Which came first: the impact or the eruptions? That question is at the heart of two new studies in the Feb. 22 Science seeking to answer one of the most hotly debated questions in Earth’s geologic ...

Artwork of a pair of tyrannosaur dinosaurs surveying a volcanic landscape. This depicts a scene at the end of the Cretaceous period in Earths history. A massive meteorite has impacted the Earth, ...

There’s a solid consensus among scientists about what happened to the dinosaurs 66 million years ago: A mountain-sized meteorite crashed into the planet and triggered a mass extinction. The debris ...

Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final ...

A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and ...

An incredible outpouring of lava 66 million years ago could have set off environmental changes that killed off the dinosaurs, a new study finds. The research reports precise dates for India's Deccan ...

Sixty-six million years ago all the non-avian dinosaurs went extinct. We know this because of the abrupt end to the fossil record for these creatures—one geological moment they were there, the next ...

For decades, scientists have gone back and forth about whether massive volcanic eruptions or an asteroid impact — or maybe both — caused a mass extinction that saw the demise of all nonbird dinosaurs ...

Satellite image of the Deccan Traps, a large igneous province in India, which erupted around 66 million years ago in the southern hemisphere. The subsequent fast northward motion India moved the ...

Volcanic activity in modern-day India, not an asteroid, may have killed the dinosaurs, according to a new study. Tens of thousands of years of lava flow from the Deccan Traps, a volcanic region near ...

This is a preview. Log in through your library . Abstract Slot canyons, with extremely small width–depth ratios, are rare geomorphic features that develop under limited range of fluvial conditions. We ...

A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago played a role in the extinction event that claimed Earth's non-avian dinosaurs, and challenges ...
