The early Toarcian biotic crisis (∼ 183 Ma), characterized in marine environments by abrupt
temperature fluctuations, included a hyperthermal event (Jenkyns Event) with sea-level …

During the early Toarcian multiple environmental perturbations led to the genesis of the
Toarcian Oceanic Anoxic Event (T-OAE), expressed by the widespread occurrence of black …

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
upheavals is essential for predictions about the fate of the diversity of life and the future of …

Standard sequence stratigraphy interpretations are commonly built upon the premise of
fairly constant sediment supply, leaving vast uncertainties about sequence architecture and …

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 uppermost Pliensbachian-Lower Toarcian sediments recovered from Llanbedr
(Mochras Farm) Borehole (North Wales, UK) were deposited in the Cardigan Bay Basin and …

Environmental changes governed the diversity of marine ecosystems and the evolution of
marine reptiles during the Jurassic. Abrupt climatic changes, mainly cooling, produced …

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 …

Abstract The uppermost Pliensbachian (Margaritatus Zone)-upper Toarcian (Pseudoradiosa
Zone) sediments (silty and variably calcareous claystones, marlstones, silty sandstones, and …
