Mixed Reception for Indian Meteor Theory

By October 20, 2009

Follow me on:

I recently reported about a stunning piece of research claiming that the extinction of the dinosaurs was caused by the impact of a huge meteor in western India, not the Yucatan Peninsula, as is the accepted wisdom. Well, according to this article on MSNBC, Texas Tech's Sankar Chatterjee just delivered his paper to a convention of the Geological Society of America, and not everyone was convinced.

The main objection to the Indian meteor theory boils down to this: what are the odds of two separate meteors striking the earth within a few (or ten thousand, or hundred thousand) years of each other, 65 million years ago, when such massive impacts are usually separated by vast aeons of time? It's conceivable, Chatterjee says, that both meteors split off in the earth's atmosphere from a larger object, but that doesn't answer the objections of other parties, who wonder if Chatterjee is misinterpreting the detritus from the Chicxulub crater (which reached all parts of the globe) as evidence for a new meteor impact.

Bob:
Just came across your stuff. Very nice. One minor correction: Bakker was not an advisor to Jurassic Park. Horner was the principal advisor and I was the second. Bakker talked to artists. But his self-promoting so annoyed Spielberg that he had Bakker killed (at least a look-alike) in Lost World.

Don are you serious about Spielberg being annoyed by Bakker?
