This research used samples provided by the Ocean Drilling Program (ODP). The ODP is funded by the U.S. National Science Foundation (NSF) and participating countries under management of the Joint Oceanographic Institutions (JOI), Inc. Funding for ODP participation was provided by the Natural Environment Research Council (NERC), United Kingdom. The author would also like to acknowledge the contributions made by the other ODP Leg 198 shipboard palaeontologists, namely, Mark Leckie, Maria Rose Petrizzo, Jason Eleson, Isabella Premoli Silva, Tim Bralower, and Kotaro Takeda, and the science party in general, who made the leg so productive and enjoyable. The manuscript was greatly aided by the ODP editors and reviews by Jörg Mutterlose and Elisabetta Erba.
