Large igneous province (LIP) volcanism has been proposed as a key trigger of several major climate and environmental perturbations during the Phanerozoic Aeon. Large-scale carbon emissions associated with one or both magmatic degassing from Greater Ontong-Java Plateau (G-OJP) intrusion organic-rich sediments by High Arctic LIP (HALIP) sills have widely suggested Early Aptian Oceanic Anoxic Even...

Snakes are a remarkably diverse and successful group today, but their evolutionary origins are obscure. The discovery of snakes with two legs has shed light on the transition from lizards to snakes, but no snake has been described with four limbs, and the ecology of early snakes is poorly known. We describe a four-limbed snake from the Early Cretaceous (Aptian) Crato Formation of Brazil. The sn...

The Cretaceous Period is considered the archetypical greenhouse interval, yet there mounting evidence for intermittent cooler climatic phases throughout this geologic span. Few continental climate histories exist south of paleoequator, and fewer still Africa during time. Galula Formation one few exposed fossiliferous sedimentary successions from what now subequatorial that also contains paleoso...

A tectonically-controlled forced regression occurred on the western margin of French subalpine basin around Aptian–Albian boundary. It nearly emptied part Vocontian Trough during early and middle Albian. compressional pulse associated with vertical movements along Cevennes fault row its satellites is inferred. This correlated an inverse transgressive trend, both in Paris Basin northern chains. ...

The Early Cretaceous was a time of dramatic change for sauropod dinosaurs in North America. Between the Late Jurassic-aged Morrison Formation and overlying Early Cretaceous strata, there was a dramatic decline in sauropod diversity. Here, we describe a new sauropod that adds to the diversity of the Early Cretaceous, from strata that can be no older than the early Aptian, (125 Ma) some 25 millio...
