The Paleocene-Eocene Thermal Maximum (PETM; ca. 55.8 Ma) is thought to coincide with a
profound but entirely transient change among nannoplankton communities throughout the …

We combine stable isotope, calcareous nannoplankton, and benthic foraminiferal records for
Ocean Drilling Program Sites 1262 (paleodepth~ 3,500 m) and 1263 (paleodepth~ 1,500 m) …

Oceanic carbonate chemistry during the Cenozoic has affected the climatology, ecology,
and marine geology of our planet; yet, we have limited means to know the evolution of that …

Two hyperthermal events with different carbon cycle perturbations occurred across the
Cretaceous-Palaeogene boundary, ie, the late Maastrichtian Warming Event and the Early …

The rock record of organic carbon abundance and its isotopic composition is consistent with
the evolution of life more than 3800 million years ago (Ma). Despite this, there are very few …

Abstract The Paleocene‐Eocene Thermal Maximum (PETM),∼ 55.53 million years before
present, was an abrupt warming event that involved profound changes in the carbon cycle …

Understanding the role of deep-sea biota across global warming events in the past is key to
unravel climate system dynamics during periods of increased pCO 2 levels. Here we present …

Several prominent negative carbon isotope (δ 13 C) excursions are observed during the
Ediacaran-Cambrian (EC) transition, reflecting large perturbations of the carbon cycle in the …

The origination of six nannoplankton species in the late Paleocene to middle Eocene
involves significant change in the entire nannofossil assemblage. The change began at the …

The Paleocene epoch was characterized by global climate fluctuations and major carbon-
cycle perturbations. During the greenhouse climate that characterized the early Cenozoic, a …
