The relevance of late MSA mandibles on the emergence of modern morphology in Northern Africa
North Africa is a key area for understanding hominin population movements and the expansion of our species. It is home to the earliest currently...

Taphonomic history and trophic interactions of an ammonoid fauna from the Upper Triassic Polzberg palaeobiota
The taphonomic mechanisms of a mono- to pauci-specific ammonoid fauna comprising 3565 specimens from the lower Carnian Polzberg Konservat-Lagerstätte ...

The Late Triassic Ischigualasto Formation at Cerro Las Lajas (La Rioja, Argentina): fossil tetrapods, high-resolution chronostratigraphy, and faunal correlations
Present knowledge of Late Triassic tetrapod evolution, including the rise of dinosaurs, relies heavily on the fossil-rich continental deposits of...

Paleoclimate-induced stress on polar forested ecosystems prior to the Permian–Triassic mass extinction
The end-Permian extinction (EPE) has been considered to be contemporaneous on land and in the oceans. However, re-examined floristic records and new...

Peak Cenozoic warmth enabled deep-sea sand deposition
The early Eocene (~ 56–48 million years ago) was marked by peak Cenozoic warmth and sea levels, high CO 2 , and largely ice-free conditions. This time...

Abrupt conclusion of the late Miocene-early Pliocene biogenic bloom at 4.6-4.4 Ma
The late Miocene-early Pliocene biogenic bloom was an extended time interval characterised by elevated ocean export productivity at numerous...

Indo-Pacific Walker circulation drove Pleistocene African aridification
Today, the eastern African hydroclimate is tightly linked to fluctuations in the zonal atmospheric Walker circulation
1 ,2 . A growing body of evidence...

Mercury spikes as evidence of extended arc-volcanism around the Devonian–Carboniferous boundary in the South Tian Shan (southern Uzbekistan)
Recently, the end-Devonian mass extinction (Hangenberg Crisis, 359 Ma) was identified as a first-order mass extinction, albeit not one of the “Big...

Impact of 10-Myr scale monsoon dynamics on Mesozoic climate and ecosystems
Earth’s orbital variations on timescales of 10 4 –10 5 years, known as Milankovitch cycles, have played a critical role in pacing climate change and...

Antiphased dust deposition and productivity in the Antarctic Zone over 1.5 million years
The Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages...

A well-oxygenated eastern tropical Pacific during the warm Miocene
The oxygen content of the oceans is susceptible to climate change and has declined in recent decades
1 , with the largest effect in oxygen-deficient...

VOLCORE, a global database of visible tephra layers sampled by ocean drilling
The VOLCORE (Volcanic Core Records) database is a collection of 34,696 visible tephra (volcanic ash and lithological or grain size variations)...

Weakening of the South Asian summer monsoon linked to interhemispheric ice-sheet growth since 12 Ma
The evolution and driving mechanism of the South Asian summer monsoon (SASM) are still poorly understood. We here present a 12-Myr long SASM record...

Anatomy of an extinction revealed by molecular fossils spanning OAE2
The Cenomanian–Turonian mass extinction (Oceanic Anoxic Event 2-OAE2) was a period of profound ecological change that is recorded in the sedimentary...

Calibrating the zenith of dinosaur diversity in the Campanian of the Western Interior Basin by CA-ID-TIMS U–Pb geochronology
The spectacular fossil fauna and flora preserved in the Upper Cretaceous terrestrial strata of North America’s Western Interior Basin record an...

Astronomical tuning of the Aptian stage and its implications for age recalibrations and paleoclimatic events
The Aptian was characterized by dramatic tectonic, oceanographic, climatic and biotic changes and its record is punctuated by Oceanic Anoxic Events...

Million-year-old DNA sheds light on the genomic history of mammoths
Temporal genomic data hold great potential for studying evolutionary processes such as speciation. However, sampling across speciation events would,...

Different triggers for the two pulses of mass extinction across the Permian and Triassic boundary
Widespread ocean anoxia has been proposed to cause biotic mass extinction across the Permian–Triassic (P–Tr) boundary. However, its temporal dynamics...

Cyclic evolution of phytoplankton forced by changes in tropical seasonality
Although the role of Earth’s orbital variations in driving global climate cycles has long been recognized, their effect on evolution is hitherto...

A continuous fish fossil record reveals key insights into adaptive radiation
Adaptive radiations have been instrumental in generating a considerable amount of life’s diversity. Ecological opportunity is thought to be a...
