The Aalenian was a time marked by profound environmental and carbon cycle changes.
Still, the scarcity of detailed studies hinders a better understanding of the triggering …

Abstract The Triassic–Jurassic transition, which is here broadly defined as extending from
the Late Triassic through the Early Jurassic (~ 237 Ma to 174 Ma), was an important interval …

Coleoid cephalopod molluscs comprise squid, cuttlefish and octopuses, and represent
nearly the entire diversity of modern cephalopods. Sophisticated adaptations such as the …

Reconstructing temperatures of ancient oceans is important for understanding Earth's
climate in deep time. Belemnites have been used widely to estimate Mesozoic seawater …

Major carbon cycle disturbances reflected by carbon isotope excursions (CIE) have been
reported in the Jurassic successions of Euro-Boreal and Mediterranean basins. However …

Body-size reduction is considered an important response to current climate warming and
has been observed during past biotic crises, including the Pliensbachian–Toarcian crisis, a …

Abstract The Early Toarcian (Early Jurassic) global marine mass extinction is associated
