Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

open access: yesSedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...
