New Study Confirms Massive Asteroid Wiped Out Dinosaurs

March 5, 2010

(ChattahBox)—In case you were losing sleep over this scientific mystery, a group of international scientists have concluded that a large asteroid or even a comet, was responsible for wiping out the dinosaurs from the face of the Earth about 65 million years ago. The group of 41 experts thoroughly reviewed all available research data on the plight of the dinosaurs and ruled out other theories, including super-sized volcano eruptions.

The panel of scientists published their findings in the journal Science and presented their findings at the Lunar and Planetary Science Conference in Houston. The Cretaceous-Tertiary (K-T) mass extinction exterminated more than half of all species on the planet at the time, paving the way for the rise of mammals.

According to an account of the findings by the BBC, the giant space object crashed near the Yucatan Peninsula:

“Their review of the evidence shows that the extinction was caused by a massive asteroid or comet smashing into Earth at Chicxulub on Mexico’s Yucatan Peninsula. When the 10km-15km space rock struck the Yucatan, the explosive energy released was equivalent to 100 trillion tonnes of TNT – over a billion times more explosive than the bombs dropped on Hiroshima and Nagasaki.The huge crater that remains from the event is some 180km in diameter and surrounded by a circular fault about 240km in diameter.”

Dr Gareth Collins, one of the co-authors of the study, said the asteroid hit Earth “20 times faster than a speeding bullet.”

Scientists believe that a catastrophic space impact occurs about once every 100 million years and so far, about five such events have occurred on Earth.

    The real scientists, the ones with skin in this game, (which would be chiefly the Society of Vertebrate Paleontology), long ago rejected the [meteor caused dinosaur extinction] Alvarez hypothesis by more than four-to-one.

    This so-called ‘official” pronouncement by non-experts from other fields, changes nothing, settles nothing and, far from being “official’, is just about entirely irrelevant.

    Did the sky-watchers explain how come the meteor didn’t kill off the frogs who should have been first to die out? How the meteor went about killing off every single dinosaur in every environment, from ocean to to mountaintop, swamp to upland forest to desert, with a *zero* survival rate? I didn’t think so. They should go back to their telescopes and leave this subject to those qualified to discuss it…
