Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.Abstract The Strathpeffer–Struie Lower Devonian LORS (Lower Old Red Sandstone) deposits of the Northern Highlands of Scotland contain the decidedly unusual ‘foetid beds’. These are interpreted as being deposited in a highly saline sulphate lake and associated playa mudflat, which developed in an intermontane basin in the Caledonian Mountains of ...

Increasing the Accuracy and Efficiency of Micromagnetic Tomography by Double Sided Scanning
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Paleomagnetic data are usually retrieved by subjecting bulk samples, for example lavas, to laboratory measurement protocols. In many instances, the data related to these protocols yield uninterpretable results caused by the presence of particles with adverse magnetic properties that blur the signal of the reliable magnetic particles.

Geomagnetic Variability in a Post‐Superchron Geodynamo: Insights From the Deccan Traps
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Studying long‐term geomagnetic field behavior is crucial for understanding Earth's evolution, as field variability reflects processes in the planet's deep interior. One key question concerns the relationship between field strength and polarity reversal frequency, particularly during the Cretaceous Normal Superchron (CNS), a prolonged interval ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.Abstract Eccentricity cycles in deep‐sea paleoclimate records suggest that astronomical forcing notably altered global temperatures and carbon cycle dynamics. Because changes in the distribution of insolation alone cannot explain the observed climate variability, climate‐carbon cycle feedbacks must have amplified the response.

Tectonics, Volume 45, Issue 1, January 2026.Abstract Recent observations and drilling campaigns have challenged the typical models for rifted margins by providing evidence for the existence of intermediate cases between the magmatic and amagmatic end‐members. In this contribution, we document the evolution of the Central Campos rifted margin, located in southeast Brazil, based on a combined ...

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.ABSTRACT Sequencing via target capture has been used to great effect in phylogenetic studies of organisms such as insects, arachnids and vertebrates. However, other taxa have received limited genomic attention despite their diversity and the intensity of research on such groups. Here, we describe generalised probe sets targeting ultraconserved elements

Basin Research, Volume 38, Issue 1, January–February 2026.An updated view of the southern part of the Cantabrian‐Pyrenean junction through a 3D geological model shows the first conclusive evidence for the ~65 km‐wide diffuse Pamplona transfer zone linking the Basque‐Cantabrian and Mauleon segments of the Pyrenean rift. This transfer zone also affected the style of deformation and configuration of the Pyrenean

New Phytologist, Volume 249, Issue 1, Page 448-459, January 2026.Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...
