Causes and Climatic Consequences of the Impact Winter at the Cretaceous‐Paleogene Boundary
Geophysical Research Letters, 2020Prolonged periods of low light and cold temperatures at Earth's surface are hypothesized effects of the end‐Cretaceous asteroid impact. However, debate remains about the causes and consequences of this “impact winter.” We perform simulations of the ...

Plate-tectonic processes have long been thought to be the major cause of the Cenozoic global carbon cycle, and global cooling by uplift of the Tibetan Plateau through enhancing silicate weathering and organic carbon burial and/or by weathering of ...

A parapithecid stem anthropoid of African origin in the Paleogene of South America
Science, 2020A South American anthropoid Although there are many primate lineages in the Old World, it is thought that the New World is home to just one group, the platyrrhine monkeys, which appear to have colonized the region during the Eocene.

Cretaceous–Paleogene boundary events
Palaeogeography, Palaeoclimatology, Palaeoecology, 2007The Cretaceous–Paleogene (K–Pg) boundary is recognized as one of the major catastrophic perturbations which affected the marine and terrestrial ecosystems and changed the earth's history and the path of evolution forever. Following this, the story of the K–Pg boundary has fascinated everyone interested in the history of life and death on our planet. In

Editorial: Advances in Paleogene research
Newsletters on Stratigraphy, 2017In the search for an improved understanding of Paleogene evolution a session was organised by the International Subcommission on Paleogene Stratigraphy (ISPS) during the 2nd International Congress on Stratigraphy held in Graz, Austria in July 2015, and the collection of papers presented in this volume is a result of this conference.

An Austral radiolarian biozonation for the Paleogene
, 2020: We have integrated southern mid- and high-latitude (Austral) radiolarian biozonations with the well-established low-latitude (Tropical) biozonation using new biostratigraphic and magnetostratigraphic constraints on radiolarian bioevents in the ...

The Paleogene chapter of Svalbard history is a quite distinct one. It begins with an unconformity, albeit a sub-parallel one representing a late Cretaceous hiatus. Resting on Albian and older strata, the Van Mijenfjorden Group of six formations totals a thickness of about 2500 m in the Central Basin of Spitsbergen.
