Were late Gomphotheres (Plio-Pleistocene) of the Siwaliks at more Stress as compared to early Gomphotheres (middle to late Miocene)?

open access: yesJournal of Bioresource Management, 2020
Gomphotheres existed in the Siwaliks from the middle Miocene (14.2Ma) to the middle Pleistocene (0.8Ma) and became extinct later on. In this paper, we tried to discuss the reasons of such extinction of gomphotheres in the lower Pleistocene time span by ...

Contribution of the coupled atmosphere–ocean–sea ice–vegetation model COSMOS to the PlioMIP2 [PDF]

open access: yesClimate of the Past, 2020
We present the Alfred Wegener Institute's contribution to the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2) wherein we employ the Community Earth System Models (COSMOS) that include a dynamic vegetation scheme.

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.

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 ...

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).
