An asteroid strike may not only account for the demise of ocean and land life 65 million years ago, but the fireball's path and the resulting dust, darkness and toxic metal contamination may explain the geographic unevenness of extinctions and recovery.
A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago.

With implications for present climate, new data links past spike in temperature with increased voraciousness of plant-eating insects
A new study of melted rock ejected far from the Yucatan's Chicxulub impact crater bolsters the idea that the famed impact was too early to have caused the mass extinction that killed the dinosaurs 65 million years ago.
