Paleogene calcareous nannoplankton evolution: the fertility link
, 1992 Calcareous nannoplankton diversity varied greatly during the Paleogene. From extremely reduced values (~10 species) in the early Paleocene (circa 66.4 to 66 Ma, age estimates from Berggren, Kent and Flynn, 1985) following the terminal Cretaceous ...

Calcareous nannoplankton from the Southwest Pacific Ocean
, 1986 The positions of all cores recovered during Leg 90 in the southwest Pacific are shown within the standard calcareous nannoplankton zonation. The stratigraphic and regional occurrences and preservation of Paleogene calcareous nannoplankton found at Sites ...

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...

, 2013 At present about one third of the carbon dioxide (CO2) released in the atmosphere from fossil fuel burning is absorbed by the oceans. The invasion of anthropogenic CO2 into the oceans increases seawater acidity and decreases carbonate ion concentration ...

Paleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.Abstract The early Eocene Climatic Optimum (EECO; ∼53–49 Ma) was the warmest sustained global warming episode of the Cenozoic, accompanied by major alterations in terrestrial and marine biota. Here we detail changes in low‐latitude calcareous nannofossil assemblages at two tropical sites in the equatorial Atlantic (ODP Site 1258) and Pacific (ODP Site ...

Paleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.Abstract The Miocene Epoch (23.03–5.33 Ma) is receiving increased attention because estimated pCO2 and its associated warmth is comparable to projections over the next century. Well‐constrained sea‐surface temperatures in the tropics and northern latitudes express amplified warming during the Miocene Climatic Optimum (MCO; 16.9–14.7 Ma), yet data from ...
