Taxonomy and nomenclature are not pursued for their own sake but whenever it becomes necessary to clear up taxonomic and/or nomenclatural problems. This work is the basis of reliable data sets for the solutions of major questions, i.e. correct interpretations of global change, paleoclimate, paleoecology, and global correlations.
