Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

The caliph and the falcons: a ninth‐century history from Iceland to Iraq

open access: yesEarly Medieval Europe, Volume 34, Issue 2, Page 299-322, May 2026.
In the late ninth and early tenth centuries, an extraordinary number of falcons were given to the ʿAbbāsid caliphs in Baghdad, many of which were white. Gifts from competing dynasties in the northern provinces of the Caliphate, at least some of these birds were almost certainly gyrfalcons from near the Arctic Circle.

Towards red listing understudied tropical insects: A case study of the dung beetles of Sabah, Malaysian Borneo

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 511-529, May 2026.
We performed an IUCN Red List assessment for 159 dung beetle species from Sabah, Malaysian Borneo. Due to the lack of population demographic data, only Criterion B (i.e. geographic range) could be applied. Our findings show that the IUCN Red List Criteria can be applied to insect species based solely on occurrence data but highlight the importance of ...

Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 843-872, May 2026.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

Fascinating single‐cell red algae: models for evolution and adaptation

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1424-1437, May 2026.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

A >300 Myr Long‐Lived Topographic Highland Along the Northern North China Craton Margin Driven by Multistage Continental Convergence

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.
