Abstract The Early Jurassic Jenkyns Event (∼ 183 Ma) was characterized in terrestrial
environments by global warming, perturbation of the carbon cycle, enhanced weathering …

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 …

The application of carbonate clumped isotope (Δ 47) thermometry in deep-time is often
limited by modification of the original temperature signal by thermal resetting. New modeling …

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

Pliensbachian-Toarcian lacustrine shales in the Sichuan basin is characterized by two
organic matter-rich layers (Dongyuemiao and Da′ anzhai members) interlayered with an …

Seasonal variability in sea surface temperatures plays a fundamental role in climate
dynamics and species distribution. Seasonal bias can also severely compromise the …

Abstract The Toarcian Oceanic Anoxic Event (T-OAE; Early Jurassic, ca. 183 Ma) represents
an intense Mesozoic organic carbon burial event that was associated with the formation of …

The flooding of the Pliensbachian shelf of the North-South Axis of Central Tunisia during the
early Toarcian favoured the development of organic-rich facies in the most subsiding areas …

Study of the accretionary biomineralised hardparts of organisms (sclerochronology) can
make a useful contribution to palaeoclimatology. Ontogenetic sequences of isotopic data (δ …

The carbonate clumped isotope (∆ 47) thermometer is a powerful tool for temperature
reconstruction based on the thermodynamical 13 C—18 O bonding preference. Accurate …
