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 …

A better understanding the functioning of Earth System in the context of past climatic

Abstract The end Pliensbachian–Toarcian is characterized by several carbon-cycle
perturbations and faunal turnovers (eg, ammonites and foraminifera), which are most likely …

The study of past climate changes is pivotal for understanding the complex biogeochemical
interactions through time between the geosphere, atmosphere, hydrosphere and biosphere …

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 …
