      We compiled Ypresian benthic foraminiferal data from 17 middle bathyal-lower abyssal ocean drilling sites in the Pacific, Atlantic and Indian Oceans, in order to characterise early Eocene deep-sea faunas by comparing assemblages across space, paleodepth and time. The DWAF record from ODP Hole A in the Labrador Sea was re-studied and abundances were recalculated by excluding calcareous benthic foraminifera. This hole is a key locality, as it provides direct calibration of the DWAF biostratigraphy to the standard chronostratigraphy.

    Mimi Katz. My area of expertise is in paleoceanography and micropaleontology. Much of my work utilizes assemblage and geochemistry changes in the marine microfossil group benthic foraminifera, integrated with biostratigraphy, lithology, geophysical well logging, and seismic profile studies. In the late Paleocene to early Eocene, deep sea benthic foraminifera suffered their onlyglobal extinction of the last 75 million years and diversity decreased worldwide by % in a few thousand years.

A complete succession of lower bathyal–upper abyssal sediments was deposited across the Paleocene– Eocene Thermal Maximum (PETM) at Alamedilla (Betic Cordillera, Southern Spain), where the benthic foraminiferal turnover and extinction event associated with the negative carbon isotope excursion (CIE) across the PETM have been investigated.

Benthic foraminiferal abundance changes began at about Ma at Pacific Deep Sea Drilling Project (DSDP) Site The Paleocene-Eocene boundary itself is marked by a prominent extinction among deep-sea foraminifera (Thomas, ), associated with a pronounced surface warming characterized by a global mean temperature increase of about 5 °C (Dunkley Jones et al., )—known as the Paleocene-Eocene Thermal Maximum (“PETM”) (Zachos et al., ).

The Paleocene–Eocene Thermal Maximum (PETM), alternatively "Eocene thermal maximum 1" (ETM1), and formerly known as the "Initial Eocene" or "Late Paleocene Thermal Maximum", was a time period with a more than 5–8 °C global average temperature rise across the event.

This climate event occurred at the time boundary of the Paleocene and Eocene geological epochs. During the Late Paleocene Thermal Maximum (LPTM) benthic foraminifera at middle bathyal and greater depths suffered extinction of % of species during a few thousand years.

The response of benthic foraminifera to the Cretaceous/Paleogene (K/Pg) impact event is key to reconstruct paleoenvironmental changes and the specific mechanisms triggering faunal turnover in the marine realm, especially because this group did not suffer significant extinction (thus shows a continuous record across the boundary), and because its faunal turnover shows paleobiogeographic.

A zonal scheme for the Lower Paleogene of the northern Pacific Ocean is proposed on the basis of the stratigraphic distribution of benthic foraminifers in the lower bathyal–abyssal beds studied in boreholes in the North and South Pacific regions.

This scheme includes eight subdivisions (six zones and two subzones). The boundaries of the benthic zonal subdivisions are defined by bioevents. Paleocene–Eocene Bathyal and Abyssal Benthic Foraminifera from the Atlantic Ocean. Micropaleontology, Spec.

Based on the stratigraphic distribution of benthic foraminifera in the lower bathyal–abyssal sediments uncovered by boreholes drilled under the framework of the Deep Sea Drilling Project (DSDP) and Ocean Drilling Project (ODP) in the Northern and Southern Pacific, the Lower Paleogene biostratigraphic zonal scale based on deep-water benthic foraminifera is proposed.
