A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, Volume 309, Issue 11, Page 3091-3105, November 2026.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Structural interpretation of the Yunyakha area based on the sedimentation model of the Bolshaya nadota isolated carbonate platform [PDF]

Нефтегазовая геология: Теория и практика
The 1-Yunyakha borehole is located in the Polar Urals, where the Elets and Lemva structural zones are in contact. Sedimentological analysis can be performed on paragenetic associations by examining core samples from the Late Devonian - Early ...

The Magnetic Signature of Shear Zones in Marbles and Experimental Simulations

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
This dataset explores how strain, microstructure, texture and magnetic susceptibility interact in natural and experimental shear zones. It includes data from low‐ and high‐temperature marble shear zones and analogue experiments simulating different deformation regimes.

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 645-667, October/December 2026.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Multiple Subduction–Exhumation Cycles and Episodic Hydration–Metasomatism of an Oceanic Eclogite Block: Implications for Thermal Structure Evolution and Mass Transfer at the Subduction Interface

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The rarity of natural rocks that specifically record the physicochemical conditions of the subduction interface strongly hampers pertinent studies on metamorphic trajectories of high‐pressure (HP) rocks and related fluid–rock interactions. This study examines an oceanic eclogite block from the Huwan shear zone in the Hong'an orogen.

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

New Phytologist, Volume 252, Issue 1, Page 54-68, October 2026.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Early Devonian eurypterids with Bohemian affinities from Catalonia (NE Spain) [PDF]

, 1997
The sequence of early Lower Devonian (Lochkovian) strata with dominant anchimetamorphic shales of the Olorda Formation yielded numerous remains of eurypterids. These belong to the Family Pterygotidae and are represented by dominant species of Acutiramus (
