Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.

Evaluation of existing knowledge of the tectonic history and lithospheric structure of South America [PDF]

While data is available on the lithospheric and crustal structure of the Andes region of South America, there is limited knowledge of these aspects of the eastern portion of the continent.

Radon‐222 as an Effective Tracer to Distinguish Groundwater Circulation Patterns in the Deep Fault‐Controlled Geothermal System

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Groundwater flow regulated by deep faults remains challenging to trace due to structural complexity. This study applies the noble gas tracer 222Rn combined with hydrochemistry and stable isotopes (δ2H, δ18O) to distinguish circulation patterns of geothermal springs along a major fault in the Tibetan Plateau.

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, Volume 61, Issue 5, Page 1291-1309, May 2026.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

When Snowpacks Shrink: Declining Weathering and Export Rates but Rising Stream Solute Concentrations in Warming Mountains

Hydrological Processes, Volume 40, Issue 5, May 2026.
In a snow‐dominated headwater catchment, snow‐dependent water storage controls silicate weathering and solute export. In the driest year with the least snow water equivalent (SWE), rates of silicate weathering and export rates of weathering products were about half and a third of those in the wettest year with the highest SWE.
