We present the paleoenvironmental analysis based on sedimentary organic matter (SOM) of
alluvial-lacustrine-transitional deposits that crop out in the east portion of the Araripe Basin …

Abstract The early Albian Oceanic Anoxic Event (OAE), ie, OAE1b, is well documented in
western Tethys and in the primary North Atlantic Ocean, but has not yet been reported from …

Cretaceous climate records provide evidence that major volcanic pulses with duration of 10
3 to several 10 5 yr triggered changes in climate and oceanography. Black shales of …

Abstract The Cenomanian–Turonian boundary interval is generally considered a critical time
for planktonic foraminifera due to the environmental perturbations associated with Oceanic …

Abstract The Cretaceous Period (145-66 Ma) provides an opportunity to obtain insights into
the adaptation of the climate system to increased atmospheric greenhouse gas …

Marine mudstone sediments recovered from multiple boreholes drilled in southeast
Tanzania yield some of the best preserved Turonian microfossils in the world, and these …

Abstract The Barremian and Aptian were times of global plate reconfiguration and profound
changes in the ocean–climate system, culminating in the worldwide deposition of lower …

Abstract Fossils from the Araripe Basin (northeastern Brazil) are known for their remarkable
preservation of vertebrates and invertebrates, even including soft tissues. They occur in …

Hypotheses on the age and possible antiquity of the modern deep-sea fauna put forward to
date almost all agree on the assumption that the deep-sea fauna is largely the result of …

Carbon cycle perturbations dramatically affected the ocean-climate system during the Aptian–
Albian transition. However, the chronology of this interval is still intensively debated. Here …
