A simulation suggests that fine particles played a stronger role in cooling the planet and stalling photosynthesis after an asteroid impacted the Earth. By Miriam Fauzia On a spring day over 66 ...

We all know how the story goes: a large asteroid falls to Earth from space, slamming into the Yucatán Peninsula with 100 million megatons of force. The impact spawned tsunami waves best measured in ...

Dust from the Chicxulub impact may have plunged the planet into a cold, dark winter and halted photosynthesis. Mark Garlick / Science Photo Library Roughly 66 million years ago, a massive asteroid ...

A new study looking into what might have killed off dinosaurs determined that it is likely the ancient species were done in by a mighty cloud of dust. A massive plume of fine-grained dust may have ...

Oct. 30 (UPI) --A new study suggests that a prolonged dust cloud may have played a larger role than previously thought in the extinction of dinosaurs approximately 66 million years ago. A study ...

Scientists basically agree that an asteroid struck the Earth some 65 million years ago and its impact created the Chicxulub crater in Yucatan, Mexico. More controversial is the link between this ...

Human civilization and the rest of the modern world is built on a massive planet-sized dinosaur graveyard. John Hammond (Richard Attenborough) and his mad scientists at InGen did what they could to ...

A new study has finally revealed what caused dinosaurs to go extinct. While scientists long ago established that the species was eradicated some 66 million years ago by a city-sized asteroid, the ...

Red indicates regions where extinction falls off more rapidly at long wavelengths (the red end of the spectrum), while blue indicates that extinction is less dependent on wavelength. Regions with ...
