Paleomagnetic Constraints on the Separation of the Olongbuluke Block From the North China Block During the Late Cambrian–Middle Ordovician and Its Tectonic Significance

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian Block (a fragment of the South China Block) remains unclear.

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1713-1748, July 2026.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1702-1712, July 2026.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Abiotic Drivers of Groundwater Fauna Across Aquifer Types and Urban–Rural Gradients in the City of Halle (Saale), Germany

open access: yesEcohydrology, Volume 19, Issue 5, July/August 2026.
ABSTRACT Subterranean ecosystems in urban environments are exposed to multiple anthropogenic stressors that compromise groundwater quality and biodiversity. Rising groundwater temperatures, oxygen depletion, hydraulic disturbance and chemical contamination are among the main pressures.

Geophysical Investigation of Geothermal Potential in Southern Thailand: Insights From GGMplus Gravity

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Southern Thailand hosts numerous low‐ to medium‐enthalpy geothermal manifestations in a non‐volcanic setting. This study investigates the geothermal potential of the region through the integration of satellite‐derived gravity data and geological observations.
