“…The Palaeogene carbonate succession located in the Umbria -Marche (U -M) Basin in the northeastern Apennines of Italy is probably the most thoroughly studied in the Tethyan Realm, thanks to the accessibility of numerous well-exposed outcrops throughout this region, and its remarkable record of many crucial aspects of Earth's history from the Cretaceous -Palaeogene (K -Pg) boundary through to the uppermost Oligocene (Coccioni et al 1986(Coccioni et al , 1988(Coccioni et al , 1989(Coccioni et al , 2000(Coccioni et al , 2008(Coccioni et al , 2012Cresta et al 1989;Bellagamba & Coccioni 1990;Mattias et al 1992;Brinkhuis & Biffi 1993;Premoli Silva & Jenkins 1993;Lowrie & Lanci 1994;Montanari et al 1994Montanari et al , 1997Galeotti et al 2000Galeotti et al , 2004Galeotti et al , 2010Montanari & Koeberl 2000;Spezzaferri et al 2002;Coccioni & Galeotti 2003;Bodiselitsch et al 2004;Jovane et al 2004Jovane et al , 2006Jovane et al , 2007aJovane et al , b, 2009Jovane et al , 2010Brown et al 2009;Giusberti et al 2009;Hyland et al 2009;Pross et al 2010, and references therein).…”

Extensive outcrops in the Umbria Marche Basin of central Italy include some of the most complete successions of Palaeogene sediments known from the Tethyan Realm. Owing to the continuous deposition in a pelagic setting, a rather modest tectonic overprint, the availability of excellent age control through magneto-, bio-, chemo- and tephrostratigraphy, and direct radioisotopic dates from interbedded volcaniclastic layers, these sediments have played a prominent role in the establishment of standard Palaeogene time scales. We present here a complete and well-preserved Palaeogene pelagic composite succession of the Umbria-Marche Basin, which provides the means for an accurate and precise calibration of the Palaeogene time scale. As a necessary step towards the compilation of a more robust database on a wide scale so as to improve the magneto-, bio- and chronostratigraphic framework of the classical southern Tethyan zonations, enabling regional and supraregional correlations, we have constructed a record of reliable Palaeogene planktonic foraminifera, calcareous nannofossil and dinocyst biohorizons commonly used in tropical to subtropical Cenozoic zonations. In addition, an age model is provided for the Palaeogene pelagic composite succession based on magnetostratigraphy, planktonic foraminifera and calcareous nannofossils, which contributes to an integrated chronology for the Palaeogene Tethyan sediments from c. 65.5 to 23 Ma

Ecological Response of Shallow-Marine Foraminifera to Early Eocene Warming in Equatorial India

The Earth's climate was marked by a pronounced warming at the onset of the Eocene Epoch, followed by successive short-lived warmings in the later part of the early Eocene. The carbon isotope (d 13 C) excursions, the fingerprints of the Eocene hyperthermal events, have been established in the geological sections in India that lay across the equator in the early Eocene. The present study examines how shallowmarine foraminifera responded to the thermal events. The hyperthermal events, identified in sections of Kutch and Cambay basins corresponding to Shallow Benthic Zones (SBZs) between SBZ 5/6 to SBZ 11, have been examined for their foraminiferal assemblages, which indicate a shallowmarine environment. A significant change in the foraminiferal assemblage occurs from SBZ 5/6 to SBZ 11. The SBZ 5/6 to SBZ 10 interval (corresponding to Paleocene-Eocene Thermal Maximum, Eocene Thermal Maximum 2 and Eocene Thermal Maximum 3) is characterized by (i) low diversity and dwarfed foraminifera, (ii) rectilinear benthic foraminifera, and (iii) biserial and triserial planktic foraminifera that are known to survive in areas of high runoff, upwelling or otherwise eutrophic conditions. The stressed environments of the SBZ 5/6 to SBZ 10 appear to have ameliorated in SBZ 11 (corresponding to Early Eocene Climatic Optimum) with significant increase in abundance and diversity of foraminifera, dominance of K-strategists, and a switch from eutrophic to oligotrophic environments.

Late Paleocene‐middle Eocene benthic foraminifera on a Pacific seamount (Allison Guyot, ODP Site 865): Greenhouse climate and superimposed hyperthermal events

We investigated the response of late Paleocene-middle Eocene (~60-37.5 Ma) benthic foraminiferal assemblages to long-term climate change and hyperthermal events including the Paleocene-Eocene Thermal Maximum (PETM) at Ocean Drilling Program (ODP) Site 865 on Allison Guyot, a seamount in the Mid-Pacific Mountains. Seamounts are isolated deep-sea environments where enhanced current systems interrupt bentho-pelagic coupling, and fossil assemblages from such settings have been little evaluated. Assemblages at Site 865 are diverse and dominated by cylindrical calcareous taxa with complex apertures, an extinct group which probably lived infaunally. Dominance of an infaunal morphogroup is unexpected in a highly oligotrophic setting, but these forms may have been shallow infaunal suspension feeders, which were ecologically successful on the current-swept seamount. The magnitude of the PETM extinction at Site 865 was similar to other sites globally, but lower diversity postextinction faunas at this location were affected by ocean acidification as well as changes in current regime, which might have led to increased nutrient supply through trophic focusing. A minor hyperthermal saw less severe effects of changes in current regime, with no evidence for carbonate dissolution. Although the relative abundance of infaunal benthic foraminifera has been used as a proxy for surface productivity through bentho-pelagic coupling, we argue that this proxy can be used only in the absence of changes in carbonate saturation and current-driven biophysical linking.
