Was Last Straw for DinosaursRead All About It!

The demise of the dinosaurs is the world's ultimate whodunit. Was it a comet or asteroid impact? Volcanic

eruptions? Climate change?In an attempt to resolve the issue,

scientists at the Berkeley Geochronology Center (BGC), the

University of California, Berkeley, and universities in the Netherlands and the United Kingdom have now determined

the most precise dates yet for the dinosaur extinction 66 million years

ago and for the well-known impact that occurred around the same time.

The dates are so close, the researchers say, that they now believe the comet or asteroid, if not wholly responsible for the global extinction, at least dealt the

dinosaurs their death blow.
