Asteroid that killed the dinosaurs had help from volcanoes, study says

LA Times  

Many scientists have long blamed a single culprit in the sudden and violent mass extinction that took out the dinosaurs: an asteroid that came screaming out of the skies some 66 million years ago. Researchers studying ancient lava flows in present-day India have also implicated the volcanic eruptions that they say turned massively deadly around the same time that the asteroid hit – eruptions that, together with the impact, would have filled the air and covered the earth with toxic fumes and dust, driving countless species to extinction. The amount of lava extruded “would correspond to something like half a million cubic kilometers,” said lead author Paul Renne, a geochronologist at the Berkeley Geochronology Center. It’s really big.” Some researchers have argued that it was this massive event that actually killed off the dinosaurs; others have said the volcanoes had little impact compared with the asteroid. And sure enough, after dating the rock samples, they were able to show that this change occurred within roughly 50,000 years of the asteroid’s arrival – which bolsters the case that the two were related.

The asteroid that killed the dinosaurs was NOT alone: Scientists discover evidence that a second devastating space rock smashed into Earth 66 million years ago

Daily Mail  

It's well known that the reign of the dinosaurs came to an end when a giant asteroid smashed into Earth 66 million years ago. Scientists from Heriot Watt University have discovered evidence that a second devastating space rock smashed into Earth in the same year. Now, the researchers have taken new high-resolution, 3D seismic images of the depression, which have …

CNN  

CNN — The age of the dinosaurs ended 66 million years ago with the ultimate bad day, not a prolonged period of climate change wrought by volcanic activity, according to new research. No, we show that Deccan Traps activity, if anything, might have buffered the ‘negative effects’ of the impact on climate, potentially boosting the recovery after the extinction event.” …

Meteorite impact, not India's Deccan Traps volcanoes, led to dino extinction: Study

India TV News  

Volcanic activity in India's Deccan Traps, previously thought to have contributed to the extinction of dinosaurs, did not play a role in their die-off, according to a study which suggests meteorite impact alone led to death of the ancient reptiles. While scientists had earlier focused on the role of volcanoes in causing the K-Pg mass extinction event which killed the …

Why did the dinosaurs go extinct? Debate rages on

CNN  

CNN — Ever since a huge crater was discovered off Mexico’s Yucatan Peninsula in the early 1990s, scientists have been confident that an asteroid slammed into Earth 66 million years ago and killed off the dinosaurs and most life on the planet. They say that any environmental impact from the eruptions and lava flows that occurred in the Deccan Traps …

The research sheds light on huge lava flows that have erupted periodically over Earth’s history. The asteroid impact that wiped off dinosaurs from the face of Earth 66 million years ago may have also reignited massive volcanic eruptions in India, half a world away from the impact site, a study has found.

The asteroid which killed the age of dinosaurs about 65 million years ago may have nearly punctured the Earth's crust, and temporarily caused the surface of the planet to behave like a slow-moving fluid, a new study has revealed. The crater resulted from the epic crash of an object about 10 kilometre wide, and the resulting impact is thought to …

Sixty-six million years ago, a 5-mile wide asteroid crashed into the Earth at 70,000 miles per hour, vapourising upon impact. But now researchers in the US have found more evidence for the theory that major volcanic eruption began just before the impact, possibly also playing a role in the extinction.
