Distribution of calcareous nannofossils in Cretaceous to Paleogene sediments of ODP Hole 208-1262C at Walvis Ridge, South Atlantic Ocean (Appendix A)

Site 1262 in the South Atlantic Ocean has provided a stratigraphically continuous deep Cretaceous/Paleogene boundary sequence. High resolution calcareous nannofossil quantitative analyses were carried out across the K/P boundary, and provided a remarkable record of the abrupt and catastrophic extinction. The calcareous nannofossil assemblages are abundant and well preserved allowing to obtain a precise bioevent sequence and to document in detail the survivors and victims and the subsequent recovery across the K/P boundary.
