Early evolutionary history of the seed
Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

AGU Advances, Volume 7, Issue 3, June 2026.Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

Fusulinids from the Upper Permian Kuma Formation, Southern Kyushu, Japan : With Special Reference to the Fusulinid Zone in the Upper Permian of Japan, 1953 The Kuma formation in the Kuma massif of southern Kyushu, about 900m. thick, consists of remarkable conglomerates, sandstones, shales and subordinately intercalated limestone lenses at four horizonz. Fusulinids herein described and illustrated are one new species of Codonofusiella, each one species of Rauserella and Dunbarula?, one new and one ...

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.

The Origin and Early Radiation of Archosauriforms: Integrating the Skeletal and Footprint Record.
PLoS ONE, 2015 We present a holistic approach to the study of early archosauriform evolution by integrating body and track records. The ichnological record supports a Late Permian-Early Triassic radiation of archosauriforms not well documented by skeletal material, and

Chronological link between deep-seated processes in magma chambers and eruptions: Pemo-Carboniferous magmatism in the core of Pangaea (southern Pyrenees) [PDF]
, 2014 In the Southern Pyrenees there are Upper Carboniferous–Lower Permian sedimentary basins with a significant volume of volcanic material derived from explosive eruptions (rhyolitic ignimbrites and andesitic flows).

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.
