KurzbeschreibungGeneral introduction to the various groups of microfossils, their morphology, taxonomy, biology, ecology, and application in such fields as biostratigraphy, palaeoecology, palaeoceanography, and the solution of other geological problems. Practical exercises and demonstrations of material will involve the examination of picked and strew-mounted microscope slides.
LernzielAt the end of the module you will be able to:
1. Assign a microfossil to its major taxonomic group (e.g. foraminifer, ostracod, dinoflagellate, palynomorph, etc.).
2. Be aware of, and to recognise, the main morphological and compositional features which allow assignation of an individual fossil to each group.
3. Draw basic stratigraphic conclusions about microfossil assemblages (e.g. age of rock unit, correlations, etc.)
4. Deduce paleoecological and/or paleoceanographic interpretations from different assemblages of microfossils.
5. Understand the applicability of particular microfossil groups to particular lithologies and particular geological time periods.
6. Determine which microfossil groups are most applicable to the solution of a variety of particular geological problems.
InhaltLectures will introduce the various microfossil groups and detail their utility as important indicators of past environments by examining the ecology of living microplankton taxa and extrapolating this to the fossil record (paleoecology, paleoceanography). The applicability of different microfossil groups in providing both relative timescales (through zonal schemes) and biostratigraphic correlation will be detailed, as will the role of certain microfossils in understanding evolutionary processes. Microplankton as agents of global environmental change will also be investigated, especially with regard to fluxes of CaCO3 and C and hence to CO2 in the atmosphere. The microfossil groups which will be studied in the above context are those which form mineralised skeletons (calcareous, siliceous, phosphatic) and the organic-walled microfossils (known as palynomorphs).
