abundance of several species of biserial planktonic foraminifera, an increase in average grain size, and a shift in preservation

“…It is characteristic of the Upper Cretaceous of north-west Europe (H akansson et al, 1974) but occurs in many stratigraphic intervals and regions including the American continent (e.g. Bottjer, 1981;Bottjer 1986), North Africa (Ghorab, 1961;Holail & Lohmann, 1994) and Australia (Campbell et al, 2004). The north-west European Upper Cretaceous chalk was deposited in the Cenomanian-Maastrichtian, an interval characterized by greenhouse climate and one of the highest sealevels in the Phanerozoic (Haq et al, 1987;Surlyk et al, 2003).…”

Detailed facies analysis of a 350 m long core of upper Campanian–Maastrichtian chalk at Stevns Peninsula, eastern Denmark, shows that four mudstone and wackestone chalk facies account for close to 95% of the succession, and that bioturbated mudstone chalk alone accounts for nearly 55% of the sediment. Sedimentation took place in deep water, below the photic zone and storm‐wave base, and is characterized by decimetre to metre‐scale variations in facies and trace fossil assemblages indicating repeated shifts in depositional environment. Integration of facies with published data on sea‐surface temperature and accumulation rates suggests that sea‐surface temperature is the most important parameter in controlling stratification of the water column and thereby, indirectly, the observed variations in depositional facies. However, bioturbated mudstone chalk occurs in all stratigraphic levels independent of accumulation rates and sea temperatures and is interpreted to represent a very broad set of deep water environmental conditions with an ample supply of calcareous nannofossil debris and intense bioturbation. Longer term shifts in deposition are best expressed by distribution of clay, flint and bioturbated micro‐wackestone, bioturbated wackestone and laminated mudstone chalk facies, whereas the trace fossil assemblages appear less useful. The data set indicates overall shallowing over time with two distinctive events of clay influx to the basin during the late Campanian–earliest Maastrichtian and late Maastrichtian.
