Commentary: Reframing Massive Carbon Input During the PETM and a Grand 66 Million Year Geoscience Puzzle

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Despite decades of research, hundreds of peer‐reviewed papers, and considerable relevance to Earth's future, the rapid global warming and tremendous CO2 input at the start of the Paleocene‐Eocene Thermal Maximum (PETM) remain highly debated.

Paleomagnetic Evidence of Internal Rotation in the Eastern Qiangtang and Its Relation to Distributed Strike‐Slip Faulting in the Southeastern Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The southeastern Tibetan Plateau has undergone complex deformation due to the India‐Eurasia collision. Although late‐stage internal rotations are documented in the Lanping‐Simao Terrane to the south, it remains unclear whether similar processes have affected the north.

Oligocene-Miocene strontium isotopes of ODP Hole 120-747A

, 1994
This study tests and improves on previously published early and middle Miocene 87Sr/86Sr marine correlations, presents Sr isotopic age correlations for this interval using the new timescale of Cande and Kent [1992 doi:10.1029/92JB01202], and evaluates Sr

Phylogeny of the Electric Rays of the Family Narcinidae (Gill, 1862): Systematic Review and Evidence of the Dispersal Routes to America

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.

Geochemistry of Eocene/Oligocene sediments of ODP Site 177-1090

, 2005
The Agulhas Ridge, off the tip of Africa between the Atlantic and Indian Oceans, is ideally located to capture the evolution of Paleogene-early Neogene circulation patterns associated with global cooling.

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

The Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

How Does the Phasianidae Maintain Its Diversity in Central China?

Ecology and Evolution, Volume 16, Issue 6, June 2026.
ABSTRACT The hypothesis of allopatric speciation suggests that spatial separation is the major driver to speciation. The ecological niche theory suggests that differentiations in niche dimensions allow more species to co‐exist in ecological communities.

The utility of deep-water agglutinated Foraminiferal acmes for correlating Eocene to Oligocene abyssal sediments in the North Atlantic and Western Tethys

, 2005
Quantitative analysis of Deep-water Agglutinated Foraminifera (DWAF) assemblages from key ODP sites in the North Atlantic reveal the presence of stratigraphically-significant abundance maxima, that may be useful for correlating sedimentary sequences ...
