Seems the grand theory that dinosaurs were wiped out by meteoric impact has run into trouble again. The Chicxulub impact is alleged by this new study to have been insufficient to cause enough damage to the climate to wipe out a tough genus that had ruled the Earth for hundreds of millions of years.
Instead, scientists are beginning to believe that they were wiped out by imaboringperson's and Tigger's favourite phenomenon, global warming (and global cooling) due to CO2. This time released not by man, but like the other three mass extinctions, by supervolcanos and continent-wide lava flows.
Probably this argument will never be conclusively solved. We should get a really powerful telescope, travel 85 million light years away, and have a look for ourselves. Now, if only that was scientifically possible... :inquisitive:
