Microbial endolithic community at Meteor Crater

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 955-962, June 2026.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

Sedimentology, Volume 73, Issue 4, Page 1225-1243, June 2026.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Microbially induced sedimentary structures in fluvial settings: the gas domes from the Bolzano Megacaldera (Permian, Italy)

Sedimentology, Volume 73, Issue 4, Page 914-944, June 2026.
ABSTRACT Gas domes serve as some of the earliest and most persisting indicators of life on Earth, yet their documentation in continental environments remains sparse. This study aims to bridge this gap by examining gas domes within the Permian fluvial succession of Monte Luco, located in the caldera of the Bolzano Supervolcano. These structures occur as

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.
