Plants Uptake Substantial Water From the Surface Organic Layer in Highly Permeable Karst Critical Zones

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Plants growing in highly permeable karst critical zones are exposed to shallow soils and rapid hydrological turnover. The surface organic layer is recognized as a key ecohydrological interface in these environments, yet its direct contribution to plant water uptake has rarely been quantified.

Tectono‐Stratigraphic Evolution of a Shared Foreland Basin: A 3D Geomodel and Detrital Flux Reconstruction for the Pliocene‐Pleistocene of the Po‐Plain Basin (Northern Italy)

open access: yesBasin Research, Volume 38, Issue 5, September‐October 2026.
The Plio‐Pleistocene succession of the Po Plain Basin was interpreted basin‐wide using seismic profiles and well data, identifying six major tectonic unconformities. Sediment volumes were calculated and decompacted to assess tectonic and climatic controls on basin infill, revealing a marked increase in detrital flux after 1.5 Ma, coincident with the ...

Provenance Constraints on Early India–Asia Collision: Evidence From the Late Cretaceous–Early Cenozoic Sulaiman–Katawaz Basin Fill

open access: yesBasin Research, Volume 38, Issue 5, September‐October 2026.
Integrated detrital zircon U–Pb, Nd–Sr isotopes and thermochronology record western Indian‐margin provenance reorganisation. Late Cretaceous–Palaeocene sediment supply was Indian‐affinity; Asian‐affinity input appeared across the Palaeocene–Eocene transition (~56.5–54.7 Ma), suggesting India–Asia collision was underway, while mixed provenance persisted

Fluid Pathways and Sources Driving Recurring Pockmark Formation on the Chatham Rise, New Zealand

open access: yesBasin Research, Volume 38, Issue 5, September‐October 2026.
Quasi‐3D seismic data interpretation and spatial pattern analysis indicate that pockmark formation on the SW Chatham Rise is likely driven by a combination of compaction‐related dewatering during polygonal faulting and silica diagenesis, coupled with deeply‐sourced, possibly CO2‐rich fluids from subducted limestones migrating along prominent basement ...

Dolomitic Microfossil Preservation in a Cryogenian Microbial Reef, Arkaroola (South Australia)

open access: yesGeobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Microbial dolostones that now form the Arkaroola reef, northern Adelaide Rift Complex, and were deposited during the Cryogenian interglacial period, display a wide range of meso‐scale stromatolite morphotypes in outcrop. Microcharacterisation involving optical microscopy, combined scanning electron microscopy and energy dispersive spectroscopy

Thallium Isotopes Across the Smithian‐Spathian Boundary: Evidence for Anoxia Throughout Most of the Early Triassic

open access: yesGeobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Following the largest known Phanerozoic extinction, the end‐Permian mass extinction, the Early Triassic is often considered an interval of slow biotic recovery. During this time, the minor Smithian‐Spathian extinction occurred, further delaying the biotic recovery of this epoch.

Nonavian Feathers in a Late Triassic Archosaur

Science, 2000
Longisquama insignis was an unusual archosaur from the Late Triassic of central Asia. Along its dorsal axis Longisquama bore a series of paired integumentary appendages that resembled avian feathers in many details, especially in the anatomy of the basal region.

Tooth Ultrastructure of Late Triassic Haramiyidae

Journal of Dental Research, 1984
Six molars of Haramiyidae from the French lower Rhaetic were examined by scanning and transmission electron microscopy, and by electron diffraction. Typical polished wear facets were located on the tops and on the occlusal bases of cuspids. Enamel was found to have had a structural pattern defined as "pre-prismatic", consisting of a repetitive pinnate ...

MOLAR OCCLUSION IN LATE TRIASSIC MAMMALS

Biological Reviews, 1968
Summary1. A new genus and species of late Triassic mammal, Megazostrodon rudnerae, from Lesotho in southern Africa is described. The molars are similar to those of the British Eozostrodon parvus except that they are slightly larger and the upper molars have a large external cingulum supporting well‐developed cusps.2. Molar occlusion is discussed in two
