Figure F7. Stratigraphic summary for 65–40 Ma. Biostratigraphy after Bralower, Premoli Silva, Malone, et al. (2002), Bralower (this volume), Petrizzo et al. (this volume), and Premoli Silva et al. (this volume). The Paleocene/Eocene boundary was set at 55 Ma (see discussion in Aubry and Ouda, 2003). Condensed pattern annotates intervals in which some biozones could not be identified with certainty and/or may comprise short hiatuses or unconformities. OAE = Ocean Anoxic Event, TD = total depth.
