Sea‐level highstand recorded in the Last Interglacial shallow marine deposits from the Tangier region, Morocco

ABSTRACT The Moroccan coast provides valuable insight into how large‐scale climate and sea‐level variations have manifested themselves at the regional level. In this paper, we present new findings from shallow marine deposits in the Achakkar Basin near Tangier, Morocco. Data from...

Late Glacial temperature, anoxia, and primary production in Lago di Mezzano, Central Italy

In the North Atlantic domain, the Late Glacial period (19–11.8 cal ka BP) is characterized by rapid, high-amplitude climatic changes. The amplitude of temperature change in the Central Mediterranean region remains debated because reconstructions are limited and often contradictor...

Enceladus-like geochemistry fuels methanogenesis under extreme CO 2 limitation

Saturn’s icy moon Enceladus features chemical signatures consistent with an alkaline soda ocean with H 2 production via hydrothermal water-rock reactions. Chemolithoautotrophic methanogenesis is thermodynamically favorable under these conditions, but it is unknown whether CO 2 sc...

Dating low-temperature hydrothermal fluid activity with in situ Rb/Sr geochronology of partially chloritized biotite

Chloritization of biotite by fluids is common in low-temperature tectonic regimes. Using three metapelites from the Tatric Superunit in the Western Carpathians (northern Slovakia), we demonstrated that in situ Rb/Sr geochronology of partially chloritized biotite can be used to da...

Direct evidence for scavenging as a primary feeding strategy in Pliocrocuta, an extinct genus of bone-cracking hyaenas

Abstract The carnivoran family Hyaenidae exhibits a complex evolutionary history of diverse trophic adaptations, including the consumption of almost entire carcasses, either predated or scavenged. The associated durophagy peaked within the subfamily Hyaeninae in a clade of ‘fully...

Receiver function imaging reveals Pyrenean-style crustal wedging in the Western Carpathians

The Alpine−Tethys suture in the Western Carpathians records the collision between the northern European passive margin and the Adria-derived Alps−Carpathians−Pannonian (AlCaPa) tectonic unit. Previous tectonic models, largely based on indirect evidence, proposed complex configura...
