And then there were none: decrease of origination and the decline of Conulariida
Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.Abstract Although the evolutionary history of conulariids has been widely studied, previous works have focused mostly on limited time intervals. In this paper, we examine the diversity dynamics of the group throughout its entire history, using various mathematical approaches.

Tectonics, Volume 45, Issue 3, March 2026.Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

The Depositional Record, Volume 12, Issue 1, February 2026.The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.
