Organic petrology developed as coal petrology at the beginning of the 20th century
dedicated mainly to the study of coals because of their utilization in industry. Coal petrology …

An exhaustive biostratigraphic study based on the calcareous nannofossil content from
Lower and Middle Jurassic Lusitanian Basin sections in Portugal is here presented. Located …

Global perturbations to the Early Jurassic environment (∼ 201 to∼ 174 Ma), notably during
the Triassic–Jurassic transition and Toarcian Oceanic Anoxic Event, are well studied and …

For much of the Mesozoic record there has been an inconclusive debate on the possible
global significance of isotopic proxies for environmental change and of sequence …

Abstract The Early Jurassic was marked by multiple periods of major global climatic and
palaeoceanographic change, biotic turnover and perturbed global geochemical cycles …

Abstract During the Pliensbachian–Toarcian interval of the Early Jurassic, there is a well-
known second order marine extinction that is observable at the species and genus levels …

Palaeoenvironmental and palaeoclimatic changes during the Toarcian Oceanic Anoxic
Event (T-OAE) are reported from two successions deposited in the Andean Basin (Chile) …

One of the main controversial themes in palaeoclimatology involves elucidating whether
climate during the Jurassic was warmer than the present day and if it was the same over …

Major extinction events appear coincident with the emplacement of large igneous provinces
