Biogeochemical Traits of a High Latitude South Pacific Ocean Calcareous Nannoplankton Community During the Oligocene. [PDF]
Paleoceanogr PaleoclimatolMarine phytoplankton community composition influences the production and export of biomass and inorganic minerals (such as calcite), contributing to core marine ecosystem processes that drive biogeochemical cycles and support marine life.

Scaled biotic disruption during early Eocene global warming events [PDF]
Biogeosciences, 2012 Late Paleocene and early Eocene hyperthermals are transient warming events associated with massive perturbations of the global carbon cycle, and are considered partial analogues for current anthropogenic climate change.

Paleogene calcareous nannoplankton evolution: the fertility link [PDF]
The Paleontological Society Special Publications, 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 extinctions, diversity increased progressively throughout the late Paleocene and early Eocene and reached a ...

Calcareous nannoplankton of the Red Sea
, 2008 The objective of this thesis is to understand the calcareous nannoplankton response to past environmental changes in the northern Red Sea over the last 60,000 years. Calcareous nannoplankton findings, supplemented by geochemical and sedimentological data, were compared with other marine and terrestrial proxy records and discussed with respect to the ...

Paleoenvironmental Stasis for the Bioturbating Community During the Paleocene-Eocene Thermal Maximum at the Southern Iberian Margin. [PDF]
GeobiologyABSTRACT During the Paleocene‐Eocene Thermal Maximum (PETM), there was an increase in global temperatures and emissions of isotopically depleted carbon, resulting in a negative carbon isotope excursion (CIE). This climatic event caused a widespread ocean deoxygenation, leading to substantial biotic turnover.

Biostratigraphy of Cretaceous calcareous nannoplankton
, 2007 The stratigraphical distribution of selected species of calcareous nannoplankton from sections of Cretaceous deposits in Tunisia, France, The Netherlands, West Germany, Great Britain, Denmark, Turkey, Oman and New Jersey was studied. A number of Late Cretaceous lineages was recognised, on which a proposal for a revised zonation is based.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
Geophysical Monograph Series, Page 83-102., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]
J AnatA fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Slimehead Size Through Time: Testing the Temperature-Size Relationship in Late Cretaceous Trachichthyidae. [PDF]
Ecol EvolIn this study, we use the extensive fossil record of the extinct Late Cretaceous Trachichthyid fish genus, Hoplopteryx, from the British Chalk Group to explore how this family responded to past climate change events. Our study is the first to demonstrate that seawater palaeotemperature, estimated from oxygen stable isotope values, is a significant ...

Late Neogene evolution of modern deep-dwelling plankton [PDF]
Biogeosciences, 2022 The fossil record of marine microplankton provides insights into the evolutionary drivers which led to the origin of modern deep-water plankton, one of the largest components of ocean biomass. We use global abundance and biogeographic data, combined with
