Anyone more than a few years old in May, 1980 probably recalls the eruption of Mt. ![]() Needless to say, be very happy that you weren't around when the meteor hit the Yucatan Peninsula. Scientists who've studied the resultant crater estimate that the meteor itself was about 6 to 9 miles in diameter. They've hypothesized that when it hit the Yucatan, it released energy equivalent to a billion times what was released in the Hiroshima and Nagasaki atomic bombs combined! It's what has been termed "the biotic revenge hypothesis". In recent years we've pretty much all concluded that the dinosaurs were killed off by a giant meteor that struck the Earth 66 million years ago. A recently published study by Michael Frederick of the University of Baltimore and Gordon Gallup of the State University of New York at Albany proposes that the dinosaurs began declining BEFORE the Chicxlub meteor impact. It isn't that the meteor was unimportant, just that it can't explain everything that happened. Let's take a look at the argument. ![]() ![]() No doubt about it, the dinosaurs that roamed the Earth millions of years ago were big, powerful, and likely very fierce.
