Burrowing K/T Survivors When it comes to the mass extinction that marked the Cretaceous/Tertiary (K/T) boundary 65 million years ago, what it all came down to, researchers say, is that only those who hid had a chance to survive. |

Meteor Crater's Slow Impact New findings suggest that rather than one large meteorite striking the ground at a high velocity, a lower velocity, pancake-shaped swarm of meteorite pieces -- formed from the explosion a larger meteorite -- likely carved out Meteor Crater. |

Sizing up a Crater New modeling of the impact of an Eocene extraterrestrial projectile in what is now the Chesapeake Bay shows that it was smaller than previously thought, and could help better predict the effects of future potential impacts. |

Dinosaur mass extinction may have been triggered by acid rain Most scientists accept the principal cause of the Cretaceous -- Tertiary mass extinction was a 10km asteroid hitting the Yucatan peninsula, but the precise mechanism by which this caused the extinction remains controversial. |
