Seismic stratigraphy of the Ontong Java Plateau [PDF]

, 1993
The Ontong Java Plateau, a large, deep-water carbonate plateau in the western equatorial Pacific, is an ideal location for studying responses of carbonate sedimentation to the effects of changing paleoceanographic conditions.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Seismic-based structural framework and sequence stratigraphy of the Bakr–Amer–Al Hamd fields, central Gulf of Suez, Egypt: implications for hydrocarbon exploration

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
The Miocene succession of the Bakr–Amer–Al Hamd fields, central Gulf of Suez, Egypt, is interpreted using seismic integration and well logs to delineate its structural and sequence stratigraphic framework.

Early to middle Miocene foraminifera from the deep-sea Congo Fan, offshore Angola [PDF]

, 2008
Analysis of a 630m section of an exploration well penetrating the distal part of the Congo Fan (~2000m water depth) yielded high abundance and diversity assemblages of agglutinated and calcareous benthic foraminifera.

Textural variations in Neogene pelagic carbonate ooze at DSDP Site 593, southern Tasman Sea, and their paleoceanographic implications [PDF]

, 2004
Changes in Neogene sediment texture in pelagic carbonate-rich oozes on the Challenger Plateau, southern Tasman Sea, are used to infer changes in depositional paleocurrent velocities.

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...

Understanding the Middle Miocene Climatic Optimum: Evaluation of Deuterium Values (δD) Related to Precipitation and Temperature [PDF]

, 2013
The Middle Miocene Climate Optimum was a unique warming period in the Earth’s geologic history, when a high global mean annual temperature was accompanied by a relatively low global CO2 concentration. Hydrogen isotopic signals (specifically molecular δD,

The Monterey event in the Mediterranean: A record from shelf sediments of Malta [PDF]

, 1996
Oligo-Miocene carbonate platform and shelf sediments outcropping on the Maltese Islands provide an excellent archive of the paleoceanography of the central Mediterranean.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.
