New coccolithophorid taxa from Geulhemmerberg airshaft, Lower Paleocene, the Netherlands

摘要

A previous study on calcareous nannofossils of the K/T boundary section exposed in the Geulhemmergerg cave, The Netherlands, revealed two coccosphere-rich horizons with about 35 different coccolithophorid species. In the subsequent investigation Of an airshaft section above this interval, an additional horizon with numerous intact coccospheres was discovered. Among the 32 Coccolithophorid species from theis upper horizon, three are new: Cruciplacolithus filigranus n. sp., Prinsius scissuratus n. sp. and Prinsius simplex n. sp.
