It is well established that greenhouse conditions prevailed during the Cretaceous Period (~
145–66 Ma). Determining the exact nature of the greenhouse-gas forcing, climatic warming …

It is predicted that under a warming climate, wildfire frequency will likely increase. The
increase in fire activity is hypothesized as a likely consequence of increased atmospheric …

Archaeal membrane lipids are widely used for paleotemperature reconstructions, yet these
molecular fossils also bear rich information about ecology and evolution of marine ammonia …

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a∼ 9‰
increase during the Cenozoic interpreted as reflecting either a change in continental silicate …

Abstract Oceanic Anoxic Event 2 (Cenomanian–Turonian: ca 94 Ma) represents a major
palaeoceanographic phenomenon that took place during an interval of extreme global …

This study describes integrated, astronomically tuned age models for a relatively expanded
section of the Eagle Ford Group (Texas, USA) from the Shell Iona-1 research core, which …

Marine ammonia-oxidizing archaea (AOA) are among the most abundant of marine
microorganisms, spanning nearly the entire water column of diverse oceanic provinces …

Oceanic Anoxic Event 2 (OAE 2), occurring∼ 94 million years ago, was one of the most
extreme carbon cycle and climatic perturbations of the Phanerozoic Eon. It was typified by a …

Abstract Oceanic Anoxic Event 2 (OAE 2), during the Cenomanian‐Turonian transition (∼
94 Ma), was the largest perturbation of the global carbon cycle in the mid‐Cretaceous and …

Abstract The Cenomanian to Turonian boundary transition (ca. 95–93 Ma) represents one of
the most profound global perturbations in the carbon cycle of the past 140 my This interval is …
