Relative Paleointensity Record of Integrated Ocean Drilling Program Site U1396 in the Caribbean Sea: Geomagnetic and Chronostratigraphic Observations in the Pliocene

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Continuous sedimentary records of paleomagnetic directional variability and relative paleointensity (RPI) provide valuable information on the evolution of the geodynamo while also facilitating stratigraphic correlation and age control.

Unraveling the mechanisms and implications of a stronger mid-Pliocene Atlantic Meridional Overturning Circulation (AMOC) in PlioMIP2 [PDF]

open access: yesClimate of the Past, 2023
The mid-Pliocene warm period (3.264–3.025 Ma) is the most recent geological period in which the atmospheric CO2 concentration was approximately equal to the concentration we measure today (ca. 400 ppm).

Young relicts and old relicts: a novel palaeoendemic vertebrate from the Australian Central Uplands [PDF]

open access: yesRoyal Society Open Science, 2016
Climatic change, and in particular aridification, has played a dominant role in shaping Southern Hemisphere biotas since the mid-Neogene. In Australia, ancient and geologically stable ranges within the vast arid zone have functioned as refugia for ...

The Invertebrate Life of New Zealand: A Phylogeographic Approach

open access: yesInsects, 2011
Phylogeography contributes to our knowledge of regional biotas by integrating spatial and genetic information. In New Zealand, comprising two main islands and hundreds of smaller ones, phylogeography has transformed the way we view our biology and ...

Oldest fossil remains of the enigmatic pig-footed bandicoot show rapid herbivorous evolution [PDF]

open access: yesRoyal Society Open Science, 2016
The pig-footed bandicoot, Chaeropus ecaudatus, is one of the most enigmatic Australian marsupials, which went extinct in the late 1950s probably as a result of European colonization.

Stratigraphy and development of the Late Miocene-Early Pleistocene Hawke’s Bay forearc basin [PDF]

open access: yes, 2004
A Late Miocene-Early Pleistocene mixed carbonate-siliciclastic sedimentary succession about 2 500 m thick in the Hawke’s Bay forearc basin is the focus of a basin analysis. The area under investigation covers 3 500 km2 of western and central Hawke’s Bay.

On the climatic influence of CO2 forcing in the Pliocene [PDF]

open access: yesClimate of the Past, 2023
Understanding the dominant climate forcings in the Pliocene is crucial to assessing the usefulness of the Pliocene as an analogue for our warmer future. Here, we implement a novel yet simple linear factorisation method to assess the relative influence of

Pliocene and Pleistocene chronostratigraphy and paleoenvironment of the Central Arctic Ocean, using deep water agglutinated foraminifera [PDF]

open access: yes, 1998
Deep-water agglutinated foraminifera (DWAF) were studied from Cores PS2177-5, PS2200-5, PS2212-3 and PS2185-6; from the R/V POLARSTERN ARK-VIII/3 Cruise in the central Arctic Ocean.
