Sedimentary lithofacies, petrography and diagenesis of the Kapuni group in the Kapuni Field, Taranaki Basin, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science with Honours in Earth Science at Massey University, Palmerston North, New Zealand [PDF]

, 2004
The reservoir architecture and quality of the Kapuni Group sandstones in seven wells (Kapuni−1, −3, −8, −12, Deep−1, 14 and −15) in the Kapuni Field are characterised using available core and digital geophysical log data.

The Gashatan (late Paleocene) mammal fauna from Subeng, Inner Mongolia, China [PDF]

, 2008
The Paleocene–Eocene boundary is of particular importance for the evolution of mammals and the poorly known Asian mammal faunas from this period have received much attention.

Note “Paleocene” or “Palaeocene”

Bulletin of the Geological Society of Denmark, 1999
There seems to be some doubt as to which of the spellings “Paleocene” or “Palaeocene” should be used in manuscripts submitted for publication in Europe, while in North America the spelling “Paleocene” is standard. The latter is not surprising, as in North America the prefix paleo- is also used in terms such as Paleozoic, paleomagnetism, etc. In Europe,

"Hot and sticky" and "cold and damp" pyroclastic eruptions, and their relationship with topography: valley- and lake-filling ignimbrites, Ardnamurchan, NW Scotland

Volcanica
Pyroclastic density currents are complex mixtures of rock, ash and gas and represent significant hazards at many active volcanoes worldwide. Ignimbrites are the deposits of pyroclastic density currents and can be used to record the eruption dynamics and ...

Chronostratigraphic terminology at the Paleocene/Eocene boundary

, 2003
Integrated research over the past decade has led to the recognition of a short (150-200 k.y.) interval of Paleogene time within Chron C24r at ~55.5 Ma, formerly termed the late Paleocene Thermal Maximum (LPTM) but more recently the Paleocene-Eocene Thermal Maximum (PETM), that was crucial in the climatic, paleoceanographic, and biotic evolution of our ...

Temperature‐Driven Silicate Weathering Feedbacks Terminated the Middle Eocene Climatic Optimum

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Continental hydroclimate dynamics and its responses during the Middle Eocene Climatic Optimum (MECO, ∼40 Ma) remain largely unexplored. Here, we present high‐resolution multi‐proxy records from four East Asian lake basins that demonstrate precipitation, chemical weathering, and terrestrial input underwent multi‐phase changes during the MECO ...

Evolutionary Origin of Prolonged Delayed Fertilization in the Fagaceae

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Two‐year fruiting, in which fertilization and fruit maturation are delayed until the year after flowering, occurs in Fagaceae. Ancestral‐state reconstruction across a molecular phylogeny of 88 species representing all genera indicates a single origin of this strategy, followed by multiple reversions to 1‐year fruiting.

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

Biotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

TAXONOMY AND EVOLUTIONARY RELATIONSHIPS WITHIN THE CALCAREOUS NANNOFOSSIL GENUS ERICSONIA IN THE UPPER PALEOCENE

Rivista Italiana di Paleontologia e Stratigrafia, 2018
Detailed distribution ranges of the genus Ericsonia were obtained in the upper Paleocene interval from two deep-sea sections, ODP Site 1262 (South Eastern Atlantic Ocean) and Site 1215 (Eastern Equatorial Pacific Ocean), and were complemented with ...
